I went to Bailey Dental Clinic, and the correction cost me more than 10,000 yuan. Dr. Ding's skill is really good, and now he is replacing the retainer. In fact, after the technology of orthodontics is mature, the effect of orthodontics has been improved a lot. Personally, if you choose a hospital, you can set it according to your own needs. Doctors, technology, services, materials and prices are different in each place, which will also affect the effect, so there are many aspects when considering it.
