Clinically most of the Orthodontic braces treatment we can finish it in 1 year if it’s a non extraction case and some 18 months if it’s an extraction case . Most of the researches confirmed this ideal treatment duration schedule. But some literature shows slightly increased duration from 19 moths – 27 months. If it is a 2 phases of treatment like 1st phase of growth modification and 2nd phase of fixed braces ,it is almost normal. In Adult orthodontics, this treatment duration may slightly vary. If your orthodontic braces is a single phase fixed appliance then this 3 year is a very long time for braces. As an Orthodontist, my sincere advice is to consult an Orthodontist who is a specialist in treating tooth alignment problems.
