“Waking up with a sore jaw or dull headache without knowing why? You might be grinding your teeth in your sleep. Bruxism is the involuntary clenching or grinding of teeth, most commonly occurring during sleep or moments of intense stress. It's driven by a combination of psychological tension and misfiring muscle activity in the jaw. Over time it can wear down enamel and strain jaw muscles. Building consistent stress management habits and maintaining a relaxing bedtime routine may help reduce its frequency.”

Over time, bruxism can erode enamel and strain the jaw muscles, and adopting stress‑management techniques and a calming bedtime routine can help lessen its frequency.
