What are the advantages of pulling out second molars?

If the tooth is extracted under the indication of extraction, there are certainly advantages. The harm may refer to the complications of tooth extraction and the harm caused by dentition loss after second molar extraction. First, the common complications of tooth extraction include syncope, root fracture, gum damage, alveolar bone fracture, nerve damage, temporomandibular joint damage. The reactions and complications after extraction are mainly reactive pain, mouth opening limitation, and postoperative bleeding. Second, molars play the role of chewing and grinding food, incomplete dentition will affect food intake and chewing. Third, adjacent teeth lose support, wisdom teeth tilt forward, the first permanent molars tilt backward. Fourth, the first permanent molars tilt backward, and the second premolars lose normal abutment, resulting in food impaction, further development of caries, periodontal disease. Fifth, dentition defect can cause jaw teeth elongation, resulting in occlusal dysfunction, serious cases can cause temporomandibular joint disorder disease.
