Have you ever been out for a run, feeling energised and focused, only to be interrupted by an unexpected pain in your teeth? It can be frustrating when something as simple as running causes discomfort in a place you wouldn’t expect – your mouth.

If you’ve ever wondered why your teeth hurt when running, you’re not alone. At Avenue Dental Practice, we frequently see patients who experience tooth pain during physical activity and offer solutions that can bring lasting relief.

In this blog, we’ll explore the reasons behind tooth pain during exercise and what you can do about it.

There are several reasons why you might feel pain in your teeth while running. Some are related to underlying dental conditions, while others could be due to external factors like the weather or your running technique. Let’s break down some of the most common causes:

One of the most common reasons for tooth pain while running is sinus pressure. The sinuses are located close to the upper teeth, and when they become inflamed or filled with mucus (as with a cold or allergies), they can press on the nerves of your upper teeth. This pressure may be exacerbated during running because the increased blood flow and movement cause the sinus cavities to swell slightly, resulting in discomfort or pain in the upper teeth.

Solution: If sinus pressure is the culprit, treating the underlying sinus issue (such as with decongestants or allergy treatments) can often alleviate the tooth pain. It’s also worth running in cleaner, less polluted environments if pollution or allergens are contributing to your sinus issues.

Many people unconsciously clench their jaws when concentrating or engaging in physical activity. This habit, called bruxism, can lead to tooth sensitivity and pain over time, particularly if it’s combined with the impact and jarring motions of running. The pressure from clenching can cause strain on the teeth and surrounding muscles, leading to pain that may flare up during a run.

Solution: If you suspect bruxism is the cause, try to stay aware of your jaw position during runs and consciously relax your muscles. A custom mouthguard from your dentist may also help by reducing the pressure on your teeth during exercise.

If your teeth hurt when running, it may be due to general tooth sensitivity. Sensitivity can occur when the protective enamel layer of your teeth has worn down, exposing the softer dentin underneath. Changes in temperature – such as breathing in cold air during a run – can cause sharp pain or discomfort in exposed areas of the teeth.

Solution: Using toothpaste specifically designed for sensitive teeth can help reduce discomfort. You might also want to avoid running in very cold weather, or use a scarf or mask to protect your mouth from cold air.

Sometimes, tooth pain during running can be a sign of more serious dental problems like cavities or tooth decay. Cavities weaken the tooth structure, making it more susceptible to pain, especially when there’s added pressure or impact from running. Decay that reaches the nerves of the tooth can cause pain during any form of physical exertion, including running.

Solution: If you suspect tooth decay, it’s important to see your dentist as soon as possible for a thorough examination. At Avenue Dental Practice, we offer comprehensive check-ups and treatments to address cavities and prevent further discomfort. Prompt treatment, whether through fillings or other dental procedures, can help preserve your oral health and stop the pain from worsening.

Gum disease is another potential cause of tooth pain during running. In the early stages, it might not cause much discomfort, but as it progresses, inflammation of the gums can affect the teeth and supporting structures. The movement and blood flow increase during running can make this pain more noticeable.

Solution: Regular dental check-ups and cleanings are crucial for preventing and treating gum disease. If you’re already experiencing pain, a deep cleaning from your dentist and improved oral hygiene habits can help manage the condition.

Now that we’ve covered the common causes, let’s look at some practical steps you can take to prevent tooth pain when running:

1. Stay Hydrated: Dehydration can contribute to mouth dryness, which might increase the likelihood of discomfort. Drinking plenty of water before, during, and after your run can help keep your mouth hydrated and reduce irritation.
2. Use a Mouthguard: If clenching or grinding is an issue, consider wearing a custom mouthguard. It can help protect your teeth from the impact and pressure associated with running.
3. Warm Up Your Body and Mouth: If you’re running in cold weather, warm up your muscles and your mouth. Try breathing through your nose or wearing a scarf over your mouth to reduce the direct contact of cold air with your teeth.
4. Maintain Regular Dental Check-Ups: Keeping up with regular visits to the dentist will help you stay on top of any potential issues, like cavities or gum disease, before they become a problem. If you’re in the area, book an appointment with Avenue Dental Practice, where our experienced team will ensure your teeth and gums are healthy, so you can focus on your fitness without distraction.
5. Adjust Your Breathing: If you tend to breathe through your mouth while running, switching to nasal breathing can help reduce the exposure of your teeth to cold air and lessen sensitivity.

Tooth pain while running can be a frustrating experience, but understanding the potential causes can help you take the right steps to alleviate it. Whether it’s due to sinus pressure, tooth sensitivity, or something more serious like tooth decay, there are solutions available. If you continue to experience pain despite making adjustments, it’s always a good idea to consult with your dentist. Your dental health is crucial not just for your comfort but for your overall well-being. After all, a healthy mouth can contribute to a healthier, happier you – both on and off the track.
