It is recommended to go to a regular hospital, including Shanghai Baishi Dental Clinic. You can go now. I heard that the price is reasonable. Orthodontic precautions 1. Brush your teeth frequently, especially before going to bed, after meals and after snacks, and pay attention to oral hygiene. You can use mouthwash if necessary (it is sold in major supermarkets). The cost is about 2000 to 3500, depending on local consumption standards and materials. 3. If the tooth is extracted, the correction time will be longer, because it takes time to close the teeth (correction depends entirely on physical strength).
