First, the correction method. There are many methods, such as movable appliance, fixed appliance and extraoral arch appliance, and it is not necessary to wear orthodontic wire appliance for correction.
Second, the difficulty of correcting. If it is a plot, buck teeth, etc. It is more difficult to correct, so the charge is higher.
Suggestion: You 19 years old, and you are an adult. In this case, your teeth are arranged irregularly, which affects your appearance. We suggest that you do orthodontics, that is, wear braces to do orthodontics, about five or six thousand yuan. Generally speaking, it takes about two years (during this period, you should go to the hospital for a follow-up visit at least once every other month). In addition, it is necessary to wear the retainer for half a year after correction to maintain the correction effect and prevent the teeth from rebounding. thank you
