Did You Know?
Orthodontics has been practiced since ancient times, but the elaborate techniques familiar to us today were introduced only in recent decades. Braces, retainers, and headgear are used to fix such conditions as crowding of the teeth and overbites. According to a 1939 text, "Speech defects, psychiatric disturbances, personality changes, . . . all are correctable through orthodontic measures", though many adolescents, having endured the embarrassment of rubber bands breaking and even of entangling their braces while kissing, might disagree.
