Could Covid-19 Cause Your Teeth to Fall Out?

Earlier this month, Farah Khemili popped a wintergreen breath mint in her mouth and noticed a strange sensation: a bottom tooth wiggling against her tongue. Ms. Khemili, 43, of Voorheesville, N.Y., had never lost an adult tooth. She touched the tooth to confirm it was loose, initially thinking the problem might be the mint. The next day, the tooth flew out of her mouth and into her hand. There was neither blood nor pain. Ms. Khemili survived a bout with Covid-19 this spring, and has joined an online support group as she has endured a slew of symptoms experienced by many other “long haulers”: brain fog, muscle aches and nerve pain.
