Short answer
Jaw clicking, tightness and pain near the ear often relate to the temporomandibular joint and the muscles around it, frequently linked to clenching or grinding, stress, or bite factors. Many cases improve with simple self-care; persistent or locking symptoms should be assessed.

The joint and the muscles around it
The temporomandibular joint sits just in front of each ear and does an extraordinary amount of work every day. Clicking on opening, tenderness in the muscles of the cheek and temple, and a tight or tired jaw are common complaints.
A click on its own, with no pain and no restriction, is often not a problem. Pain, locking, or a change in how your teeth meet is worth investigating.
Clenching and grinding
Many people clench during concentration or grind at night without knowing it. Tell-tale signs include waking with a tight jaw or headache from the temples, flattened or chipped tooth edges, sensitivity, and ridging along the side of the tongue or inside the cheek.
What usually helps first
Soft food for a period, avoiding chewing gum and wide yawns, warm compresses, and consciously keeping teeth slightly apart during the day all reduce load on the joint. Gentle jaw exercises can help, and stress management matters more than people expect.
Where grinding is involved, a custom night guard protects the teeth and often reduces morning symptoms.
When to be checked
Persistent pain, a jaw that locks open or closed, difficulty opening wide enough to eat, or a bite that suddenly feels different all deserve assessment. Dental causes such as a cracked tooth or an infection can also cause pain that feels like joint pain.
