Clenching your jaw has a strong connection to getting headaches. While not all headaches are caused by jaw clenching, most people who do clench their jaws tend to get headaches and sometimes migraines. The primary joint in the jaw structure (the temporomandibular joint or TMJ) is connect to the nerve that is often involved in causing migraines, so clenching of the jaw can cause both migraines and tension headaches from clenching of the muscles around the neck and head.
In general, two types of jaw clenching are common bruxism, when one grinds their teeth or clenches their jaw excessively, and TMJD (temporomandibular joint disorder) which effects the jaw joint and may be caused by stress, injury, or a number of other dental causes.
Treatments can vary for jaw clenching, and will differ depending on which type of clenching you are experiencing and what is causing the clenching. To complicate things, sometimes jaw clenching can actually be caused by headaches that have a different cause – creating an endless cycle of headaches and jaw problems. This is why it is important to consult with a professional to determine the best course of treatment for your jaw concerns and headaches.
One of the simplest ways to try to stop headaches caused by jaw clenching is to become aware when you are clenching your jaw. Take note throughout the day if you are clenching your teeth, and make a conscious effort to relax your jaw. This can make a world of difference to your headaches. Over time, you may be able to build a habit of keeping your jaw relaxed throughout the day.
