Just heard this short feature on NPR, talking about cosmetic dentistry.
Who knew that age (and gravity) even affects how youthful your smile looks! Here’s what a dentist interviewed for the article said:
“Every decade over the age of 30,” [Dan] Deutsch says, “you show a millimeter less of your front teeth.” Everything starts to sag a little, and the elasticity in the skin around the lips isn’t what it used to be. So, as gravity pulls its weight, more of the bottom teeth show.
“It’s an older look,” Deutsch says.
