Strange but True: Exercise Can Harm Your Oral Health

You’ve heard that exercise is good for your body and mind, and, well, that’s still true! However, if you don’t exercise carefully, you could actually end up harming your teeth and impairing your oral health. No doubt this claim sounds a bit far-fetched, so keep reading to get all the juicy details.

Sugar: It’s Probably in Your Sports Drink

There are plenty of good reasons to gulp down a sports drink while you’re working out. Many of them contain electrolytes, salt, and other ingredients that help you stay hydrated and prevent muscle cramps. The problem is that a lot of brands also have high sugar content, which can increase your risk of cavities when consumed frequently.

You don’t have to give up sports drinks entirely – just be sure to do your research and choose one that contains a minimal amount of sugar.

You Might Clench Your Teeth Without Realizing It

“Bruxism” is the word dentists use to describe habitual teeth grinding and clenching. Over time, the stress caused by bruxism can trigger TMJ disorders and prematurely wear down your enamel. The result? Chronic jaw pain and sensitive teeth.

Many patients grind their teeth at night without even realizing it, but studies show that certain workouts can have a similar effect. For example, if you lift weights, you’re likely tightening the muscles in your face, and could very well be clenching your jaw. To prevent this problem, ask your dentist for a custom mouthguard!

It’s Important to Have a Moist Mouth

Not many people know this, but saliva production is super important for your oral health. This gross, slimy substance actually helps protect your teeth from bacteria by essentially washing it away. Patients with chronic dry mouth are more vulnerable to the bacteria strains that cause cavities and gum disease.

Maybe you don’t have chronic dry mouth, but if you have a strenuous exercise routine, you probably breathe through your mouth, not your nose. Gulping in air like this can turn your moist oral biome into a bone-dry desert! Breathe through your nose when you can, or at least take frequent water breaks to help your mouth stay hydrated.

Exercise Mindfully and Visit Your Dentist

The oral health risks of exercise don’t negate the many physical and mental benefits it provides. But since athletes are disproportionately more prone to cavities and enamel erosion, it’s important to protect your mouth and teeth during your workouts! A few minor adjustments to your routine can really benefit your smile. Ask your dentist for more personalized tips, and you can avoid future dental complications.
