A slightly overlapped canine or discoloured mark near the gum line are becoming popular requests during cosmetic dentistry procedures.
Patients scheduling an appointment for veneers – wafer-thin shells that are bonded to the front of the original tooth – are increasingly asking for natural-looking flaws to help maintain a subtle look, according to the New York Times.
Dr Thomas Connelly, a cosmetic dentistry expert practicing in Manhattan, said: "[People] just want to have a nice smile. They don't want to be known for their smile."
What's more, patients that have opted for a brilliant while, perfectly straight set of veneers have been known to return to have flaws or imperfections added to their mouth.
A spokesman for the UCLA Center for Esthetic Dentisry added that texture in the enamel is one way to replicate human teeth.
This type of cosmetic dentistry can be used to straighten a crooked bite, fill spaces or gaps, or repair a tooth that has been damaged or chipped.
