The risks of extraction of buried teeth can be said that in any surgery there are risks, but the chances of their occurrence are relatively low. There are definitely risks associated with the extraction of buried teeth, but they are certainly not life-threatening. The main risk is that the important anatomical structures around the tooth may be affected. For example, if the maxillary buried tooth is close to the maxillary sinus, or if there is an adhesion between the root of the tooth and the bone of the maxillary sinus floor, the extraction of the buried tooth may cause a perforation of the maxillary sinus, resulting in a connection between the oral and nasal cavities, and may cause inflammation of the maxillary sinus, but this can be repaired, and the results are very good. The operation of this surgery is not complicated, for the mandibular buried teeth, especially the buried obstructed wisdom teeth, some wisdom teeth roots are closer to the lower alveolar nerve, in the process of extraction the roots may cause compression of the nerve, or pulling out the possible post-operative lip will appear a numbness. Of course, most of this situation can be recovered, and the recovery time is generally within six months, of course, a small number of people may not be able to fully recover the symptoms of numbness, but also to a large extent to reduce the scope of this numbness, his sensation will also be a large degree of recovery, of course, the nerve damage it only has abnormal sensation, for this facial movement, speech, eating, appearance are There is no effect on facial movement, speech, eating and appearance.
