Some people occasionally grind their teeth and do not need treatment, but others can develop a severe habit that can cause serious damage to their teeth and jaw. Teeth grinding, also known as bruxism, can be so damaging over time some people wear their teeth down to tiny stumps and need to have a full-mouth restoration. Many people only grind their teeth at night, so you may not be aware that you are damaging your teeth; however, it is possible to grind or clench your teeth during the day as well. It’s important to seek treatment immediately if you suspect you may suffer from teeth grinding. If left untreated, bruxism can also affect your jaw and can lead to fractured teeth, tooth sensitivity, loose teeth, hearing loss, changing facial appearance, TMJ disorders, chronic pain, and headaches.
