It should be possible. Shanghai's orthodontic technology is also world-class. Foreign dentists can continue to help you with regular maintenance and review. My friend is also doing orthodontics recently. In the United States, orthodontics belongs to tooth beauty, which is basically at its own expense, and the cost may be more expensive than that in Shanghai. The total cost of orthodontics is about 5000 dollars. American doctors generally don't charge for each time, but for the whole orthodontic process. Your best way is to ask your American family to make an appointment for you first, and then start orthodontics when you arrive in the United States.
