Orthodontics is a specialty field of dentistry that deals primarily with malpositioned teeth and the jaws: their diagnosis, prevention, and correction. An orthodontist is a specialist who has undergone special training in a dental school or college after they have graduated in dentistry. It usually takes almost 24 months to complete the treatment. The treatment includes the adjustment of braces every 6 to 8 weeks by the orthodontist. Depending on the needs of the individual patient, there are multiple methods for adjusting malocclusion.
