It is understood that there is no age limit for orthodontics, but you need a doctor to judge the effect after correction according to the specific situation of your teeth, and then advise you to do it or not. At present, American brand Invisalign is very famous in Chengdu. The braces are invisible and transparent, and you can't see the whole tooth without looking carefully. If you pay more attention to fashion appearance and oral hygiene, it is recommended to choose invisible correction of big brands. Although the price is slightly higher, it has high cost performance and good follow-up service. If you are satisfied with the correction, you can put on the retainer, but if you want to correct it better, Invisalign can continue to correct it. Personally, I think this is quite attractive. I hope I can give you some reference.
