For many people in the U.S. and other western countries, crooked teeth are embarrassing. People spend thousands of dollars attempting to correct crooked teeth and get that "perfect" smile.
A growing trend in Japanese dentistry does exactly the opposite. The "yaeba" or "double tooth" in Japanese is a cosmetic dentistry trend that actually makes teeth appear less perfect by simulating crooked, protruding canine teeth. The New York Daily News reports that this procedure has become extremely popular among young women and adolescent girls.
