What Are The Causes Of Bruxism?

The primary cause of bruxism is not clear. However, bruxism is causally related to dental occlusion. Unfortunately, there’s little proof to support it. In some studies, they showed that occlusal interference may not cause bruxism.

This dental condition can happen to anyone. Children may experience it after their first set of teeth appears. Then, bruxism occurs again when their permanent teeth begin to show. Once their adult teeth have fully erupted, grinding of their teeth may also stop.


It is one of the common causes of bruxism. You may not notice it but you may be grinding your teeth while you’re angry or anxious. In some patients, brain activity and heart rate may increase before bruxism occurs. Thus, CNS may play a role in it.

If you have facial muscles spasm while sleeping, you may tend to grind your teeth. Then, if you have missing teeth or if your teeth are crooked, then these, too, could be a factor.

It could also be an effect of medications, like antipsychotics and antidepressants. If you have Huntington’s disease or other neurological conditions, then you are likely to suffer from it.

This condition is common in childhood. Although it may still occur in an older population, the rates are somehow lower than in the younger population. In other words, your bruxism may go away when you get older.

How to prevent bruxism?

Even though bruxism doesn’t have an exact cause, there are some ways to prevent and treat it. You can start by listing your symptoms. Then, tell your dentist about them during your dental appointment. Your dentist may perform a dental examination to know more about your symptoms. After performing the examination, he can figure out the cause of your bruxism.

In most cases, the dentist will recommend a mouth guard. It will not treat bruxism. However, it alleviates any damage that may have caused by grinding your teeth. Your dentist may also perform a dental procedure that can correct problems to your teeth alignment.

Stress reduction techniques may also help. Keep in mind that stress is one of the most commonly known causes of teeth grinding. You may not always need a professional counseling, although you can benefit from it. But there are various ways to manage it.

One of them is through exercise. Physical activities, like walking, jogging or running can release endorphins that may help in relieving your stress. If you’re anxious about something, you may try listening to music or have a warm bath. They are all helpful in this situation.

Your work may be to blame for your stress. Thus, make sure to know how to approach your work-related issues properly.

It is ideal to talk to your dentist about your teeth grinding. He may also recommend a mouthguard. But it has to be customized to properly fit your mouth. Otherwise, it’ll be useless to wear it. Then, make sure that you start relieving your stress and get rid of any negative thoughts or emotions.

This issue has to be mitigated as teeth grinding can cause enamel erosion, causing your teeth to be more vulnerable to tooth sensitivity.
