A lot of people grind or clench their teeth at night without realising it. Because it happens in deep sleep, they only see the side effects during the day. One common clue is waking up with a tight or tired jaw, as if it has been working hard all night. Some people notice dull headaches around the temples when they get out of bed.
Your teeth may also start telling the story. Flattened chewing surfaces, small chips, sensitivity to cold, or hairline cracks can appear over time. A partner may mention grinding noises at night. Even if you sleep alone, your dentist can often spot signs of wear during a routine check-up.
Night-time grinding is often linked with stress, anxiety, or an overactive mind. It can also be related to bite issues or sleep disturbances in some people. Ignoring it isn’t wise; long-term grinding can damage enamel, stress fillings and put pressure on jaw joints.
Simple steps include working on stress management, relaxing the jaw consciously during the day, and avoiding very hard or chewy foods if your muscles are already sore. In many cases, a dentist-made night guard can protect your teeth while you work on underlying causes.
