Headaches most mornings. A jaw that clicks, or catches, or aches by the afternoon. Teeth that are visibly shorter than they used to be. Pain that sits in front of the ear and spreads into the temple, the neck, the shoulder.
Most people with that combination have already been somewhere else. Usually more than one somewhere: a doctor who reasonably suspected sinus trouble, a neurologist who reasonably suspected migraine, a pharmacy shelf's worth of painkillers. What often has not happened is anybody examining the joint itself.
First, a small clarification that matters. TMJ is the joint. TMD, temporomandibular disorder, is the problem with it. Everyone says TMJ, including us on this page, but what you are looking for is a diagnosis of TMD.
The temporomandibular joint sits just in front of each ear and is a genuine orthopedic joint, with a disc, a capsule and lubricating fluid, exactly like a knee or a shoulder. That framing is the useful one, because it explains both the symptoms and the treatment. Joints get inflamed. Discs slip out of position and click going back in. Muscles that work too hard get sore and refer pain elsewhere. None of that is mysterious, it is just happening somewhere people do not think of as a joint.
Symptoms that point toward it:
One or two of these on their own may mean nothing. Several together, particularly with the morning headache and the worn teeth, is worth an examination.
Usually not one thing, which is why single-cause explanations should make you suspicious. The common contributors are clenching and grinding, often at night and often entirely unknown to the person doing it; arthritis in the joint; a disc that has shifted out of position; an old injury to the jaw or the head; and periods of sustained stress, which drive the clenching that drives everything else.
Worn teeth are frequently the first hard evidence, because enamel does not wear evenly by accident. A partner's complaint about grinding noise at night is the second. Our Learning Center covers the signs of grinding you can spot yourself, and how TMJ affects people day to day.

The examination is hands on and takes time. Nobody diagnoses this from a single x-ray.
We measure how far and how evenly the jaw opens, feel the joints and the muscles through a full range of movement, map where the pain actually refers to, and look at the wear pattern on your teeth. Our Orthophos SL 3D imaging shows the bony structures where that is relevant. See our knowledge and technology in full.
The order is the important part, and it is where this page differs most from others you will read.
Conservative and reversible comes first. Soft diet for a period, heat and cold, gentle jaw exercises, deliberately breaking daytime clenching habits, and addressing sleep and stress where those are driving it. A surprising number of people improve substantially on this alone. It costs almost nothing and forecloses no options.
Then splint therapy. A custom occlusal splint, worn at night, stops the teeth destroying each other and lets overworked muscles settle. This is the single most useful intervention for most patients, and it is still completely reversible. The appliance itself, and how a custom one differs from the drugstore version, is covered on our occlusal night guards page.
Alongside that, adjuncts where they help. Anti-inflammatories, muscle relaxants prescribed by your physician, and physical therapy for the jaw and neck. We are comfortable co-managing with your doctor rather than pretending dentistry owns every part of this.
Restorative work last, and only when it is indicated. Where years of grinding have genuinely destroyed tooth structure, rebuilding the bite with crowns or a full mouth reconstruction can be the right answer. Dr. Fritz Zietsman is a board eligible prosthodontist, which is the specialty for exactly that kind of reconstruction, so when a case genuinely needs it the expertise is in the building. You can read about the whole team and what each of them focuses on.
Nothing that permanently changes your bite until the reversible options have had a fair run.
Grinding down healthy teeth to chase a jaw symptom is not something you can undo if it turns out not to have been the problem. If a practice proposes that as a first step, get another opinion.
Get the joint examined by someone who examines joints.
If you are living with morning headaches and a jaw that clicks, a proper TMD examination is a sensible next step. It is conservative, it is reversible, and it starts with a conversation.
