Why does it hurt to clench my teeth?

Clenching your teeth can cause pain due to increased pressure on the jaw muscles and joints, leading to muscle fatigue and strain. This action can also irritate the temporomandibular joint (TMJ), which connects the jaw to the skull, resulting in discomfort. Additionally, prolonged clenching may lead to tooth wear, sensitivity, or even headaches, as the muscles and nerves in the jaw become overworked. If you experience persistent pain, it may be beneficial to consult a dental or medical professional for evaluation.
