Teeth grinding is harmful for several reasons. First, it causes damage to the teeth by wearing the enamel off the biting surface of the tooth and along the gumline. This can lead to tooth sensitivity. Second, the forces generated from grinding can cause cracks to form in the teeth and can cause the teeth to break.
Not only can severe grinding damage teeth and result in tooth loss, it can also affect your jaws, result in hearing loss, cause or worsen TMD/ TMJ, and even change the appearance of your face. Â© 2005-2015 WebMD, LLC. All rights reserved. Source article on WebMD.
