1 Dr Charles Tweed was the first certified orthodontist in the US. 2  The first braces were constructed by Pierre Fauchard in 1728. 3  Fauchard's braces consisted of a flat strip of metal, which was connected to teeth by pieces of thread.
He noticed that if he didn't wear his retainer for a few days, his teeth shifted slightly -- but the plastic retainer soon moved his teeth back the desired position. In 1997, he and Wirth applied 3-D computer imaging graphics to the field of orthodontics and created Align Technologies and the Invisalign method.
