TMJ / Masseter Tox

The masseter is one of the powerful muscles used for chewing, and for some people it can become overactive with jaw clenching or grinding. Carefully placed botulinum toxin (neurotoxin) injections into the masseter temporarily reduce excessive muscle activity. For appropriately selected patients, this may help lessen jaw tension and the force of clenching while preserving normal everyday jaw function.

Because jaw pain, clenching and temporomandibular disorders can have several different causes, treatment should be individualized. Masseter tox is not a cure for every TMJ problem and is often considered as one part of a broader plan. A dental evaluation is also important when grinding or clenching is present. Your dentist can evaluate your teeth and bite and determine whether a protective night guard or other conservative care may be appropriate to help protect the teeth.
