Tooth grinding and jaw clenching (also called bruxism) is often related to stress and anxiety. It doesn't always cause symptoms but many people experience facial pain and headaches. It can wear down your teeth and cause repeated broken fillings. It occurs whilst we sleep but also during the day, especially if we are concentrating or under stress.

It can also be a symptom of sleep apnoea so it is important to rule this out before we provide treatment.
