If you grind excessively at night time, you could damage your teeth by causing fracture or chipping of your teeth. A mouthguard, worn during sleep, can help reduce the damage that grinding can cause.
Mouthguards are made of a soft material which patients find quite comfortable while they balance the pressure across your jaw and create a physical barrier between your upper and lower teeth to protect them from further damage.
Although mouth guards may help reduce muscle activity in your jaw at night, they’re only able to control the condition, not cure it.
