Smile! Dr. Fauci guarantees the Tooth Fairy won't catch COVID-19 on Will Smith's new show

Dwayne "The Rock" Johnson may have played the Tooth Fairy. But Will Smith is now fielding all questions related to the health of the mystical creature amid the coronavirus pandemic.

On his new Snapchat series "Will From Home," Smith virtually hosted Dr. Anthony Fauci on Wednesday to answer "allllll the things your kids are askin’ about coronavirus."

In a clip shared to Smith's Instagram, 7-year-old Los Angeles resident Ava Allen (who is missing a front tooth) asked the director of the National Institute of Allergy and Infectious Diseases: "Can the tooth fairy still come if I lose my tooth, because of the coronavirus? And can she catch the virus?"

Fauci, a member of the Trump Administration's White House Coronavirus Task Force, told little Ava not to "worry about the tooth fairy."

"So when … your tooth (falls) out, you stick it under the pillow and I'll guarantee you that that tooth fairy is not going to get infected and is not going to get sick," he added.

Smith grinned, flashing his own pearly whites.

Cameron Lafemina, a 6-year-old from East Northport, New York, had another question: "What does 'COVID' stand for?"

Fauci responded, "It stands for 'Corona Virus Disease – 2019 … when the first cases were recognized in China."

The first episode of "Will From Home" premiered on Snapchat two weeks ago, with new episodes dropping every Monday, Wednesday and Friday.

His guests have included Tyra Banks, Johnny Knoxville and rapper Joyner Lucas.
