Dental evaluation: Consult with your dentist or orthodontist fro proper diagnosis and recommendations for treatment if indicated.

TMJ dysfunction: The muscles and ligaments that cause your jaw to move are not working smoothly. If you chew gum stop. Eat softer foods next 2-3 weeks. Apply moist heat to the joint area. Stress plays a big role in triggering TMJ problems. Find activities to help reduce your stress level. See your dentist for more detailed help.

TMJ click: Talk to your dentist about your click. Many people have a click in their jaw and this can progress to a painful condition foe some people. It is best to get it checked. In the meantime avoid opening wide and popping the jaw.

Ask your Dentist: Often clicking is the earliest sign of joint dysfunction. Some people have a click and never any other problems. Some people have a click as the first sign of joint derangement. You mention an underbite. It would be prudent to see an Orthodontist as well as your Dentist. Working together they can properly diagnose you and suggest the best plan of treatment.

See OFP expert: Since some types of TMJ problems can lead to more serious conditions, early detection and treatment are important. Orofacial Pain provides diagnosis and management of pain in the face, mouth (gums, teeth, tongue, etc), TMJ, head, as well as, associated headaches and neck pain. They are the experts in this field. Good luck.

Depends: Depends on how much it bothers you. If you have a painless click with no other symptoms, just monitor it. Dont clench/grind, chew gum or have bad oral habits.
