Why Your Jaw Hurts

Your jawbone is also called a mandible. It connects to your skull at a pair of joints known as the temporomandibular joints, or TMJs. These are located just in front of your ears, and they let you open and close your mouth.Your jaw also holds your teeth and gums, which can be sensitive to heat, cold, or pressure. They also can get infected if you don’t keep them clean.

This is one of the most common reasons for jaw pain. About 1 in 8 people may have a TMJ disorder. It’s more common among women. You might get it if you injure your jaw or after an illness. Arthritis or other conditions can attack the cartilage that helps protect your joint.
