Temporomandibular joint and muscle disorders (TMJ disorders) are conditions that can cause significant discomfort and affect your ability to chew, speak, and even sleep. As dental hygienists, we aim to educate and help prevent these disorders so you can maintain a healthy and pain-free life. 

What Are TMJ Disorders?

TMJ disorders involve problems with the temporomandibular joints and the muscles that control jaw movement. You have two temporomandibular joints in your body, one on each side of your head, located just in front of your ears. These joints connect your jawbone to your skull and allow your jaw to move smoothly up and down and side to side, enabling you to talk, chew, and yawn.

When there is an issue with these joints or the surrounding muscles, it can lead to TMJ disorders. These issues can arise from a variety of causes, including:

• Injury to the jaw or head

• Arthritis

• Jaw misalignment

• Teeth grinding or clenching (bruxism)

• Stress, which can cause tension in the jaw muscles

TMJ disorders are fairly common and can manifest in various ways. It's important to recognize the symptoms so you can seek treatment promptly. Symptoms may include:

• Pain or tenderness in the jaw

• Pain in one or both temporomandibular joints

• Aching pain in and around your ear

• Difficulty chewing or pain while chewing

• Aching facial pain

• Locking of the joint, making it difficult to open or close your mouth

• Clicking or popping sounds when opening your mouth or chewing (sometimes without pain)

PREVENTION IS KEY

Preventing TMJ disorders is key to maintaining a healthy jaw. Here are some steps you can take:

1. Practice Good Posture: Keep your head aligned with your spine and avoid slouching, especially when working at a desk.

2. Avoid Overuse: Refrain from excessive chewing (like chewing gum) and avoid hard or chewy foods.

3. Manage Stress: Stress can lead to jaw clenching and teeth grinding. Techniques like yoga, meditation, and regular exercise can help reduce stress.

4. Wear a Mouthguard: If you grind your teeth at night, a custom mouthguard can protect your teeth and reduce strain on your jaw.

5. Jaw Exercises: Gentle jaw exercises and stretches can help improve jaw function and reduce tension.
