Because everyone's degree of tooth deformity is different, the difficulty of correcting teeth is different, so the cost of orthodontics is also very different. Orthodontics includes examination, X-ray, design, tooth separation, bracket attachment, and some may need tooth extraction. Adult orthodontics generally takes about one and a half to two years, and a follow-up visit is needed during orthodontics, so how much it costs to do orthodontics is also very different. If the degree of tooth deformity is slight, it will be less difficult and the cost of orthodontics will be relatively low. The more serious the tooth deformity, the more troublesome the tooth correction will be and the higher the cost of the tooth correction will be.

Stomatologists in the Second Affiliated Hospital of Heavy Medicine pointed out that the best age for orthodontics is 12- 16 years old, which is called the "golden age" of orthodontics. At this time, the child's deciduous teeth have all been replaced, and they are in the stage of growth and development, and the plasticity of teeth is relatively large, because it will be easier for children to orthodontically, and the cost of orthodontics will be relatively low. Relatively speaking, adult orthodontics will be more difficult and the cost of orthodontics may be higher.
