Carbs and Cavities

September 14th, 2022

The Good News

Carbohydrates are one of the body’s essential macronutrients (along with protein and fat). We use carbs to convert the food we eat into energy. How does this work? It’s a sophisticated process:

  • Carbs break down into sugars as we digest them
  • Sugars are absorbed into our bloodstream
  • The pancreas releases insulin when blood sugar levels rise
  • Insulin enables sugars to move from our blood to our cells
  • Cells throughout the body use this sugar for energy.

Without the necessary amount of carbohydrates, our bodies lose a vital source of energy. So, why are carbs a dental concern?

The Bad News

Some foods immediately begin breaking down into sugars in the mouth. Sugars are a favorite food source for the oral bacteria that form plaque. They use this sugar to produce the acids that weaken our enamel and lead to cavities. And the more often we eat these foods, and the longer they remain in the mouth, the more damage our enamel suffers.

But there’s a silver lining! We can be healthier physically and get a jump on preventing damage from sugary treats by becoming more discriminating in our choice of carbs and timing our indulgences wisely.

Good Carb/Bad Carb

Unprocessed, complex carbohydrates are found in foods like whole-grain breads and cereals, legumes, and vegetables. They contain the vitamins, minerals, and fibers which are lost when foods are refined. They are composed of larger, more complex molecules, and so they break down gradually for sustained energy.

Some simple carbohydrates break down into sugars more quickly, but also offer important vitamins, minerals, and fiber. Fruits and dairy products, for example, are an important part of a balanced diet.

But some carbs are not pulling their nutritional weight. Refined sugars (think candies, desserts, and sodas) and refined starches (white bread and rice, potato chips, pastries) break down quickly into sugar in the mouth. Worse, many of these foods tend to stick around. Sticky sugars and sticky starches cling to our enamel and hide between the teeth and in the crevices of our molars. Not only do these treats provide a sugary feast for acid-producing bacteria, they take their time doing it!

So, What to Do?

If you have a diet filled with healthy carbs (whole grains, fruit and vegetables, legumes, dairy products), you’re already on the right track. Kudos! But does this mean no desserts? Ever?

No! We all need a cookie sometimes. But you can decrease the chance of enamel damage by interrupting the carbs to cavities cycle.

First, if you are indulging in a rich dessert or some salty chips, better to do it as part of a meal. When you eat a full meal, your body produces more saliva. Saliva not only helps wash away food particles, it also helps neutralize the acids that damage enamel.

Secondly, if you eat simple carbs and sugars all day, your mouth and teeth are being treated to acids all day. If you are going for a snack, there are many great options that don’t use refined sugars and starches. Think fruit smoothies (with a big dollop of vegetables) or whole-grain crackers with hard cheese instead of a can of soda and a bag of pretzels.

Carbs aren’t really bad, they’re just misunderstood. Talk to Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough at your next checkup at our Kingston, ON office for ideas for the best carbohydrate choices for healthy metabolisms and healthy smiles!

Electric or Manual Toothbrush: Why It Does (and Doesn't) Matter

September 7th, 2022

You live in the golden age of toothbrushes. Until a few decades people used twigs or brushes made from animal hair to clean their teeth: not very soft and none too effective.

Now, you have a choice of manual brushes with soft, medium, or hard bristles. Or you might choose to go with an electric toothbrush instead.

Have you ever wondered whether manual or electric brushes provide better cleaning? Actually, they both do the job. The key is to brush and floss every day, regardless of the kind of brush you prefer.

At our Kingston, ON office, we like to say the best brush is the one you'll use. So if you prefer manual, go for it. If you prefer electric, turn it on.

Both types have their advantages but both types will get the job done as far as removing plaque.

Electric Toothbrushes

  • Provide power rotation that helps loosen plaque
  • Are great for people with limited dexterity due to arthritis or other problems
  • Are popular with kids who think the electric brushes are more fun to use
  • Can come with variable speeds to help reduce pressure on sensitive teeth and gums

Manual Toothbrushes

  • Can help brushers feel they have more control over the brushing process
  • Allow brushers to respond to twinges and reduce the pressure applied to sensitive teeth and gums
  • Are more convenient for packing when traveling
  • Manual brushes are cheaper and easier to replace than the electric versions.

In many ways, the golden age is just beginning. There are already phone apps available to remind you to brush and floss. New apps can play two minutes worth of music while you brush, help you compare the brightness of your smile or help explain dental procedures. Maybe someday we’ll even have programs that examine your teeth after brushing and identify spots you might have missed.

DIY Teeth Whitening

August 31st, 2022

We all want our best and brightest smiles, and today there are many options we can explore at home to make those beautiful smiles a reality. Whether it’s healthy habits, a healthy diet, whitening toothpaste, or do-it-yourself home products, we have golden opportunities to achieve whiter teeth.

  • Healthy Habits

Proper brushing is the first step in keeping your teeth stain-free. You should devote at least two minutes twice a day to brushing, being careful to cover the areas between and at the base of teeth, where plaque you miss can form visible tartar. Ask us about the most effective brushing techniques. And please, don’t smoke. Smoking is one of the worst offenders when it comes to discoloring teeth. If you are a smoker, quitting at any point in your life will make a big difference in the whiteness of your smile—and your lasting health!

  • Healthy Eating

We all know red wine, coffee, and tea cause some of our worst enamel stains. Acidic drinks such as sodas and citrus beverages can cause even more problems by eroding tooth enamel, exposing the yellowish dentin underneath. Moderation and rinsing with water can help prevent damage. But we have some dietary allies as well! Crunchy foods like apples, carrots, and celery provide a mild scrubbing effect. Dairy products such as milk, cheese, and yogurt strengthen enamel. Fruits such as strawberries and pineapples, studies suggest, contain enzymes that are natural stain removers. While no one food takes the place of brushing or cleaning, a healthy diet and a healthy body enhance any smile.

  • Brushing with a Whitening Toothpaste

Toothpastes are available which can remove some surface stains, and which can keep teeth their whitest after a professional whitening. They won’t penetrate the enamel surface or change the natural color of your teeth. If these toothpastes are going to work on discolored tooth surfaces, you will usually see results within a few weeks.

  • Over-the-counter (OTC) Whitening Kits

These products provide a peroxide-based gel that can be applied in a tray or with strips. If you choose a tray application, make sure trays fit properly so sensitive mouth and gum tissue is not irritated. If you decide on strips, always make sure all of the tooth surface is covered to avoid uneven whitening. These kits have more powerful whiteners than toothpastes, and so you might see better results, but tooth and gum sensitivity can be a problem.

While all these whitening methods can be helpful, there are some circumstances when a professional whitening is best. Professional gel whiteners are more powerful, and can help eliminate darker stains that OTC products can’t remove. We can make sure sensitive gum and mouth tissue is protected from bleaching agents. And, if you are on a deadline, we can provide a much faster result. Some conditions, such as deep stains caused by trauma or medication, or darker-colored caps, veneers, and crowns, require more than whitening, and we are happy to present options for those situations.

If you have any questions or concerns about whitening your teeth, please give our Kingston, ON office a call. Whether it’s advice on how to brush or how to quit smoking, discussing the effects of foods and drinks on our teeth, suggesting OTC whitening products, or providing a professional whitening, Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough and our team are happy to help you achieve your best and brightest smile!

Medication Can Lead To Xerostomia in Women

August 24th, 2022

Xerostomia, otherwise known as dry mouth, can be a side effect of many common medications. Drugs used for blood pressure, birth control, antidepressants, or cancer treatments may cause the dry mouth problems you’re experiencing. When you have dry mouth, you’re more likely to experience tooth decay and an increased risk of developing periodontal disease. Medication can sometimes be the cause of dry mouth in women, and lead to an increased amount of cavities.

You may not develop a cavity for years, but suddenly find more than one when you’re on medication for several months. This is due to there being less saliva in your mouth, which normally prevents bacteria from flourishing. When there is a lack of saliva flow, your mouth will be more likely to host tooth decay and be more prone to gum disease.

You may not notice it, but birth control can lead to inflammation of the gums and bleeding because of dry mouth. The condition can also emerge if you’ve undergone cancer treatments such as radiation, because your saliva glands may be damaged in the process.

Boosting saliva production is critical for treating xerostomia. Many over-the-counter saliva products are designed to help manage dry mouth. For women with severe cases of dry mouth and decay, we may recommend in-home fluoride treatments that offer extra enamel protection. This can come in the form of fluoride trays, prescription toothpaste, or a special fluoride rinse.

Other ways to relieve dry mouth include chewing sugar-free gum, limiting caffeine intake, avoiding mouthwashes that contain alcohol, sipping water regularly, using a humidifier at night, and stopping all tobacco use.

If you believe you may be experiencing symptoms of dry mouth, contact our Kingston, ON office to schedule an appointment with Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough. It’s wise to take medications that have been prescribed by your doctor, but it’s also smart to watch for any side effects. If you think a medication is causing you to have dry mouth, let’s figure out how to manage your symptoms as a team!
