This phenomenon has become more common and can lead to the premature break down of the tooth enamel and tooth decay. The best solution is for a bite guard to be made which works normally when sleeping.
If a bite guard is used in the early stages of detection of a grinding/clenching problem much can be done to save the teeth before more expensive crown solutions are required.
Bruxism is the medical term for grinding the teeth and clenching the jaw. It can occur sometimes without any pain or discomfort. However, regular grinding can cause jaw pain and grind down your teeth. It can also cause head and ear ache.
About 80% of cases occur subconsciously during sleep and is usually associated with stress and anxiety. People find it comes and goes but is normally associated with stressful periods.
There are a number of possible treatments involving behavioural therapies and mouth guards or mouth splints. Please raise any issues that you may have with grinding with your dentist. We can have mouth guards made for you and suggest other therapies to help.
