The two best hospitals for orthodontics are Peking University Stomatological Hospital. There is also Huaxi Hospital in Chengdu, where orthodontics is very professional and meets international standards. General orthodontic treatment takes three years and costs about 30 thousand yuan. If it is more complicated, it may reach 40 thousand yuan, which is the price of public hospitals and a relatively common price. If children are treated, the time will be shorter, 1-2 years, and the cost should be about 20 thousand yuan, but we must remember to do a good job in the maintenance of teeth after orthodontics.
