How Your Tmj Could Get Dislocated and What to Do if it Does?
Posted on 7/15/2025 by Treasure Valley Oral & Facial Surgery |
 The temporomandibular joint, or TMJ, is a hinge connecting your jawbone to your skull. It's responsible for jaw movement, allowing you to talk, eat, and yawn. While a strong joint, your TMJ can dislocate, causing pain and discomfort. Let's explore the causes of TMJ dislocation and what to do if it happens to you.
What Causes TMJ Dislocation?
Several factors can contribute to TMJ dislocation, including:
| • |
Wide Mouth Opening: Opening your mouth too wide, such as during a big yawn or dental procedure, can stretch the ligaments supporting the TMJ, potentially causing dislocation. |
| • |
Direct Impact: A blow to the jaw, like during a sports injury or car accident, can dislocate the joint. |
| • |
Underlying Conditions: Certain medical conditions like arthritis or Ehlers-Danlos syndrome can weaken the ligaments, increasing the risk of dislocation. |
| • |
Teeth Grinding: Chronic teeth grinding (bruxism) can put excessive stress on the TMJ, leading to dislocation. |
| • |
Jaw Misalignment: Misalignment of the teeth or jaw due to factors like missing teeth or malocclusion can strain the TMJ, making it more prone to dislocation. |
What Happens When Your TMJ Dislocates?
A dislocated TMJ can be quite painful. You might feel:
| • |
Pain in the jaw joint, radiating to the ear or face |
| • |
Difficulty or inability to close your mouth |
| • |
Locking of the jaw |
| • |
Clicking or popping sounds in the jaw |
| • |
Swelling around the jaw joint |
What to Do if Your TMJ Dislocates?
If you suspect your TMJ is dislocated, don't try to manipulate it yourself. Here's what you should do:
| 1~ |
Apply Ice: Apply an ice pack to the affected area to reduce swelling and pain. |
| 2~ |
Seek Medical Attention: See a doctor or oral surgeon as soon as possible. They will gently manipulate the joint back into place. |
| 3~ |
Follow Instructions: After the TMJ is relocated, your doctor will provide instructions for managing pain and preventing future dislocations. This may include medications, soft diet recommendations, and jaw exercises. |
Preventing TMJ Dislocation
While not all TMJ dislocations are preventable, you can take steps to minimize the risk:
| • |
Avoid Wide Mouth Opening: Be mindful of how wide you open your mouth, especially during activities like yawning or dental procedures. |
| • |
Wear a Mouth Guard: If you grind your teeth, use a custom-fitted mouth guard to protect your TMJ and teeth. |
| • |
Address Misalignment: Consult your dentist or orthodontist if you have misaligned teeth or jaw to discuss corrective options. |
| • |
Maintain Good Oral Care: Regular dental checkups and good oral hygiene practices can help maintain a healthy TMJ and prevent complications. |
Conclusion
TMJ dislocation can be a painful experience, but with prompt treatment and proper management, you can recover and prevent future occurrences. By understanding the causes and symptoms, and taking steps to protect your TMJ, you can maintain optimal oral health and function.
