Bruxism is when a person involuntarily grinds their teeth while they sleep. Many people may suffer from bruxism and not know what the problem is. Symptoms of bruxism include any kind of alteration of your teeth, tooth pain and tired jaw muscles. Generally, people are not able to stop this problem without treatment. In many cases a night guard can be used and/or a jaw relaxant can be prescribed. If you suspect you may be suffering from bruxism, it’s essential to make an appointment with a dentist as soon as possible.
