Let's discuss whether the whole tooth can change the face shape first.
First, orthodontics cannot change the position and shape of mandible.
This picture was published by Dr. Xu from Peking University Stomatological Hospital in Zhihu. He said that the position of the white circle is the position of the wisdom teeth, and there is still a certain distance from the mandible, so no matter how long your wisdom teeth are, pulling out the wisdom teeth will basically not change the position and shape of the mandible, that is, it will not change the width of the facial bone.
Many articles on the internet say that orthodontics can't change the face shape. I think it means that you can't change the shape of the mandible. To completely change the face shape, it is necessary to do mandibular angle surgery and adjust the shape of the mandible.
Second, orthodontics can change the position of the chin.
The whole tooth can change the shape of the chin, because it can improve our occlusion problem and keep your chin in the right position. Viewed from the side, the effect of the whole tooth is obvious, which improves the problems of convex mouth, concave chin or protruding chin.
The whole tooth changes the face shape, probably because it changes the position of the chin. It seems that I have changed from a round face to a melon face or from a long face to a round face.
Third, orthodontics can change facial muscles.
Although the whole tooth cannot change the position of mandible, it can change the size of masseter muscle. Just now, I said that the whole tooth is very helpful to improve the occlusion problem, and the corresponding masseter muscle may also change after the occlusion is improved.
The face-lifting needle acts on the masseter muscle, so changing the masseter muscle is likely to make your face look thinner.
However, the face-lifting needle is only effective for people with smaller cheekbones and larger masseter muscles, so it does not mean that all people will face-lifting after finishing their teeth.
In addition, too much tooth extraction will cause facial muscles to collapse a little, which will make you feel that your face has changed.
Although tooth extraction with braces is likely to help face-lifting, these are some extra functions. Don't pull out your teeth for face-lifting, put the cart before the horse. If you have protruding teeth, lateral teeth and occlusion problems, don't hesitate. You'd better have orthodontics!
