Demi Moore has revealed the less than picture-perfect reality behind her dazzling Hollywood smile.

The actress shocked her million-plus Twitter followers by posting photos of her minus a front tooth, taken during a dentist visit.

Ashton Kutcher's missus can be seen wearing sunglasses and a big gap-toothed grin in four pictures.

She writes: "I lost it and had to have it fixed! I personally thought this look went out after you were eight, didn't know I would be rocking it again!

"Happy to share and always appreciate the opportunity to find humility!!! Or at least be able to laugh at myself!"
