Jaw pain is common. Living with it doesn't have to be.

What is TMJ, and what is TMD?

TMJ stands for temporomandibular joint, the hinge just in front of each ear where your lower jaw meets your skull. Everyone has two. When people say they "have TMJ," they usually mean TMD, a temporomandibular disorder: any problem with those joints or the chewing muscles around them.

It's one of the busiest joints you have. It opens, closes, slides forward and shifts side to side every time you talk, chew, yawn or swallow. So when it gets irritated, you notice all day long.

TMJ symptoms: what a jaw problem feels like

TMD shows up differently for different people. The most common signs:

• Pain or tenderness in the jaw, the face or just in front of the ear
• Clicking, popping or grating when you open or chew
• A jaw that catches, or gets stuck open or closed
• Headaches, often at the temples and often on waking
• Earaches or a full feeling in the ear with no ear infection
• Neck pain, or ringing in the ears
• Tired, sore chewing muscles, or teeth that ache in the morning
• Trouble chewing, yawning wide or even talking comfortably
• Teeth that look flat, chipped or worn down from grinding

What causes jaw pain?

Usually it's more than one thing. Clenching or grinding, often at night and often without knowing it, overworks the muscles and loads the joint. Stress tends to make clenching worse. A bite that doesn't meet evenly can strain the whole system. So can an old injury, arthritis in the joint, or habits like chewing gum all day or biting your nails.

Because the causes overlap, a good exam matters more than a quick guess. Treating only the teeth when the problem is muscle, or only the muscle when the bite is the real issue, tends to disappoint.

How we diagnose TMD

We start by listening: where it hurts, when, and what makes it better or worse. Then we check how far and how straight your jaw opens, feel and listen for clicking as you move, and press gently on the joint and chewing muscles to find the sore spots. We look for wear on your teeth, check how your bite comes together, and take x-rays as needed.

If something points beyond the jaw, like joint damage that needs a specialist or symptoms that sound more like an ear or nerve issue, we'll tell you and help you find the right doctor.

Night guards and occlusal splints

For most people, the first real treatment is a custom occlusal splint: a thin, hard appliance made from a digital scan of your teeth that fits over one arch. It takes stress off the joint and keeps your top and bottom teeth from grinding against each other, a common cause of TMJ symptoms. The jaw settles into a more relaxed position, which gives the joint and muscles a chance to rest and heal. Depending on your case, you may wear it just at night or during the day too.

A night guard is the simpler cousin. Its main job is protecting your teeth from grinding. Depending on what we find, you may need one or the other, and we'll explain which and why.

Store-bought boil-and-bite guards can help in a pinch, but they're soft and bulky and don't control how your jaw rests. Some people even clench harder on a soft guard. A custom splint is made for your bite and adjusted in the office until it's comfortable.

How long does TMJ treatment take to work?

Relief is gradual. Many people notice a real difference within about six to eight weeks of wearing a splint as directed, and the full benefit often takes three to six months while the muscles and joint adjust. Wearing it every night matters more than anything else.

We'll see you back to check the fit and fine-tune it, and if you're not improving the way we expect, we change course instead of waiting it out.

Things you can do at home for jaw pain

These won't fix the cause on their own, but they help, and they help your splint work:

• Eat softer foods and cut things into small bites for a while
• Skip gum, chewing ice and very chewy foods
• Use warm compresses on tight muscles and cold for sharp flare-ups
• Catch daytime clenching: lips together, teeth apart, jaw loose
• Make room for relaxation techniques, since stress tends to tighten the jaw
• Try the gentle jaw stretches we show you, never forcing it
• Take over-the-counter anti-inflammatories if they're safe for you

Can TMJ disorder cause headaches or migraines?

There's a real link. Research has found jaw disorder symptoms are much more common in people who get frequent migraines, and constant pain signals from the jaw may make headaches easier to set off. That doesn't mean your jaw causes your migraines, but for some people it's one of the triggers, and calming the jaw can mean fewer or milder headaches.

Jaw pain can change how you talk, too. When moving your jaw hurts, it's natural to open less, and speech can start to sound tight or a little slurred. That usually improves as the pain does.

When a splint isn't the whole answer

If your bite is part of the problem, straightening your teeth can help. Invisalign or braces can bring your teeth together more evenly so the joint isn't fighting them. We only suggest that when the bite is really a factor. Teeth worn or broken by years of grinding can be rebuilt once the grinding is under control.

Surgery is rare and only considered after conservative care has had a fair chance. If it ever comes to that, we'll refer you to a specialist.
