Bruxism (Teeth Grinding) - What you need to know

Bruxism, commonly known as teeth grinding, is a condition considered as movement disorder of the jaw.

Grinding or clenching of teeth usually characterises this condition.

Even though the cause of bruxism is unknown, experts suggest that psychological stress plays a major role.

According to  recent studies available, women are more affected than men.


It is estimated that between 20%-30% of  the adult population are affected and approximately 15% of kids have a similar condition.

As mentioned earlier, treatment of bruxism depends on the severity of the condition.

Solutions may vary from case to case.  Occlusal Splint (night guard) is the most common solution dentists can provide.

This dental device is worn at nighttime to protect teeth while sleeping.

There are also various jaw exercise and therapy options that can be implemented.
