I had a great doctor who was my Orthodontics when I was a child. 
I would like to think so, after all Orthodontics have been around for more than 2000 year!
Yes, and they have made great advancements in the technology of orthodontics. 
That is correct, since Orthodontics is directly involved with it's origins in medicine there have been enormous advancements in the century.
As a child I can remember how much pain I was in the tightening process of Orthodontics with rubber bands. 
Understandable, the use of dental braces to correct underbites, as well as overbites, deep bites, and crooked teeth could be a painful process.
I suffered from an overbite as the a 10 year old. Do you have an overbite? 
I do not any longer, as a 12 year old myself I had dental braces to help re-position my teeth in relation to my bite.
I wish they had those invisible brand braces when I was that age. Would have been lot less social silliness. 
Likewise, the recent advancements in these invisible braces have certainly made overbite correction more discreet.
