Hello, if teenagers do orthodontics, the price will be around 12000 yuan, and the adult orthodontics will take a long time and be difficult, so the price will be around 15000 yuan. If invisible orthodontics is used for treatment, the price will be relatively expensive. Orthodontics usually requires wearing braces for one to two years, because the orthodontic time needs to be determined according to the degree of tooth deformity and the adjacent relationship between teeth and surrounding normal teeth. Moreover, during the period of braces, we should pay attention to the falling or loosening of steel plates, maintain oral health, and avoid eating hard food in our diet.
