Orthodontics may change the shape of your face. Orthodontics itself can have some effect on the shape of your face, and many people find that their face shape changes slightly after orthodontics, which is normal. 1. Orthodontics is a way of straightening the teeth, usually by wearing braces, which slowly apply pressure on the teeth to bring them back to their normal state and align them more neatly. 2. If more teeth are extracted during orthodontic treatment, then the impact on the shape of the face will be greater. However, if only one or two teeth are extracted, then there will not be a serious impact on the orthodontic change of face shape. If multiple teeth need to be extracted for orthodontic treatment, then the patient should consider it carefully, because when multiple teeth are extracted for orthodontic treatment, it will definitely have an impact on the face shape and may change the shape of the face. 3. If there is an irregularity or multiple teeth in the whole row of teeth, the teeth need to be extracted before orthodontic treatment. However, if individual teeth can be corrected with crowns, there is no need to worry about the appearance of changing the shape of the face. Patients who need orthodontic treatment can choose crowns or braces to straighten their teeth according to their own situation under the guidance of the doctor.
