Active treatment time with orthodontic appliances can range from one to three years. It all depends on whether you have extraction or non-extraction treatment; your age and does it include an orthopedic treatment phase or not. There's no shortcut for orthodontic treatment, since teeth need time to move. However, if you listen to your orthodontist1s advice and instruction (e.g. wearing elastics and headgear as instructed) and act accordingly, this may shorten your treatment time considerably. In general, mild problems usually require less time, and some individuals respond faster to treatment than others.
