What is TMD and How Mint Dental Care Can Help

November 5, 2025

Do you frequently wake up with a headache or find that your jaw makes a painful clicking sound when you chew? These symptoms might point to a common condition: Temporomandibular Joint Disorder (TMJD), often called TMD. 

At Mint Dental Care, your trusted general dentist in Sunnyvale, CA, we specialize in diagnosing and treating jaw pain to restore your comfort and quality of life. 

1. What is TMD? (The Breakdown) 

The TMJ (Temporomandibular Joint) is the "hinge" that connects your lower jawbone (mandible) to your skull. You have two of them, one on each side in front of your ears. They allow you to move your jaw up and down, side to side, and forward, which allows you to talk, chew, and yawn. 

TMD (Temporomandibular Disorder) is a term for problems involving these joints and their associated facial muscles and ligaments. When your TMJ, muscles, and ligaments are out of alignment or under stress, you may experience dysfunction and pain. 

2. Recognizing the TMD Symptoms 

TMD symptoms can range from mildly annoying to more severe, causing pain or an inability to open your mouth or to eat. If you notice any of these issues, it's time to visit Mint Dental Care

Jaw Pain and Tenderness: A constant ache or tenderness around the jaw, face, or ears. 

Clicking or Popping: A noticeable sound when opening or closing your mouth.

Chronic Headaches: Especially tension headaches or migraines that start when you wake up. 

Difficulty Chewing: Pain or a limited ability to open your mouth wide.

Lockjaw: The jaw temporarily getting stuck in an open or closed position.

Ear-Related Issues: A ringing in the ears (tinnitus) or a feeling of fullness. 

3. Causes and Your Sunnyvale General Dentist's Role 

The causes of TMD are varied, but your general dentist is key to finding the root issue: 

  • Malocclusion (Bad Bite): If your teeth don't fit together properly, your jaw shifts to compensate, straining the joint over time. 
  • Injury or Arthritis: Trauma to the jaw or degenerative joint disease.
  • Stress: High stress often leads to jaw clenching and muscle tension. 
  • Teeth Grinding or Clenching (Bruxism): This is the most common cause. Unconscious grinding, especially during sleep, puts enormous pressure on the TMJs.

At Mint Dental Care in Sunnyvale, we use a comprehensive dental exam to assess your bite, jaw alignment, and muscle health to determine whether your symptoms are caused by TMD. 

4. Effective TMD Treatment in Sunnyvale, CA 

The good news is that most cases of TMD respond very well to conservative, non-surgical treatment options here in our office: 

Custom Night Guards: This is the most effective therapy. We create a custom-fitted oral appliance that you wear while sleeping. It prevents your teeth from clenching and grinding, allowing the jaw muscles and TMJ to relax and heal. 

Self-Care Guidance: We provide personalized advice on relaxation techniques, jaw exercises, and dietary changes (like avoiding hard or chewy foods) to manage symptoms at home. 

Bite Adjustments: Minor reshaping of the biting surfaces of your teeth can help guide your jaw into a more balanced, comfortable resting position.
