Orthodontic extraction of four teeth is not significantly harmful in old age.
Orthodontic tooth extraction is usually the extraction of the upper and lower four first or second premolar teeth, that is, counting from the first incisor, located in the fourth or fifth teeth. Compared to the cutting function of incisors, the piercing and tearing of food by tiger teeth, and the grinding of fine food by molars, the functions of premolar teeth are not so prominent, so the function will not be affected much after extraction.
For some patients with poorly aligned teeth and severe malocclusion, the harm of teeth misalignment is rather greater, such as crowding of teeth will hinder the implementation of oral hygiene measures, resulting in dental caries and gingivitis. The chewing efficiency of the patients with the circumcision decreases, affecting digestion, absorption and so on.
Through orthodontic correction of malocclusion, have a beautiful, straight teeth, not only conducive to the health of the dentition, periodontal tissues, but also greatly enhance the patient’s self-confidence.
