TMJ (temporomandibular joint) and myofascial pain problems can involve the jaw joints, bite, chewing muscles, facial muscles, and surrounding head and neck structures. Patients may notice jaw soreness, muscle tenderness, clenching, grinding, headaches, difficulty chewing, tooth wear, jaw fatigue, or discomfort around the temples, cheeks, ears, or jaw.
In many cases, symptoms are related to a combination of muscle overactivity, bite discrepancies, clenching or grinding habits, joint strain, stress-related muscle tension, and uneven forces on the teeth. A careful evaluation can help determine whether the discomfort appears to be primarily muscle-related, bite-related, joint-related, or a combination of factors.
Dr. Robert DeVoll’s approach to TMJ and myofascial pain focuses on identifying and reducing contributing factors where possible. Treatment may include correcting bite discrepancies, adjusting uneven bite forces when appropriate, using a custom nightguard appliance to help protect the teeth and reduce strain from clenching or grinding, and Botox® treatment of affected muscles of mastication when appropriate.
Botox® may be considered for selected patients when overactive chewing muscles contribute to jaw pain, clenching, muscle tenderness, or excessive bite forces. It is not the right treatment for every patient, and recommendations depend on the diagnosis, symptoms, bite findings, muscle involvement, and overall treatment goals.
The goal of treatment is to reduce harmful forces, protect the teeth and restorations, improve comfort, and help patients better manage muscle-related jaw pain over time. A personal evaluation is needed to determine which treatment options are appropriate.
