Your teeth needs protection.
Mouth guard can be change when damaged BUT not your teeth.
Most people are not even aware that they are grinding or clenching their teeth
Bruxism is a condition where a patient grinds or clenches his teeth either unconsciously while awake, or during sleep.
Treatment may not be required for mild bruxism. However some patients have symptoms like pain from jaw joints, locked jaws, clicking sounds from jaw joints, headaches and fracturing of teeth.
Custom-made mouth guards or splints can help bruxism, as well as protect your teeth from further damage.
