Can taste aversion prevent bruxism?

The first part of this note sketches a biofeedback modality for the treatment of bruxism. A mildly aversive, safe liquid is inserted into, and sealed in, small, bilaterally sleeved, polyethylene capsules. Two capsules are attached to a simple dental appliance that comfortably and securely places them between the lower and upper back teeth. The appliance and capsules are worn at night or at other times when bruxism is suspected to occur. Whenever a sleeping or an awake patient attempts to brux, one or both capsules rupture and the liquid is released into the mouth. The liquid then draws the patient's conscious attention to, and forestalls, any attempt of teeth clenching or grinding. Variations of the method and device can be used to diagnose bruxism. The second part of this note describes the long-term application of this taste-based approach to one chronic bruxer.
