We love to see Sudbury smile.

Diligent brushing and flossing are crucial for maintaining a healthy, happy smile – but they’re not all you need. After all, tricky problems can develop that are difficult for an untrained eye to notice, leading to damage and decay.

That’s why Keenan Dental strongly recommends that patients of all ages attend an in-depth check-up and cleaning at least once every six months. This allows Dr. Scott Keenan and the rest of our team to learn everything we need to know about your unique smile, recommend treatment options if necessary, and give it a nice, fresh shine.

Your family life is busy, and we want to minimize the stress of making appointments for your family so they can get all the care they need.  We offer a wide array of general, cosmetic, and restorative services.  You’ll find everything you need right here in one convenient location.

Our wide variety of family dental care includes, but isn’t limited to, the following services:

  • Dental cleanings and exams
  • Digital x-rays
  • Tooth-coloured fillings
  • Root canals
  • Extractions
  • Crowns and bridges

Making sure your family stays current with professional dental cleanings and exams is the best way to protect their oral health. You have probably heard people say, “An ounce of prevention is worth a pound of cure”.  This is especially true when it comes to managing your oral health.

Regardless of the procedure we perform, you can be confident that our team will do whatever it takes to ensure that your time with us is as stress-free and comfortable as possible.

We Love Treating Children!

Our goal is to introduce children to dentistry at their own pace and to eliminate any negative feelings they might have. We see children starting at the age of three when they have most of their baby teeth. At this point in their young lives, we have the opportunity to help them develop positive feelings about dental care and motivate them to take care of their oral health as they grow.

For many people, losing a tooth can be devastating. In addition to affecting the sound of your speech and your ability to chew healthy foods, tooth loss also damages your oral health and your self-confidence.

While traditional reconstructive solutions like dentures and bridges have been around for many years, patients often find themselves dissatisfied with their look and feel, wishing more than anything that they could just have their original tooth back.

While our team at Keenan Dental can’t turn back the clock, we can offer you the next best option available via dental implants. Dental implants provide patients with a long-lasting, permanent, and beautifully seamless replacement that’s sure to give them something to smile about.

When choosing dental implants, our team will first need to perform a thorough evaluation of your jawbone and overall oral health so that we can determine whether you’re a viable candidate. If our findings are positive, we can help you take the next step towards the surgical placement of your new implant.

The secret behind the success of dental implants is that they replicate the root of your tooth, stimulating the jawbone and even rejuvenating the tissue in some cases. Dr. Keenan will be happy to recommend you to a trusted oral surgeon who can handle this portion of your treatment skillfully and comfortably.

Once your implants have been placed, you’ll need to undergo a period of healing. During this time, your new implant and your jawbone will form a strong, natural bond. Then, you’ll return to Keenan Dental so that we can design and place brand-new, quality restorations, completing your new and improved look.

For single implants, an all-ceramic crown is the ideal solution. We can also offer implant-retained prosthetics for patients who would like a more convenient and affordable option for replacing several teeth at once.

Once completed, dental implants provide exceptional strength and beauty to patients. They can be treated just like natural teeth, which means that no changes to your diet or oral hygiene routine are necessary. Better yet, with appropriate care and regular check-ups at Keenan Dental, dental implants can last a lifetime!

Contact our dental office today if you have any questions or if you’re ready to schedule an appointment. We accept new patients.

If you are missing several teeth or you are facing the loss of all your teeth, you probably have mixed feelings about the situation. At Keenan Dental we understand. Tooth loss is deeply personal, and it affects your health and your emotional well being in countless ways.

We want you to know that we are on your side, and we have helped many people in your situation. We also want you to know that tooth loss doesn’t mean that you are doomed to a fake-looking, uncomfortable smile with false teeth that slip, slide, and constantly embarrass you.

At Keenan Dental we’ll introduce you to modern dentures.

Many of our patients come to us worried that they are going to wind up with dentures like the ones they remember that their parents or grandparents wore.

The reality however, is far different!

Modern dentures are carefully customized to fit well and look natural. We take impressions and photographs and provide these to the lab, along with careful instructions, so that you get a one-of-a-kind fit and new teeth that complement your bone structure and natural skin tone.

The teeth in dentures from Keenan Dental are crafted to have the subtle variation that occurs in natural teeth. This helps prevent the artificial appearance that plagued denture wearers of the past.

If you are missing multiple teeth, we may discuss partial dentures. This is an affordable way to complete your smile and your chewing surface. Unlike complete dentures, which rely primarily on suction to stay in place, partial dentures are held in place with clasps that fit around your remaining healthy teeth.

Both types of dentures require regular care and maintenance to stay in good shape. We’ll provide you with the information you need to clean your dentures and recommendations for appropriate products. In general, plan to clean your dentures at least once a day to keep them fresh and free from bacteria. You should also return to our office regularly so we can check the fit of your dentures since your bone structure and gum tissue will change over time.

While the fit of modern dentures is considerably better than dentures of the past, particularly when it comes to upper dentures, there is still some risk of slipping. But we have a solution for that.

Strategically placed dental implants can be used to secure a denture in place. Once the denture is snapped over the implants, it won’t budge until you are ready to remove it!

We’d be happy to talk with you about your options and see if you are a good candidate for implant-supported dentures – a great way to combine the affordability of dentures with the stability and convenience of implants!

Is it time to talk about dentures? We’re here to help. Contact our dental office today if you have any questions or if you’re ready to schedule an appointment. We accept new patients.

Dental emergencies can happen anywhere, and often at the most inconvenient of times.

If you or a loved one is currently experiencing a severe injury or pain, please don’t hesitate to reach out to our team at Keenan Dental.

We do our best to see emergency cases the very same day as your initial call, and our wide variety of available services can treat several issues, including broken teeth, toothaches, and even missing teeth. In the meantime, Dr. Keenan can provide valuable guidance on how to handle your situation until you’re able to reach us.

Here are some helpful tips for the most common dental emergencies we see…

Rinse the affected tooth immediately with warm water. A cold compress should help alleviate any swelling as you travel to our office. Bring any pieces of the tooth (that you can find) with you to your appointment.

Try to find the tooth. If you can, rinse it carefully. You want to remove any debris from the tooth while keeping any bits of tissue attached.

Try to place the tooth in its socket and hold in place with very gentle pressure. You may wish to place a piece of gauze over the tooth to make it more comfortable.

If you can’t do this, place the tooth in a cup or plastic bag of milk and bring it with you to our office. Once you arrive, Dr. Keenan can examine you and the tooth to see if replacement is possible. The faster we can see you, the better chance we have of saving your tooth.

If you still have the crown, apply a small amount of toothpaste or dental wax to it and carefully reattach it to the appropriate tooth. This should work as a temporary fix until you’re able to reach our office.

First, rinse and floss around the tooth so that you can be sure there’s no debris that’s causing the pain. If pain persists, please contact us. Also, we strongly recommend that you don’t place an aspirin on the tooth as this might damage your gum tissue. Tooth pain is often the sign of an infection, which can be a serious problem if it is allowed to spread. Please don’t take a “wait and see” approach to tooth pain.

Apply a cold compress and go immediately to the nearest emergency room for treatment. If you’ve suffered a lost or broken tooth due to your injury, contact us so that we can arrange for treatment as soon as possible.

Time is of the essence in many dental emergencies, which is why you should contact Keenan Dental as soon as possible to schedule an appointment. Our skilled team will be sure to treat you with kindness, comfort, and personalized care while we work to give you back the whole, healthy smile you deserve.

With excellent preventive care, we can keep most dental problems to a minimum. But the fact is that even the very best care can’t prevent every single problem out there. Your teeth could still encounter cracks, deep cavities, and infections. If this happens, you want to know that they will be taken care of. Dr. Keenan and the dedicated team at Keenan Dental will provide you with the empathy and support you need during this difficult time.

Occasionally, there are reasons why a tooth needs to be extracted. These reasons might include severe decay or other structural damage, overcrowding, or a threat to the well-being of your other teeth. At Keenan Dental we know that this procedure isn’t exactly fun, which is why we always offer kindness, compassion, and several patient comfort measures that can help you relax.

Once we’ve removed the tooth, we’ll be happy to discuss replacement options as soon as possible so you can get back to enjoying the full, beautiful smile you deserve.

We can perform most extractions right here in our office. If you have a complex or surgical extraction, however, we may refer you to an oral surgeon as your comfort and safety are always our top priority.  We’re here to help. Contact our dental office today if you have any questions or if you’re ready to schedule an appointment.

Get the smile you want, minus the interruptions.

Invisalign are clear, transparent dental aligners and are an incredible advance in orthodontic technology. They are the ideal solution for correcting moderate crowding or spacing (1-6mm) of your front teeth, as well as for patients who are experiencing relapse from previous treatments.

The aligners are worn for 20 hours a day for two weeks, slowly moving your teeth into their intended position. Multiple aligners are used over time to complete the treatment, with the average treatment time being 14 months.

Is Invisalign right for you? Book an appointment today to explore your many options on your journey to a perfect smile.

When you think of mouth guards, you may picture generic plastic trays that protect your teeth during sports. At Keenan Dental, we do offer customized sports guards, but we can also use other special types of mouth guards to control teeth grinding, a condition also referred to as bruxism or bruxing.

Symptoms of Teeth Grinding
It’s normal to grind your teeth occasionally, especially in stressful situations. However, some people experience chronic teeth grinding (bruxism) that leads to painful symptoms like head and neck pain, the abnormal wearing of teeth, and temporomandibular joint dysfunction (usually abbreviated to either TMJ or TMD).

Are the uncomfortable symptoms of teeth grinding disrupting your life? If so, we encourage you to contact our dental office. In many cases, people grind their teeth during sleep without realizing it.

Using impressions of your teeth, we will create a customized night guard that is highly effective for reducing chronic teeth grinding and its symptoms. Depending on the severity of your grinding, we also have the option of using a device called an occlusal splint. This prevents your teeth from coming into contact with each other while you sleep.

Reasons for Teeth Grinding
After a thorough examination, we can determine the probable cause of your teeth grinding.

In general, chronic teeth grinding is often the result of:

  • Injury or trauma to the temporomandibular joint
  • Misaligned dental bite
  • Muscle tension

A misaligned dental bite can result in too much force placed on one side of your mouth. In this case, you can’t bite down evenly on all teeth. This causes your jaw to shift out of its normal position to bring the rest of your teeth together. All this constant, excessive force on your teeth, jaw joint, and surrounding muscles ultimately leads to painful symptoms in your head and neck.

Protect Your Oral Health with Athletic Mouth Guards
Frequently, dental injuries are a consequence of playing sports. Estimates indicate that nearly 40% of dental trauma occurs during sports, and 80% of these injuries affect at least one of the front teeth. Knowing these statistics makes it easy to see how important it is to protect your family’s teeth with a mouth guard during athletic activities.

Since we use impressions of your teeth, our athletic mouth guards are much more effective than generic guards purchased over the counter. They’re also made of a much more rigid material, and the result is superior protection for you and your children.

We’re here to help. Contact our dental office today if you’re bothered by teeth grinding or if you need a high-quality sports guard to keep your family’s teeth safe and healthy. We accept new patients.

Oral cancer isn’t a topic that’s discussed as much as periodontal disease and cavities in the dental office – but that doesn’t make it any less dangerous. Studies show that on average, one North American adult dies every hour from this disease, and half of people diagnosed won’t go on to live more than five years past that point.

Thankfully, there’s also a bright side – there is a high rate of successful treatment as long as oral cancer is caught early enough. That’s why Dr. Keenan and the rest of the Keenan Dental team make detecting and identifying signs of oral cancer one of our top priorities during check-ups.

With the help of an oral cancer screening, we can keep patients safe and confident in the state of their smile.


  • Consistently bleeding sores
  • A sore that heals slowly or not at all
  • Pain or numbness located in the mouth or lips
  • Lumps, thickened skin, or crusts within the mouth
  • Red or white spots or sores in the mouth
  • An unexpected colour change of the oral tissues

Our team wants to be your main line of defense against this destructive condition. During your regular check-ups, we’ll conduct an oral screening, carefully inspecting your soft tissue to determine if there are any cancerous cells or abnormal areas present.

If we do discover something suspicious, we can help you take the next steps toward a concrete diagnosis and further treatment, if necessary.

Contact Keenan Dental if you have any questions about our available services or you’d like to schedule an appointment for you or a loved one. We hope to provide you with kind, personalized care that leaves you with the excellent oral health and beauty you deserve.

We’re here to help. Contact our dental office today if you have any questions or if you’re ready to schedule an appointment. We accept new patients.

Today, nearly three out of four North Americans suffer from some form of periodontal disease (also known as gum disease). Unfortunately, many of those people don’t even know that they have it.

While this common condition may not even cause symptoms at first, it can quickly become dangerous if left untreated for too long, leading to inflammation, jawbone deterioration, and even tooth loss. Studies have even shown that it may be connected to serious health problems like heart disease, strokes, diabetes, and Alzheimer’s disease.

Here at Keenan Dental, we’re dedicated to keeping our patients safe and healthy, which is why we make effectively treating periodontal disease at the earliest possible stages a priority.

With the help of regular check-ups and available therapy options, Dr. Keenan can ensure that you and your loved ones enjoy happy, healthy smiles for years to come.

Quite simply, in the early or moderate stages of periodontal disease, most patients don’t have any symptoms they take notice of.

In a more severe stage of the disease, common symptoms include:

  • Red or tender gums
  • Bleeding during brushing and flossing
  • Loose (or mobile) teeth
  • Changes in the way your teeth come together
  • Bad breath that doesn’t resolve with improved oral hygiene or the addition of mouthwash
  • Teeth that appear longer than they used to (a sign of receding gums)

However, it’s important to remember that in many cases, easily noticeable symptoms may not show up until the disease has progressed. That’s why attending regular check-ups at Keenan Dental is so important.

We’re here to help. Contact our dental office today if you have any questions or if you’re ready to schedule an appointment.

At Keenan Dental we’re not just focused on effectively treating your oral health problems – we also want to keep them from happening in the first place! That’s why Dr. Keenan is happy to offer a preventive dentistry program that helps patients ages three and up by addressing specific needs at any given time.

Regular check-ups allow us to identify potential problems as early as possible, and our swift, effective treatment will be sure to keep your smile shining bright. We look forward to welcoming you and all your loved ones to our new southend facilities.

Hands down, the best way to keep your smile healthy is to visit our office every six months for professional cleanings and comprehensive examinations.

No matter how dedicated you are to brushing and flossing at home, office visits are necessary to remove the traces of plaque you simply can’t reach with a toothbrush or dental floss. Plus, our thorough examinations will help us identify any developing problems as early as possible so they can be treated with simple, conservative, less invasive treatments.

Regular x-rays are a key factor in timely diagnosis. At Keenan Dental, we use digital x-rays, which decrease radiation exposure by as much as 80%. They are instantly available for viewing and much better for the environment since they are stored electronically in your file and don’t require chemicals for developing.

Every examination includes a screening for oral cancer. While certain factors can increase your risk for developing cancer, including the combination of drinking alcohol and using tobacco, oral cancer can hit at any age. Early detection significantly improves your chances of successful treatment.

Healthy teeth begin early, and interventions like fluoride and sealants have been shown to greatly reduce the risk of cavities, or dental caries. Dental cavities are considered to be the most common childhood illness in North American children. Also that a whopping 84% of cavities suffered by children occur in the grooves of their teeth. This is understandable – after all, these grooves are often so narrow that a toothbrush can’t even fit into the spaces and remove plaque. Thankfully, a well-placed dental sealant from Keenan Dental can provide a valuable extra layer of protection for young and old smiles alike, and their placement is simple and painless.

Fluoride is a naturally occurring mineral that we paint on teeth after a cleaning to strengthen enamel. Sealants are a resin coating that we apply to the back molars to seal off and protect the deep grooves that can occur in these teeth from decay-causing bacteria.

The Sealant Placement Process
While children who’ve just had their permanent molars erupt are the most common recipients of dental sealants, adults with unusually deep grooves in the back teeth or a higher risk factor for decay may be prime candidates as well.

First, we’ll mildly etch your tooth to create a microscopically rough surface for sealant to stick to. Then, we’ll paint the tough, resin material over the grooves and use a high intensity light to quickly harden it in place.

The finished product will be virtually invisible, allowing you to enjoy an increased level of protection without worrying about your look. Dental sealants typically last from two to four years, with some staying in place for as many as ten years. Regular check-ups will allow Dr. Keenan to monitor their effectiveness and reapply when necessary.

Your temporomandibular joints (TMJs) may be small, but they serve a crucial purpose by attaching your lower jaw to your skull. This means that when they’re even slightly misaligned, it can cause a whole host of potentially debilitating symptoms, including serious migraines; face, neck, and shoulder pain; and even locking in one position.

With the help of occlusal adjustments and stabilizing splints, our team at Keenan Dental can alleviate discomfort and provide you with the relief you need.


Investing in a preventive plan is a great way to preserve your oral health, your smile’s beauty, and your overall quality of life. We’re here to help. Contact our dental office today if you have any questions or if you’re ready to schedule an appointment. We accept new patients.

Many patients fear the root canal procedure more than any other dental treatment.

The truth is, you don’t need to worry! The pain associated with a root canal usually comes from the symptoms of the infection, not the procedure itself. We provide painless root canal procedures that restore your health and comfort and allow you to keep your natural tooth. Our goal is to save your tooth because it is the best way to protect your oral health and the integrity of your smile.

You do not need to feel nervous about your root canal at Keenan Dentistry. Dr. Keenan is highly skilled at providing our patients with exceptional endodontic care.

When Is a Root Canal Necessary?
Root canal therapy is necessary to address an infection inside your tooth. Often, the first symptoms include pain, inflammation, and sensitivity. Other symptoms include discoloration of the tooth, facial swelling, and a small lesion on the gums.

Many infections will not go away on their own. We need to gain access to the infection and clean out the canal in order to assist with healing.

Root Canal Therapy Procedures
We use the most advanced rotary instrument technology to make this procedure as quick and painless as possible. We can handle most cases in-house, which means fewer offices to visit and less waiting for treatment.

Dr. Keenan will create a small access to the canal inside your root. He will clean out the infection and diseased tissue using rotary instruments that provide a thorough cleaning while still protecting the integrity of your tooth.

Once the infection is cleared from your canal, Dr. Keenan may prescribe medication to assist with healing. He will then fill your root canal with a rubber-like material and seal the tooth. After your root canal treatment is complete, we allow time for your inflammation to resolve and your body’s natural healing process to take over.

Post-Root Canal Therapy
When your root canal completely heals, we will recommend an appropriate dental restoration to protect and stabilize your tooth. Root canal teeth tend to be more brittle and need additional protection to prevent cracks. In some cases, a permanent filling may be enough to protect your tooth, but in most cases, a dental crown is a better option. Dental crowns completely cover your tooth, like a protective helmet. Because they encase your tooth, they provide extra support for chewing.

Are You Experiencing Dental Pain?

Contact our dental office to schedule an exam with Dr. Keenan. We will help determine the cause of your pain and provide you with options that restore your health and wellness.

If you are like most adults, you look in the mirror one day and discover that your once white smile is not quite as bright as it used to be. This happens much faster if you enjoy your daily triple latte on your way into the office or a glass of red wine with dinner.

Even if you don’t occasionally indulge, some of the healthiest foods we eat can take a toll on the whiteness of teeth – berries, dark greens, and some of the most flavourful spices all leave colour deposits on your teeth that can collect over time and darken your smile.

Stained teeth can make you feel self-conscious about showing off your teeth when you smile. At Keenan Dental, we can help!

Teeth Whitening – an Affordable Cosmetic Solution

One of the most budget-friendly ways to improve the appearance of your smile is with professional teeth whitening.

Getting started with teeth whitening is easy!

  • We recommend a dental cleaning for the best results
  • Our staff will take impressions of your upper and lower teeth
  • Our office fabricates custom whitening trays
  • Your kit supplies plenty of teeth whitening gel
  • We will take a starting shade to measure your results
  • You will receive instructions for use
  • We will take a follow-up whitening shade and show you the difference!

Be sure to keep your whitening trays – they will last a long time. If you need to touch-up your teeth, you can come by the office, where we offer additional whitening gel to go with your custom trays, so you can enjoy a whiter smile for a lifetime.

What about Over-the-Counter Products?

Over-the-counter teeth whitening products can provide some improvement to a stained smile, but they are not as effective without the customized whitening trays we provide. That means that the very front of your teeth may whiten, but the areas between your teeth go unbleached because whitening agents do not come into contact with them.

Another common problem with over-the-counter products is that they lack the potency of professional systems and therefore lack the dramatic results you can get at Keenan Dental.

When Teeth Whitening Works Best

Teeth whitening is safe for most healthy patients. For patients with recession or other conditions that cause sensitivity, we can provide advice and ways to desensitize your teeth, so that you can have a whiter smile comfortably.

For some deep stains, we may recommend additional treatment such as bonding or porcelain veneers to achieve the results you want.

The best way to find out if teeth whitening is right for you is to call our office and set up a consultation with Dr. Keenan. We are here to help you look and feel your best.  Contact our dental office today if you have any questions or if you’re ready to schedule an appointment. We accept new patients.

Just about everyone will experience a cavity at some point in their life. This doesn’t have to be a crisis, nor does it need to permanently alter your smile.

Regular dental visits will allow us to identify cavities early in their development – long before you ever feel a thing! Fact: most patients will not notice any symptoms after a cavity has formed. Detecting cavities early also allows us to provide conservative, simple treatments.

We like tooth-coloured fillings for several reasons, and so do our patients! When we fill your cavity with this putty-like resin, we can blend it to perfectly match the natural shade of your enamel. Even you probably won’t be able to find the filling later!

Additionally, tooth-coloured fillings bond directly to the tooth structure, which means that we can keep more of your own healthy tooth in place, a big improvement over old silver fillings, which required dentists to essentially carve a “hook” into the tooth structure to hold the filling in place. The finished product will be virtually invisible, allowing you to enjoy an increased level of protection without worrying about your look.

With countless years of experience and a wide variety of available services, you can trust Dr. Keenan and the rest of our experienced team to care for your whole family.

We’re here to help. Contact our dental office today if you have any questions or if you’re ready to schedule an appointment. We accept new patients.

Damaged teeth can be a real pain, especially if they affect the foods you can eat and your ability to smile. When your teeth sustain damage, we can repair your smile at Keenan Dentistry using high-quality dental restorations such as crowns and bridges. Restoring your teeth allows you to achieve greater confidence and balanced nutrition.

Dental Crowns to Protect Your Teeth
A dental crown is a restoration designed to stabilize a damaged or cracked tooth. You may have broken your tooth biting into something, in an accident, or due to deep decay. A dental crown becomes necessary when a filling does not provide enough support to prevent continued damage or tooth loss.
A dental crown covers your tooth from your gum line to the chewing surface. Since it covers your whole tooth, it absorbs some of the force from chewing and keeps your tooth from splitting beyond repair.

Dental Crown Treatment
We first remove any damaged tooth structure, including any decay. Next we can rebuild your tooth using composite, if necessary. This gives your crown a place to seat effectively. We will take an impression to create your dental crown and a temporary crown to hold you over until your porcelain crown arrives from our dental lab. Once we receive your permanent crown, we will permanently attach it to your tooth and make any final adjustments necessary to ensure a precise fit with your bite.

Fixed Dental Bridges
When you unexpectedly lose a tooth, you may have concerns about how to repair your smile. Fixed dental bridges fill in the gap left behind by your missing tooth and give you added confidence in your appearance. We meticulously match your dental bridge to your natural teeth so your smile is seamless and looks completely natural.

How Dental Bridges Work
In order to create a dental bridge, we need to place supportive crowns on the two adjacent teeth to anchor your false tooth, called a pontic. While dental bridges do not provide the same bone-preserving benefits of dental implants, they do keep your teeth from shifting.

Dental bridges are a good solution for our patients who want an alternative to dental implants.

Taking care of your dental bridge is important when protecting your investment. You can brush and floss a dental crown regularly. A dental bridge will require a little extra effort to keep it clean. You will need to use a small brush or specially designed floss to clean under your dental bridge in order to prevent gum disease.
