Whether orthodontic extractions will collapse the face depends on the patient’s individual situation and the doctor’s plan. Most patients who undergo regular orthodontic treatment will have their doctor decide whether or not they will have their teeth extracted and what position they will be in afterwards, depending on their facial shape. In this case, most patients’ faces will not collapse, but some patients may have brace faces during the treatment process. In the orthodontic process, if the patient’s masticatory muscles are used too little, the patient eats significantly less, and the muscles may atrophy, and when the atrophy of temporal and occlusal muscles occurs, it will lead to brace face (face shape change in the orthodontic process). Patients may think that the face shape has collapsed, if patients practice chewing more, this situation will be better improved, even after the removal of braces, if patients chew more gum, or chew more tough food, the muscles may be plumped up again.
