for the condition can include removable appliances, replacing missing teeth, moving teeth, adjusting the bite, filling gaps between teeth, etc. There is no one solution that is right for all cases. Sometimes a plastic mouthpiece is used to prevent clenching or grinding that is contributing to the problem or to realign the bite. TMJ can be very discomforting if left untreated. Prolonged teeth grinding, or bruxism, causes enamel to wear off the teeth and expose dentin. This material is softer than enamel and more susceptible to decay. Sensitivity to hot and cold food or drinks may also develop from excessive teeth grinding. If you suspect you may have TMJ, come in for a consultation.
