Tongue surgeryTongue surgery can help with bruxism by removing the frenulum, or the band of tissue that attaches the tongue to the floor of the mouth. This band of tissue can be very sensitive and can cause the tongue to be pulled back into the mouth when the teeth are clenched. Removing the frenulum can help to prevent the tongue from being pulled back into the mouth.

GrindcareBiofeedbackGrindCare is a breakthrough solution for people with bruxism. It measures precisely how much you grind your teeth, and can then reduce the grinding while you sleep. GrindCare works by registering muscle activity and sending a mild electrical impulse that interrupts the grinding.

The GrindCare App allows you to visualize grinding or clenching activity detected by the BUTLER® GrindCare® device during sleep and track improvements over time.

Data taken from the Grindcare ® manager software showing little effect of the Grindcare device in reducing parafunctional activity. Distribution and support stopped end of 2013.
