Consistent physical exercise is one of the best gifts you can give yourself. Whether you’re focused on your physical or mental health, research shows it offers a laundry list of benefits. But there’s always a catch, right? While forcing yourself to get to the gym might sound unpleasant, dental issues caused by exercise can actually be a much bigger headache (or rather, toothache).

Exercise & Your Oral Health

What makes exercise potentially perilous for your teeth?

  • Grinding It Out: Many people unconsciously clench their jaw and grind their teeth while working out, particularly when lifting weights. This can lead to sensitivity and even cracks/breakage over time.
  • “Is It In You?”: Most sports drinks are LOADED with added sugar to offset the sodium needed to help replenish electrolytes lost as you sweat. They are essentially the same as drinking a soda!
  • Dental Injury: Whether you like to run, lift, or just play pickup games with your friends, tripping or receiving a sudden impact can result in loose or even knocked-out teeth.

How to Keep Fit (& Smiling)

Thankfully, all of these issues can be easily mitigated with tiny adjustments you can start doing before your next set.

  • Be Mindful: Try to notice if you’re tensing your jaw when exercising. Simply observing this can allow you to relax, which will probably make it easier to push yourself!
  • Water is Your Friend: It’s wise to avoid most popular sports drinks and opt for plain water if you need hydration. If you frequently work out when it’s warm, adding just 1/8th of a teaspoon of salt to your water can help if you need to replenish electrolytes.
  • Wear a Mouthguard: Play sports or run on concrete regularly? It’s recommended you wear a custom mouthguard. This will save you a visit to the dentist in case you’re struck by an errant ball or accidentally trip.

For that last tip, it’s best to get a mouthguard made by your dentist, as it will not only be more comfortable and provide better protection, but also make it easier to breathe compared to a generic guard.
