The shape of your face does not become smaller after wisdom teeth removal. The shape of the face is mainly determined by several factors such as the shape of the jawbone and the degree of development of the chewing muscles in the face, and there is no direct relationship with the presence or absence of wisdom teeth. 1. The shape of the mandible: the shape of the human face is mainly determined by the width of the mandibular alveolar bone and the shape of the mandibular angle, etc. Generally speaking, the wider the mandible is, the bigger the face is, and the bigger the angle of the mandibular angle is, the bigger the face is. Since the mandibular wisdom teeth are located at the end of the mandibular alveolar arch, the width of the alveolar bone before and after the removal of the wisdom teeth does not have any significant change, so it does not have much effect on the shape of the face. 2. The degree of development of facial masticatory muscle group: generally, people with excessive development of facial masticatory muscles, due to the hypertrophy of facial muscles and other soft tissues, the face is relatively large; while the degree of development of masticatory muscles in general, the face is relatively long and thin. Most of the wisdom teeth do not have normal chewing function, so before and after the removal of wisdom teeth, the development of human masticatory muscles will not be affected, and will not make the face smaller. The main purpose of wisdom teeth extraction is to remove the focal tooth to prevent recurrent inflammation, and cannot achieve the effect of making the face smaller, it is best to listen to the professional advice of the dentist before choosing the treatment.
