A new 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 specially-constructed dental appliance which comfortably and securely places them between the lower and upper 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, the 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 and to sustainably release medications and odor-masking substances into the mouth,.

An intraoral discluding appliance for the prevention of trauma and temporomandibular joint syndrome. The device is a small intraoral device that is custom made for each individual patient. The device includes two discluding elements over the cuspid areas known as cuspid pads. The device is inserted in the mouth and retained against the upper or lower anterior teeth. Typically, the device will be retained on the upper anterior teeth but occasionally mandible placement is necessary. As the mouth is closed, the discluding elements contact the opposing cuspids and prevent the posterior teeth from touching. This effectively reduces parafunctional temporal muscle activity, eliminates trauma, and prevents bruxism. The device is removable and may be worn full time, but is typically removed at least during meals and for cleaning. Additionally, the device may be worn only part time, for example it may be used as a bedtime appliance.

Disclosed is a dental appliance composed of a thermo-plastic polymer with low compressibility, high toughness, and high tensile strength, with a low softening point. The appliance has perforations that enable it to be easily custom-fitted by the user or a health professional. The appliance begins as a generally U-shaped, unformed dental tray that is significantly thinner than existing dental appliances. Once fitted, the dental appliance provides superior protection against damage to the enamel of the teeth and abrasion of the teeth due to bruxism or other mechanism leading to biomechanical wear of dental surfaces. The perforations facilitate the custom-fitting process by allowing the user to suck air through the perforations, thus applying a negative pressure between the material and the teeth while the material is still soft and pliable. This enables a user or health professional to within minutes create a final product that rivals the quality and fit of an appliance made by dental laboratories using dentist made impressions.
