So the “big face” at puberty, round face starts to become thin, of course, this process will continue until about 35 years old, which is a good phenomenon, small face is what every woman likes. The orthodontic extraction will also produce similar changes, the face will become smaller after the orthodontic extraction, only faster, the orthodontic correction of one or two years to become smaller. There is only one case where tooth extraction orthodontics should be done with caution. Women with large cheekbones and wide cheekbone positions may appear to have higher cheekbones when their cheeks are smaller, and if they do not like their cheekbones too high, the correction needs to be combined with cheekbone reduction surgery. But people with a western cultural background tend to prefer a more bony face, there is no problem.
