Bruxism is the unintentional clenching and grinding of teeth, and can lead to dental issues and discomfort including jaw clicking, tension, headaches and cracking of teeth. It often occurs during sleep or subconsciously during the day. It can also contribute to TMJ (temporomandibular joint) dysfunction. Effective treatments include reducing symptoms, preventing dental damage and addressing underlying causes. Customised splints are recommended to protect teeth and stress management techniques. Botulinum toxin injections into the masseter muscle is effective in reducing the size of the muscle, relaxing it and reducing the intensity of grinding and clenching.

The temporomandibular Joint (TMJ) dysfunction (also referred to as TMJ disorder or TMD) is a condition affecting the temporomandibular joint (jaw joint) and the surrounding muscles that control movement of the jaw.

The TMJ is hinge like joint that connects the jawbone (mandible) to the skull and assists in chewing, speaking, breathing and swallowing. Because it is a highly flexible joint, it is susceptible to disorders such as TMD (temporomandibular joint disorder) or bruxism (teeth grinding).

How Is TMD And Bruxism (Teeth Grinding) Treated?

Temporomandibular Joint Dysfunction and Bruxism are treated with a combination of treatments involving a team of specialists. It is highly recommended that a thorough dental examination is performed by a dentist to identify dental issues and contributing factors such as masseter hypertrophy.

At Kaya Cosmedica, we offer muscle relaxing injections using the same substance as anti-wrinkle injections for TMD and bruxism relief and jawline enhancement. While most people know these injections for their cosmetic benefits, they are also used therapeutically to treat a variety of muscle-related conditions.

By administering muscle relaxants into the temporalis and masseter muscles on the sides of the face, we can temporarily limit muscle contraction. This approach helps reduce the tension, inflammation, and pain associated with TMD and Bruxism. Anti-wrinkle injections do not treat the root cause of TMJ disorders, but controlling the unpleasant symptoms can make pursuing other treatment options easier and more comfortable.

In addition Dr PK recommends a holistic approach to treatment including stress management, dental splints/treatment, physical therapy, medications such as anti-inflammatories and addressing any underlying causes such as sleep disorders. Early diagnosis and treatment can help prevent further damage to teeth and the TMJ.
