Occasional bruxism usually does not result in damage to the teeth or jaw. However, chronic teeth grinding can cause serious dental issues. In some cases, grinding can result in tooth fracture, loosening of teeth, or the loss of a tooth or teeth. Grinding over years without treatment can wear the teeth down to stumps, which will require bridges, crowns, root canals, implants, or possibly even dentures to repair.
Not only is bruxism bad for your teeth, it is also damaging to the jaw. Grinding can result in hearing loss, change the appearance of your face, and TMJ.
