TMJ (Temporomandibular Joint)
The temporomandibular joint (TMJ) is the hinge-like joint that connects your lower jaw to the temporal bones of your skull. This joint plays a crucial role in everyday functions such as talking, chewing, and yawning. When issues arise with this joint, it is referred to as temporomandibular disorder (TMD). TMD is extremely common, affecting over 10 million Americans, with a higher prevalence among women.
Symptoms of TMD
If you are experiencing TMD, you may notice:
- Painful popping or cracking when opening your mouth wide
- Difficulty opening or closing your jaw (lockjaw)
- Swelling and pain on one or both sides of the face
- Pain while chewing or speaking
- Changes in how your upper and lower teeth fit together
Causes of TMD
TMD can stem from various factors, making diagnosis challenging. To determine the cause, we conduct a thorough evaluation, including an assessment of your symptoms, head and neck musculature, detailed medical history, and possibly X-rays.
Common causes of TMD include:
- Teeth grinding (bruxism)
- Arthritis in the jaw joint
- Chronic jaw clenching due to stress
- Hormonal fluctuations
- Bite imbalances or missing teeth
- Trauma to the head, neck, or jaw
Because TMD is more prevalent in women, ongoing research is exploring potential links between female hormones and the disorder.
Treatment Options for TMD
The first step in treating TMD is conservative, non-invasive care. Bite evaluations and adjustments, known as occlusal equilibration, may be recommended to help balance the bite and relax the jaw muscles. In some cases, a custom splint may be needed to properly position the jaw, alleviate discomfort, or assist in diagnosis. Surgery is only considered in severe cases where conservative treatments are ineffective. If teeth grinding is the primary cause, a bite guard can provide significant relief.
TMJ Treatment Methods
- NSAIDs to reduce pain and inflammation
- Cold therapy with ice packs
- Jaw exercises and stretching to improve mobility
- Head and neck massages to relieve tension
- Avoiding excessive strain from yawning, yelling, or chewing tough foods
