Many people clench their jaws when deeply focused on a screen. You might not notice it until your jaw feels tired or your head aches at the end of the day. This “focused jaw” habit quietly puts pressure on teeth, jaw joints and muscles for hours.
Watch yourself while you work. Are your teeth touching most of the time? Ideally, when you’re at rest, your upper and lower teeth should be slightly apart, with lips closed and jaw relaxed. Constant contact turns normal teeth into mini grinding tools, which can wear enamel and stress fillings.
Simple reminders help. Stick a small note on your monitor that says “Relax jaw” or set phone reminders every hour. When you notice clenching, drop your shoulders, take a slow breath and gently separate your teeth. Adjust your posture too – leaning forward with neck strain often goes together with jaw tension.
If you wake up with sore jaw muscles, headaches or sensitive teeth, night-time clenching may also be happening. A dentist can check for signs of wear and, if needed, suggest a night guard to protect teeth while you work on stress and posture during the day.
