Why does my jaw click?

The click is your temporomandibular joint - the hinge just in front of your ear - with a disc that slips slightly out of step as the jaw opens, then snaps back. NIDCR notes jaw sounds are common, and painless clicking without other symptoms often needs no treatment at all - many people click for years without it progressing. What aggravates it: chewing gum and tough or chewy foods, wide yawning, clenching and grinding - often stress-driven or during sleep - and poor posture, which loads the jaw muscles. Self-care comes first even when it does bother you: softer foods, smaller bites, no gum, heat on the muscles, and awareness of daytime clenching - teeth apart, lips together is the resting rule. Over-the-counter anti-inflammatories help flare-ups. If you grind at night, a dentist-made guard protects both teeth and joint. The flags for professional evaluation: clicking with pain, a jaw that locks open or closed, trouble opening wide enough to eat, or a bite that suddenly feels different. Those suggest the joint needs real treatment - dentists and orofacial specialists handle it, and NIDDK... NIDCR emphasizes conservative, reversible treatment first. A click alone, pain-free for years, usually just needs monitoring. Pymander is a free AI doctor, 24/7 by text. Describe the click and any pain, and it can help you decide whether to see someone.
