The most straightforward occlusal modification includes selective grinding (with the dental drill) of the enamel of the occlusal surfaces of the teeth.

All these methods cause irreversible changes to the oral structures. So, Dr. Adatrow does not prefer to use this method for the treatment of TMJ disorders. However, he will decide the best treatment based on your functionality and severity of the disease.
