The cost of orthodontic treatment for adults may range from 4,000 yuan to 12,000 yuan. The specific analysis is as follows:

The cost of orthodontic treatment for adults will be affected by many factors. Among them, if you choose ordinary wire braces, the cost will be around 4,000 yuan. However, if you choose invisible silicone braces, since they will not affect the aesthetics and have better correction effects, the cost is likely to be around 12,000 yuan.

Generally speaking, it takes about 3 or 4 years for adults to recover from orthodontics. During this period, they need to go to the hospital for braces adjustment at regular intervals.
