Bruxism (teeth grinding/clenching)

Bruxism is the medical term for teeth grinding. We can include clenching in this category too. It is unknown how many people grind or clench their teeth at night, but it is a significant percentage of our population.

Why do people grind or clench their teeth at night?

It is also not clearly understood why people grind or clench their teeth at night. For some, it is genetic. For many people, stress and anxiety from daily life manifests as tense jaw muscles, which then translates into muscle hyperactivity at night. There are some medical conditions and also some medications that can trigger these muscle spasm as well.

What are the effects of nocturnal bruxism (teeth grinding at night)?

After being active all day, involved in talking and chewing, and possibly clenching, your jaw muscles need a break at night, like any other muscle. However, if you are clenching or grinding your teeth at night, then your jaw muscles are not getting a break. They are continuing to be active, and they will become perpetually sore. Patients suffering from nocturnal bruxism experience headaches and jaw tightness. The repetitive pressure on the joints can also cause joint inflammation, which can lead to TMJ clicking and pain. And of course, if you are constantly grinding your teeth against each other, you will eventually chip your teeth and wear them down.

How is nocturnal bruxism treated?

Nocturnal bruxism is not a conscious phenomenon, and you can’t stop on your own. Usually, a multi-pronged strategy designed by your doctor will help you control this habit. It consists of lifestyle modifications during the day, wearing a night guard at night, and possibly taking muscle relaxants at night if necessary. Sometimes, if this isn’t enough, your doctor will inject the stubborn muscles with Botox® or other similar medications to force them to relax and to give you some relief.
