In the US, where perfect Hollywood smiles have always been big business, wannabe models are now resorting to having gaps inserted into their teeth.
Dr Marc Lowenberg, a cosmetic dentist in Manhattan, told the New York Times: "The white standard got too white. The perfection standard got too perfect."
Vincent Devaud, a ceramist from Pasadena in California, added: "What makes a person desirable and attractive? It's not the symmetry ; it's perfect imperfections."
