Why to do if I bite the inside of my mouth? - Dr. Arundati Krishnaraj

If you have accidentally bitten the side of your check there may be slight ulceration which may be painful. Local application of an aesthetic gel may resolve the problem. If the check bite is because of your malalignment teeth or if you are wearing dentures for a long time and your teeth are worn out then the cheek may come in between the teeth and cause the cheek biting episodes. In the occurs the correction of the misaligned teeth or the change of dentures to a new one may resolves the cheek bite.
