As someone who has had braces multiple times and am currently back in treatment, make sure you find an orthodontist who is hands on and actually takes the time to get to know you as more than just brackets and wires. Lot of orthodontists, at least here in the US, seem to be more about maximizing patients in chairs per day and making as much money as possible. My current orthodontist is the complete opposite and I much prefer the more personalized level of care compared to what feels akin to being moved like cattle through the system.
That bit of practical advice out of the way, good luck in finding and orthodontist and experiencing the thrill!
