Because bruxism mainly occurs when someone is sleeping, people may not realize it. However, headache or chin pain, especially in the morning, indicates that the person concerned is grinding teeth. Many people do not even know that they have bruxism until their spouse hears their teeth at night.
If you think you may be grinding your teeth, it is advisable to consult a dentist. He or she will check if your teeth are worn or if your chin is cracked. These are signs of bruxism.
