What is TMJ/TMD?
TMJ refers to the temporomandibular joints — the two hinge-like joints that connect your jawbone to your skull, located just in front of each ear. These joints, along with the surrounding muscles, ligaments, and nerves, allow you to open and close your mouth, chew, speak, and move your jaw from side to side. When something disrupts the balance of this system, the result is a condition known as temporomandibular dysfunction, or TMD — often used interchangeably with the term “TMJ disorder.” Bruxism, the chronic clenching or grinding of teeth (frequently during sleep), is one of the most common contributors to and symptoms of TMD. Together, these conditions affect an estimated 10 million Americans, and left untreated, they can cause lasting damage to the teeth, jaw joints, and surrounding muscles.
Causes of TMJ, TMD & Bruxism
TMD can develop for a number of reasons, and often it’s a combination of factors rather than a single cause. Stress is one of the most common triggers, as it frequently leads to jaw clenching and teeth grinding, particularly during sleep. Misaligned teeth or an uneven bite can force the jaw joints and muscles to work harder than they should, gradually straining the system. Injury to the jaw, arthritis affecting the joint, and habits like nail-biting or excessive gum chewing can also contribute. In many cases, the joint itself becomes inflamed or the disc that cushions it shifts out of position, which disrupts smooth movement and leads to the discomfort associated with TMD.
Signs and Symptoms of TMJ, TMD & Bruxism
TMD symptoms can vary widely from person to person, which is part of what makes the condition tricky to self-diagnose. Common warning signs include jaw pain or tenderness, especially near the ears, along with a clicking, popping, or grating sound when opening or closing the mouth. Many patients report frequent headaches or migraines, neck and shoulder pain, and even ringing in the ears (tinnitus). Difficulty or discomfort while chewing, a jaw that feels like it’s locking or getting stuck, and noticeable swelling on the side of the face are also common. Bruxism sufferers often wake up with a sore jaw or a dull headache and may notice their teeth appear worn, flattened, or chipped over time — even if they aren’t aware they’re grinding at night. If any of these symptoms sound familiar, it’s worth having Dr. Feintuch take a closer look before the problem progresses.

What is Involved in TMJ/TMD & Bruxism Treatment?
Diagnosing TMD starts with a thorough evaluation of your bite, jaw movement, and overall oral health. Dr. Feintuch will examine your jaw joints, listen for clicking or popping, check for tenderness, and review your dental and medical history to identify what’s driving your symptoms. In some cases, imaging may be used to get a clearer picture of the joint itself.
From there, treatment is tailored to your specific situation, since TMD rarely responds to a one-size-fits-all approach. Many patients find relief through simple lifestyle changes, such as stress-reduction techniques, dietary adjustments to avoid overworking the jaw, and gentle exercises designed to strengthen and stretch the jaw muscles. Over-the-counter anti-inflammatory medication can help manage pain and swelling during flare-ups.
For patients dealing with bruxism or a misaligned bite, Dr. Feintuch often recommends a custom-fitted mouth guard, worn at night, to keep the jaw in a more balanced position and prevent further wear on the teeth. Unlike generic, store-bought guards, a custom device is molded specifically to your bite for a more comfortable fit and more effective, lasting results. In more complex cases, additional treatment may be recommended to correct an underlying bite issue contributing to the problem.
TMD is a progressive condition, meaning it tends to get worse without treatment. The sooner it’s addressed, the easier it typically is to manage — and the less wear and tear your teeth and jaw joints will sustain in the meantime.
Frequently Asked Questions
Is TMJ disorder the same as bruxism?
Not exactly, though the two are closely related. TMJ/TMD refers to dysfunction of the jaw joint itself, while bruxism refers to the habit of clenching or grinding teeth. Bruxism is one of the most common causes of TMD, and many patients experience both at the same time.
Can TMD go away on its own?
Mild cases triggered by temporary stress or a minor injury sometimes improve with rest and self-care. However, TMD is generally a progressive condition, and ongoing symptoms are a sign that professional evaluation and treatment are needed to prevent further wear on the teeth and joints.
Will I need a mouth guard forever?
Not necessarily. Many patients wear a custom night guard for an extended period to relieve symptoms and protect their teeth, but the length of treatment depends on the underlying cause. Dr. Feintuch will reassess your progress at follow-up visits and adjust your treatment plan as needed.
Is TMJ treatment covered by dental insurance?
Coverage varies by plan and by the specific treatment recommended. Our team can help you understand your benefits and discuss options during your visit.
How do I know if my headaches are related to TMJ?
TMJ-related headaches often center around the temples or behind the eyes and are frequently accompanied by jaw tenderness, clicking, or a history of teeth grinding. If your headaches occur alongside any of these symptoms, it’s worth scheduling an evaluation with Dr. Feintuch.
