Formally known as bruxism, teeth grinding and clenching isn't uncommon.
According to HuffPost, some estimates suggest about 10% of Americans regularly grind their teeth, and 20% regularly clench their teeth together.
Now, dentists say they’re seeing a lot more of both during the COVID-19 pandemic.
A dentist can, by examination, tell you if you're grinding, clenching, or both.
Your dentist can also create a custom mouth guard to wear at night.
