The origin of bruxism is unknown. It involves clenching and grinding of one’s teeth while sleeping. This involuntary grinding of teeth harms teeth, gum, tongue, muscles and TMJ. It causes enamel wear and dental fractures if left untreated. It may be related to ATM syndrome. Other pathologies or signs associated with this pathology are headaches, migraines or muscle contractures. The compiling of a correct clinical history, patient exploration and radiological tests facilitate a diagnosis.
Treatment usually starts by fitting a dental splint.
In difficult to manage cases therapy with selective chemical microdenervation may be useful.
