Problem analysis: Hello, according to your description, tooth extraction is a preparation work before orthodontic treatment, in order to make room for moving teeth and arranging dental arches neatly (that is, expanding the gap).

Guidance: Generally speaking, the first premolar needs to be extracted before orthodontics. Pulling out this tooth won't make you have fewer teeth than others. Please don't worry too much.

We think that orthodontics has little effect on your body, and the tooth extraction wound will heal itself after tooth extraction.

Will it affect the whole gum health in the future? Also, will the teeth lean forward a little, and will they get worse with age? If you do orthodontics, there is no problem. This should not change with age. Is it too much to pull out four teeth? . . . . And will it recur in the future? Because you can't grow any longer after pulling out your teeth. I am 2 1, and I am an adult. But if it is for orthodontics, I don't think it is a problem. My front row of dentition is uneven, and there may be dirt in it, which will corrode my teeth. Is it necessary to correct it? People around me say that my teeth won't protrude obviously. . .
