THE CROWN OF THE REALM IS MISSING!

QUEEN ELIZABETH has shockingly lost a front tooth — and experts are pointing the finger at the titanic family stress the 93-year-old is under!

A royal source reveals Her Highness has been distracted from tending to her own frail health while dealing with the shameful sex scandal tying disgraced son Prince Andrew to pedophile perv Jeffrey Epstein and the bratty antics of grandkid Prince Harry and his high-maintenance wife, Meghan.

She’s also worried sick about her beloved husband, Prince Philip, 98, who has disappeared from public view.

“He’s been at her side and her confidant for more than 70 years,” says a palace source. “She’s terrified of losing him and being alone.”

Adds the insider: “Few healthy people could deal with these troubles — no wonder her teeth are falling out!”
