Q. Hi, I am 41 years of age and have been to a couple of people to help me straighten my teeth. 1st was an orthodontsist who has offered to fit traditional braces (tooth coloured upper, and steel lower) which should take approx. 12 months. 2nd was a dentist who has took on the 6 month smile method (which would be tooth coloured upper and lower). Is there any disadvantages of the 6 month smile method against the traditional, and how would I be able to find out if the dentist is suitably qualified?
