You mean a dental hospital or a dental clinic. If it is a stomatological hospital, it is better, but it is difficult to register and the service is poor. Repair or tooth extraction treatment is better. If large-scale treatment is involved, it is best to go to a private clinic, such as orthodontics, and you can go to the Debir dental clinic in the Italian style area. They have orthodontists in Beikou, and orthodontists in Tianjin are basically authoritative. In addition, they are also the training base for orthodontists in Invisalign and many orthodontists in Tianjin.
