I am an orthodontist. The general orthodontic advice is 13/ 14. The earlier you change your teeth, the better. Compared with the current orthodontic technology, the age of 19 is normal. There are many orthodontic patients in their forties in our hospital, and the largest orthodontic patient in China is in their sixties. The cost of common household appliances in Ganzhou is about 3000-5000, which usually takes two or three years to complete; There is also a new movable wing appliance, which can be completed in about one year, but the cost is a bit high, at 8000- 13000. Our Wei Hua Stomatological Hospital specializes in this kind of movable wing correction, and holidays are endless. Welcome to consult when you are free! ! !
