This is called bruxism.. slowly u will grind the outer hardest layer enamel , and after than dentin wears off rapidly. This is lead to collapse in your overall bite and damage all your teeth severly and will directly affect your temporomandibular joint and cause pain . To prevent further damage , ask your dentit for a Nightgaurd . If there is some damage already , reconstruction or capping few teeth may be required to regain the original bite . In severe cases , full mouth rehabilitation is adviced. But anyday prevention is better and less expensive than cure.

It will lead to MPDS in future!
