When you clench and grind your teeth, even if you don’t realize that you’re doing it, you cause damage to the biting surfaces of your teeth and dental restorations.
This can cause teeth to wear down over time. If this wear is not prevented by using a mouthguard at night, the damage can build up until all the teeth need to be restored by placing dental crowns.
Through severe teeth wear, it is also possible that your ideal jaw position will be affected. This can result in jaw pain and headaches, as well as muscle tension that can start to spread to your neck, back and shoulders.
