'Yaeba' - 'double tooth' in Japanese - is a trendy cosmetic procedure for Japanese women to accentuate their canine teeth. Some say the imperfection makes them more approachable, but others worry it is sexualizing a childlike look.

In the U.S. people aim for perfectly straight dentures, but an entirely different trend has taken off in Japan. Many teenaged girls have undergone dental procedures called yaeba to elongate their canines, producing a fang-like imperfect - and some say childlike - appearance. Yaeba means "double tooth" in Japanese. The yaeba look is achieved when molars crowd the canines and push them forward. Many younger children are familiar with the schoolyard taunt "snaggletooth," which is common before orthodontics are put in place in the teen years. But numerous young Japanese women with "snaggleteeth" paid for it.
