The cost varies greatly, ranging from thousands to tens of thousands. There are several main factors: first, the difficulty of orthodontics: if the teeth in the mouth are basically neat, the orthodontic expenses are of course relatively low. On the contrary, the greater the degree of tooth deformity, the higher the cost. The second is the way of correction. Traditional metal correction is cheaper, while transparent invisible correction is more expensive. It is recommended to go to the hospital for face-to-face consultation to determine the plan.
