When Is a “Cavity” Not a Cavity?

April 14th, 2021

Is this a trick question? After all, you and your family probably already know quite a lot about cavities:

  • It all begins when bacteria-filled plaque sticks to teeth and starts to attack enamel. How?
  • Because the bacteria in plaque use the sugars and other foods we eat to produce acids.
  • These acids gradually weaken teeth by dissolving minerals that help make up our enamel (a process called demineralization).
  • Over time, a hole, or cavity, develops in the tooth surface.
  • Left untreated, bacterial decay can spread to the inside of the tooth, creating a more serious cavity.

Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough might discover an unexpected cavity at a regularly scheduled dental exam at our Kingston, ON office, but there are also some symptoms that should have you calling for an appointment. A cavity can cause sensitivity when eating something hot or cold, or it can be painful, or you might even notice visible discoloration or damage to the tooth surface.

So, if your child has any of these symptoms, it’s a cavity, right? It might be—but it might not. Sometimes, because the symptoms are similar, what we suspect is a cavity is really enamel erosion.

The bacteria-created acids weaken enamel. But it’s not just bacteria that subject our teeth to acids. Acidic foods are one of the leading causes of tooth erosion.

And while we expect damage from a lifetime of acidic foods and beverages to catch up with us as we age, the fact is that erosion is becoming a problem even for young children. How is this possible? Let’s look at some food chemistry.

Our normal saliva pH level is around a 7, which is neutral. Any number lower is acidic; any number higher is alkaline. Acidic foods have a low pH (the pH of lemon juice, for example, measures between 2 and 3), and can reduce our normal, neutral pH level. When saliva pH levels drop to 5.5 or lower, tooth enamel starts to demineralize, just as it does when exposed to the acids from oral bacteria.

Regularly snacking on citrus and other acidic fruits, fruit juices, flavored drinks, sour candies, and other acidic foods can cause enamel erosion. Especially erosive are sports drinks, energy drinks, and colas, because they contain some combination of citric acid, phosphoric acid and/or carbonation.

So, when might you suspect enamel erosion? Your child might be sensitive to hot or cold foods, or feel pain, or even have noticeable enamel loss or pitting. Even though these symptoms may not have been caused by plaque and bacteria, acidic erosion from our diets leaves weakened enamel just as vulnerable to cavities and decay.

How to avoid erosion?

  • Serve acidic foods sparingly, or as part of a meal. This helps our saliva pH stay in the neutral zone.
  • Balance acidic foods with low-acid choices to neutralize acids and restore a normal pH balance. For example, mix those acidic berries with a banana.
  • Use a straw! These are not only fun, but this simple solution keeps erosive drinks from bathing young teeth in acids.
  • Encourage your child to drink water instead of an acidic beverage, or drink it afterward to rinse acids away. The pH of pure water? A perfect, neutral 7. And by using tap water instead of bottled water, you’ll be providing fluoride, which helps strengthen enamel.
  • What about brushing right after eating or drinking something acidic? Ask Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough if your child should rush for the brush. We may recommend waiting 30 minutes or so after an acidic treat to give the teeth time to remineralize. Otherwise, brushing might cause more wear and tear on enamel.
  • Finally, while foods are often the source of acid erosion, medical conditions can cause erosion as well. Talk to us about ways to minimize erosion while addressing these medical needs.

Be proactive. Ask your Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough about healthy drinks and snacks for healthy teeth. Make sure to keep on top of brushing and flossing, and stick with fluoride toothpastes. And visit our Kingston, ON office regularly for exams and cleanings.

There’s really no trick to it—preventing enamel erosion helps keep your child’s teeth structurally strong and cavity-free for a lifetime of beautiful and healthy adult smiles.

There’s an App for That!

April 7th, 2021

Kids today are more tech-savvy than ever before. Even young children use computers, tablets and smart phones to make learning about their world more accessible and more enjoyable. And with the enormous variety of apps geared to childhood education, it comes as no surprise that you can download an app to encourage your children to learn about—and celebrate—their dental health.

What kinds of apps are available for your child?

Happy Brushing!

Children’s apps can offer helpful advice for learning effective brushing and flossing habits that will last a lifetime. Some of the apps for young brushers include:

  • Age appropriate instructions for proper brushing technique
  • Two minutes of carefully chosen songs or stories to keep them brushing the recommended amount of time in an entertaining way
  • Reminders to replace those little toothbrushes—every three months, please!
  • Educational games and stories to teach effective dental habits and tooth-healthy food choices.

The best apps not only provide lots of important information for keeping young teeth and gums their healthiest, but make learning fun with rewards such as badges, stars, games, or simply plenty of positive encouragement.

Time for the Tooth Fairy to Appear?

Losing a tooth is an important event for many young children. If you’re a fan of the Tooth Fairy, there are apps that can provide some reassuring fun while your child waits for that first loose tooth to finally come out. Tooth Fairy apps offer a wide variety of activities, including:

  • Tooth Fairy voicemails to report a loose or lost tooth
  • Tooth Fairy diaries to record lost teeth—and save photos of the adorable smiles that result
  • A video of an animated Tooth Fairy fluttering around your child’s pillow on the big night
  • A Tooth Fairy alert for forgetful Tooth Fairy assistants.

Apply the Latest in Brushing Technology

If you’ve decided that an electric toothbrush is the best brush for your child, many of the products available today come with their own apps. What can these apps do?

  • Let children know if they’ve brushed long enough
  • Alert them when they’re brushing too hard, which is not good for young gums and enamel
  • Some apps even provide a map of the mouth and teeth that lets children know just where they’ve brushed, in case they tend to neglect a few spots regularly.

Keep Those Appointments

Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough and our team are here to help keep your child’s teeth healthy.

Heading Off to College? Maybe It’s Time to Graduate to an Electric Toothbrush!

March 31st, 2021

Your trusty manual toothbrush has been with you from pre-school through high school—well, obviously not the same manual toothbrush, because that would be seriously unhygienic—but it’s the kind of toothbrush you’re used to and comfortable with.

Now, though, you’re off to college, and your lifestyle will be changing. Late night study sessions complete with study session snacks. Getting caught up in a project and making dinner from dorm vending machines. Grabbing fast food on the way to the practice field, or work-study job, or evening class. You get the point—meals can be hectic, unscheduled, and less than tooth friendly.

Maybe it’s time to consider an electric toothbrush. After all, anything that can make your life easier and more efficient during busy college days deserves a spot in your dorm room.

  • Electric Brushes Are Effective

The most important reason to switch to an electric toothbrush is its effectiveness. Several studies have shown that regular use of an electric toothbrush leads to a marked reduction in plaque, that bacteria-filled film which sticks to the teeth and leads to cavities and gingivitis. And it’s really no surprise that an electric brush can out-perform a manual brush.

Electric toothbrushes offer several design options, from oscillating/rotating brushes to oscillating/rotating/pulsating models to brushes using sonic vibration technology. What these technologies all have in common is the ability to remove plaque far more efficiently than we can on our own, because electric brushes provide the equivalent of thousands and even tens of thousands of brushstrokes per minute, compared to the hundreds we can achieve by hand.

You know by now what your brushing habits are like. If you tend to be a bit cavalier with your brushing and flossing, make sure you set yourself up for success. Because you have better things to do during semester breaks and summer vacations than visiting Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough!

  • Electric Brushes Can Make Life Easier

Several of today’s electric brushes come with options designed to do more than simply remove plaque. They can let you know if you’ve brushed for the recommended two minutes, alert you if you’re brushing too hard, and even remind you when it’s time to replace the brush head.

Want more from your electric brush? Some models offer apps that can map out just where you’ve brushed, in case there are a few spots that often get overlooked. Or provide different brushing modes for daily cleaning, deep cleaning, whitening, and more. Or come with a travel case that can recharge while you’re busy exploring the world—or going home for a visit.

In the end, it’s up to you. Do some independent study and research the toothbrushes that will give you the best results for your individual brushing habits. You might not need or want a brush with all the technological bells and whistles.

If you’re comfortable with your manual brush and you get good grades when you visit our Kingston, ON office, stick with it. But if you think you might benefit from the ease and efficiency of an electric toothbrush, if an electric toothbrush makes your teeth and gums healthier and your smile brighter, that’s an extra credit project worth pursuing.

What causes tooth loss?

March 24th, 2021

When children lose baby teeth, it’s a time to rejoice. But when adults suffer from tooth loss, it may be a sign of a serious problem. That’s when it’s time to give us a call at Cataraqui Dental Centre.

What are the reasons for missing teeth?

The loss of permanent teeth can occur for a variety of reasons, ranging anywhere from hereditary factors to tooth decay to traumatic injury. Here are the following reasons why adults suffer tooth loss:

  • Gum disease: The number one cause of lost teeth in adults is gum disease, also known as periodontal disease, an infection of the structures that support the teeth. Once gum disease reaches and destroys the alveolar bone, the teeth begin to loosen and will eventually fall out or need to be extracted.
  • Tooth decay: If cavities are left untreated, they can destroy tooth structure as well as cause infection in the supporting bone.
  • Tooth injury: An injury can either knock out a tooth immediately or cause damage to the root or pulp that will later require extraction. We recommend using a mouthguard if you play sports.
  • Tooth fracture: A fracture in a tooth is often caused by teeth grinding, or what Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough and our team call bruxism. A crown may be the answer, but depending on the location of the crack or fracture and how deeply it extends, the tooth may not respond well to repair with a crown and may need to be extracted instead.

What are the risk factors for tooth loss?

  • Poor oral hygiene: Patients who only occasionally brush or floss their teeth are more likely to develop tartar, plaque buildup, and other bacteria that cause decay.
  • Not visiting the dentist: Seeing Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough every six months for a cleaning and checkup prevents any developing oral health issues, as well as ensures that plaque and tartar do not build up over time.
  • Smoking: Smokers and users of smokeless tobacco are more likely to develop periodontal disease that can cause tooth loss. If you are a smoker it is crucial to visit us on a timely schedule.
  • Various health conditions: Patients with high blood pressure, diabetes, rheumatoid arthritis, and other chronic health issues are more likely to suffer from gum disease.

Scheduling an appointment with Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough at our Kingston, ON office will give you an accurate diagnosis and a variety of treatment options. It’s important to know that periodontal disease is “silent,” meaning you will not always experience pain as a signal of infection. When caught early, treatments are usually successful.
