I varies from person to person: everyone can accept this factor. After all, everyone is a different individual, and the conditions for personal correction naturally vary widely, such as ① the degree of tooth deformity+② the type of tooth deformity+③ whether there is inflammation or tooth decay in the mouth+④ whether tooth extraction is needed+⑤ age ... and so on, which leads to different difficulties and durations of correction, and naturally different prices.
Two. It depends on the material: There are many kinds of orthodontic braces, such as ① traditional steel braces+② semi-invisible ice crystals+③ semi-invisible ceramics+④ totally invisible ... and so on. Different materials of orthodontic braces will further affect aesthetics, comfort and correction time. There will be a certain gap, and the revised price will naturally be very different.
Three. Off-site: As we all know, the consumption level of first-tier cities is higher than that of second-tier cities, so the revised price of first-tier cities will be higher than that of second-tier cities. This is a common phenomenon, and we should understand it from the aspects of clothing+food+shelter+transportation.
