Woman with a headache and jaw pain.

Are you one of the millions who suffer from chronic headaches? Even if you have tried over-the-counter pain relievers and other headache remedies, recurring headache pain and discomfort can derail your day, often affecting your work, family, and more.

But did you know that the root cause of your recurring headaches might be hiding in your mouth? Sometimes, seemingly unrelated dental health issues can be a headache trigger.

Understanding Headaches

Headaches are a common and often debilitating problem that can affect anyone, are any age. They are characterized by pain or discomfort in the head or upper neck region and can vary in intensity from a mild, nagging ache to severe, throbbing pain.

Headaches can be classed into various types, including tension headaches, migraines, sinus headaches, and more, each with its unique set of symptoms and triggers. While not all types of headaches are well understood, we do know that most headaches result from issues with the vascular, muscular, and other structures in the head, face, jaw, or neck areas.

Dental Health and Headaches

Occasional headaches are a normal part of life, however, chronic or frequent headaches shouldn’t be ignored, as they may indicate underlying health issues, including those related to dental health. Understanding the nature of headaches and their potential causes is helpful for effectively managing and preventing them.

Bruxism and Tension Headaches

One common dental issue that can lead to headaches is bruxism, which is the clenching or grinding of teeth, often during sleep. This constant pressure on your teeth and jaw muscles can result in tension headaches. Pain from this area can radiate from your jaw to your temples, causing discomfort that lingers throughout the day.

TMJ Disorders and Migraines

Temporomandibular joint (TMJ) disorders are another dental problem associated with headaches. The TMJ is responsible for the movement of your jaw, and any dysfunction in this joint may be a possible trigger for severe headaches. TMJ-related headaches can often be misdiagnosed as migraine. It is also thought that, for patients who do suffer from migraine headaches, TMD can be a trigger.

Bite or Misalignment of Teeth

In some cases, problems with your bite alignment or misaligned teeth can contribute to the development of headaches. When your upper and lower teeth don’t fit together correctly, it can result in added stress on the jaw muscles, leading to tension headaches or even migraines.

The Impact of Poor Oral Health

When dental issues are left unaddressed, they can escalate and lead to chronic headaches. Tooth decay, when left untreated, can progress and lead to cavities or even tooth abscesses. The pressure and pain from these infections can radiate to your head, resulting in sinus headaches or tension headaches.

Similarly, gum disease can cause inflammation throughout your body. This systemic inflammation can trigger headaches, making it crucial to address gum health for your overall well-being.

Proactive Measures for Dental Health and Headaches

Now that you’re aware of the connection between dental health and headaches, here are some steps you can take to prevent or alleviate these issues:

Stress Management

Because stress is a common cause of bruxism and TMJ disorders, incorporating stress-reduction techniques into your daily routine can help prevent dental-related headaches.

Proper Oral Hygiene

Brushing and flossing regularly, along with regular professional cleanings, are the best ways to prevent tooth decay and gum disease. A healthy mouth is less likely to contribute to headaches.


If you suffer from bruxism, your dentist may recommend you wear a custom mouthguard to protect your teeth and jaw from grinding, ultimately reducing the risk of tension headaches.


If your headaches are related to bite or alignment issues, your dentist can potentially recommend orthodontic treatments such as Invisalign to correct the issue, potentially alleviating headache symptoms.


Botox has been shown to be an effective treatment for TMD and for chronic migraine. And, perhaps not surprisingly given the connections we’ve discussed in this article, dentists are often trained and qualified to give Botox injections for chronic pain.
