Why do my teeth hurt when I exercise?

Have you ever felt sensitivity in your teeth and gums during or after exercise?

You are not alone! Here’s what may be causing the sensitivity:


Gingivitis can lead to discomfort during exercise. Gingivitis occurs when bacteria gets trapped in your gums, and your body produces an inflammatory response making your gums swollen and sore.

When you exercise, your heart pumps faster to supply your body with oxygen. Unfortunately, if you have gingivitis present in your mouth, this will mean more blood is also being supplied to inflamed areas which can lead to soreness and discomfort.


When exercising, your body can go into overdrive to provide you with the needed energy. Sometimes this can lead to involuntary jaw-clenching. Even if you don’t realize it, the forces applied by your teeth during clenching can leave your gums feeling sore and jaw muscles tensed.

Sinus Congestion

If you are an allergy sufferer or are fighting a cold, chances are your sinuses are congested. Built up pressure in your sinuses can radiate to the oral cavity and leave you with sores gums and teeth. When exercising, especially outdoors, sinus pressure can cause the pain you experience after a workout.

Just remember that these are just some of the reasons you can be experiencing pain in your mouth after exercising. Be sure to consult your dental care professional for a more thorough diagnosis and treatment plan options.


As always, keep smiling!
