BOTOX® Injections. In some people with TMJ disorder, injecting Botulinum Neurotoxin Type A (Botox) into the jaw muscles can relieve bruxism (involuntary clenching of the teeth). This relaxes the chewing muscles and lessens the strain on the temporomandibular joints (TMJ). Grinding of the teeth is thereby reduced by the amelioration of jaw clenching. This treatment should be repeated every three to four months. Your dentist or oral surgeon can also give you advice on managing this disorder.
