Adult orthodontics, 3000 to 5000. It mainly depends on what materials you use, such as porcelain crowns, which are also more expensive, more than 10 thousand. How old are you? Orthodontics for children is relatively cheap, generally around 34,000 to 1000, while that for adults is relatively expensive, around 67,000 to 20,000, depending on your orthodontics. I used to look at Bell's mouth, where the orthodontic effect would be better.
