Is there such a thing as being too perfect? Apparently so, at least in dentistry where perfectly symmetrical and overly white teeth actually make you less beautiful:
Dr. Jeff Golub-Evans, a dentist on the Upper East Side, encourages
patients to allow him to slightly rotate a tooth, or to vary the length of teeth. “What I’ve found is that if someone has perfectly symmetrical features and you put perfectly symmetrical teeth on that face, you ruin their face,” he said.
What? Don't believe me? Just look at Regis' teeth!
