What Is TMD and Why Does It Happen?
TMD is an umbrella term for a group of conditions involving pain or dysfunction in the jaw joint and the muscles that control its movement. Think of the jaw like a sliding door that also pivots: it needs both a smooth track and well-calibrated hinges to work properly. When either the structural components or the surrounding muscles are out of balance, the result is pain, stiffness, or a jaw that locks in place.
Common contributing factors include:
- Teeth grinding or clenching (bruxism), often tied to stress
- Jaw injury or trauma, such as a hit to the face
- Arthritis affecting the joint
- Bite misalignment that places uneven pressure on the joint
- Poor posture that shifts tension into the neck and jaw
According to research from the National Institute of Dental and Craniofacial Research, TMD affects 5% to 10% of the U.S. population, making it one of the most common sources of chronic facial pain. Understanding your unique trigger is key to designing treatment that actually works. That’s why our evaluation process is thorough and never rushed.

What Are the Symptoms of TMJ/TMD?
TMD symptoms are surprisingly varied, which is part of why the condition is frequently overlooked or misattributed to other causes. Many patients arrive having already visited other providers without answers. The most commonly reported symptoms include a persistent or intermittent aching in the jaw, face, or around the ear, along with clicking or grating sounds when opening or closing the mouth. Others notice that their jaw occasionally locks or feels stiff.
TMD-related discomfort often spreads beyond the jaw itself. Frequent headaches, particularly around the temples, shoulder and neck tension, and even ringing in the ears (tinnitus) can all be connected to a stressed temporomandibular joint. If any of these symptoms sound familiar, a TMJ evaluation through our general dentistry services in Sunnyvale is an excellent starting point.

How Is TMJ/TMD Diagnosed?
Diagnosing TMD requires more than a quick look inside your mouth. We conduct a careful clinical examination that assesses the range of motion of your jaw, the sounds the joint makes during movement, and any areas of tenderness in the surrounding muscles. We also review your dental and medical history, because factors like nighttime grinding often hold important clues.
Treatment at Smile Craft Dental is always conservative first, reflecting our commitment to evidence-based care and the latest advancements in dentistry. Many patients experience significant relief through non-invasive approaches before any more involved intervention is ever considered.

What Are the Most Common TMJ/TMD Treatment Options?
The right treatment plan depends on the underlying cause and the severity of your symptoms. Commonly recommended options include:
- Custom night guards or occlusal splints to reduce the impact of clenching and grinding during sleep
- Bite adjustments to correct uneven pressure across the teeth
- Physical therapy techniques to relax and rehabilitate the jaw muscles
- Restorative work, such as dental implants or crowns, when tooth damage is contributing to bite imbalance
Our team walks you through every option with patience and clarity, and we never recommend more treatment than your situation actually calls for.

Can TMD Be Related to Other Dental Issues?
TMD does not exist in isolation. Because the jaw joint is at the center of your entire bite system, its health connects directly to the condition of your teeth, gums, and surrounding structures. Untreated bite problems can accelerate tooth wear or lead to cracks, and patients dealing with ongoing jaw tension sometimes find that restorative dental care is a meaningful part of their recovery plan.
Similarly, patients who grind their teeth at night often see the effects on their smile over time, which is when our cosmetic dentistry services can help restore both function and aesthetics. Addressing the root cause first, then restoring what has been affected, is the sequence we follow to create lasting results.
