Most everyone grinds their teeth at night – it’s the degree that varies. So the real question becomes whether your grinding is damaging your teeth, joints or muscles. The mouth is a complicated machine with many different parts, not all of which fit together perfectly. During sleep, we unconsciously grind or clench to force these parts to fit. Stress can further exacerbate the problem, which can result in pain, headaches, and cracked or broken teeth. The good news is that our dentists are specially trained in bite and joint therapy, which can halt or reverse these effects.
