Why does my jaw click or ache?
Quick answer
Is jaw clicking a sign of a jaw-joint disorder?
Jaw clicking can happen with temporomandibular disorders (TMD), but painless clicking without locking is common and often does not need treatment.
Pain, restricted opening or a jaw that locks should be assessed. Avoid assuming the cause is your bite or grinding; several structures and factors can contribute.
What symptoms can TMD cause?
TMD is an umbrella term for problems affecting the jaw joint and nearby muscles. Symptoms may include clicking, aching around the jaw or ear, headaches, difficulty opening fully or episodes of locking. The UCLH patient guide notes that a click is not always painful and many cases improve without complex treatment.
Does every click need treatment?
A sound alone, without pain or locking, may not need intervention. Persistent pain, a sudden reduction in mouth opening, a jaw that locks, or symptoms after an injury deserve clinical assessment. Dental, medical or specialist review depends on the symptoms and examination; a click alone does not show that teeth need reshaping.
What may help during a flare-up?
For a short flare, UCLH advises temporary softer foods, avoiding wide opening and habits that strain the jaw, and trying moist heat or wrapped cold if comfortable. Gradually return to usual eating as symptoms settle. Seek advice if symptoms persist, worsen or interfere with eating or sleep. A dentist can assess your jaw and discuss conservative options, including whether a splint is suitable.
