It depends on the age of the patient and the arrangement of teeth. My child is doing orthodontics in Daqing Liangdeshuo Stomatological Hospital. I spent 4000 yuan to go to a hospital in Ranghu Road, Daqing, and asked for 7-8 thousand yuan. We have been doing it for 2 years, and the effect is very good! So the price is different. You should look at the doctor's qualifications and personality, and more importantly, technology! !
