Jaw Pain
A sore jaw can mess with your eating, sleeping, and just about everything else. Figuring out the cause is the first step to feeling better.
In one sentence: Jaw pain is commonly caused by teeth grinding (bruxism), TMJ disorder, or muscle tension from stress, and it can usually be managed with self-care and a night guard.
Quick Answer
Most of the time, jaw pain comes from either TMJ problems, grinding your teeth (especially at night), or a dental issue like an infection. TMJ can cause pain, clicking sounds, and make it hard to move your jaw. You can try some things at home to help, like eating soft foods, using a warm compress, and trying to relax your jaw. But if the pain is really bad or isn't going away, it's time to see a professional.
What You Need to Know
Your jawbone connects to your skull with the temporomandibular joint (TMJ). You have one on each side of your face, and they're pretty complex. They let you do all sorts of things, like talk, chew, and yawn. When something’s off with this joint or the muscles around it, doctors call it a TMJ disorder (or TMD).
TMD is the number one reason for jaw pain. You might feel tenderness in your jaw, an ache near your ear, or have a tough time chewing. Sometimes you'll hear a clicking or popping sound when you open your mouth, or your jaw might even lock up. What causes it? All sorts of things. Stress, grinding your teeth, arthritis, or even an old jaw injury can be the culprit.
Grinding your teeth is another big one. A lot of people do it in their sleep and have no idea. Waking up with a sore jaw or a headache is a classic sign. You might also notice your teeth look worn down, or you might have even chipped a tooth. A night guard from your dentist can be a real lifesaver here. It protects your teeth and helps your jaw muscles relax.
But that's not all. Jaw pain can also come from a tooth infection (like an abscess), problems with your wisdom teeth, or even a sinus infection. And in some rare cases, jaw pain can be a sign of a heart attack, especially for women. So it's good to get it checked out.
Possible Causes
TMJ Disorder (TMD)
medium urgencyThe jaw joint itself is acting up, causing pain, clicking, and stiffness.
Teeth Grinding (Bruxism)
medium urgencyClenching or grinding your teeth (especially at night) puts a lot of strain on your jaw.
Dental Infection/Abscess
high urgencyA nasty infection in a tooth root can send pain shooting up into your jaw.
Wisdom Teeth
medium urgencyWhen wisdom teeth don't have room to grow in, they can make the back of your jaw hurt.
Stress and Tension
low urgencyFeeling stressed? You might be clenching your jaw without realizing it.
Arthritis
medium urgencyJust like in other joints, arthritis can affect your TMJ and make it painful and stiff.
What You Can Do at Home
Stick to soft foods for a bit. No hard, chewy, or crunchy stuff.
Put a warm compress on your jaw for 15-20 minutes a few times a day.
Try to relax your jaw. Keep your lips together but your teeth apart.
Don't yawn too wide, and try not to chew gum.
Ibuprofen can help with the inflammation and pain.
Find ways to de-stress. The less you clench, the better your jaw will feel.
