Zhejiang, I have been to two cities for consultation. The total amount of adult correction is 2.5w+, and the treatment fee varies from 1.8W-2W according to your correction period. In addition, you may have to have your teeth extracted or have your teeth planted. Blood drawing and filming add up to this price, which may even be high. Every pair of braces needs to be changed, and you need to add money. The cost of invisible orthodontic bare braces is close to1w.
In Nanjing, Jiangsu Province, the adult correction fee is 2w, which is similar to the above. So everyone's expenses are different according to their own situation.
Cheaper braces are also available, such as ordinary metal, metal self-locking, ceramic, ceramic self-locking and invisible, which is probably the price increase.
In a word, I think the cost is not small.
