Actress Demi Moore revealed on "The Tonight Show Starring Jimmy Fallon" she lost two front teeth due to stress (video below).
"I sheared off my front teeth," Moore admitted, the Daily Mail reports. "I'd love to say it was skateboarding or something really kind of cool, but I think 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 in America, which is stress."
"Stress sheared off my front tooth," she said. "But, in an effort to get ready for you, I wanted to make sure my teeth were in."

"They love seeing me without my teeth, because they think it makes me look more vulnerable and human," she explained.
For many, it was a shock to learn people could lose their teeth due to stress, never mind that Moore had a toothless smile recently.
"Is that a thing?" writes one Daily Mail reader. "I don't think that's a thing, if a Hollywood pampered princess is losing teeth, we'd all be walking around toothless."
But according to experts, Moore is onto something. A study reveals stress may cause periodontal diseases which, if left untreated, can cause tooth loss.
"More research is needed to determine the definitive relationship between stress and periodontal diseases," said study author Daiane Peruzzo, PhD, reports ScienceDaily. "However, patients who minimize stress may be at less risk for periodontal diseases."
Stress can also lead to a number of poor habits, such as teeth grinding and poor cleaning, which can lead to problems for the mouth, teeth and gums, such as canker sores, reports WebMD.
"Individuals with high stress levels tend to increase their bad habits, which can be harmful to periodontal health," explained Preston D. Miller Jr., DDS. "They are less attentive to their oral hygiene and may increase their use of nicotine, alcohol or drugs. Patients should seek healthy ways to relieve stress through exercise, balanced eating, plenty of sleep and maintaining a positive mental attitude."
