All Demi Moore wants for Christmas is her two front teeth — we would hope.

The actress appeared on The Tonight Show and told Jimmy Fallon about how she lost her two front teeth. Turns out, she was so damn stressed!

“I sheared off my front teeth. I’d love to say it was skateboarding or something really kind of cool, but I think it’s something that’s important to share, because I think it’s literally, probably after heart disease, one of the biggest killers in America, which is stress,” she shared. “Stress sheared off my front teeth. But, in an effort to get ready for you, I wanted to make sure my teeth were in.”

Later she revealed to Page Six: “They happened a year apart but the fact remains that I sheared off both my front teeth. Thank God for modern dentistry. Without it, I wouldn’t be smiling on the red carpet.”

Page Six also spoke with Dr. Gary Glassman, a dentist, who said there were likely other factors:

“I would suspect that there were definitely other factors involved,” he said, noting that stress can cause bruxism, otherwise known as teeth grinding. “That can wreak havoc and when you’re under stress and have a lot of anxiety. That’s the No. 1 reason why people grind their teeth.”
