There are definitely risks associated with the extraction of multiple teeth, and we have mainly erupted and buried multiple teeth. The risk of extracting multiple teeth is the same as the risk of normal extraction, and there are also some differences, the same is the invisible risk of extraction. Generally, the risk of extracting multiple teeth is mainly for children, who sometimes have difficulty communicating with each other and do not cooperate, so it is generally recommended to extract multiple teeth under general anesthesia, especially those that have not erupted. Because the surgery takes longer and the operation is more traumatic, the risk factor is definitely greater, so to consider general anesthesia surgery increases the risk of general anesthesia. In addition to the risks of ordinary tooth extraction, such as infection, pain, bleeding and other complications, there may also be complications of general anesthesia when extracting a multiple tooth. Accidental aspiration and choking of the child, as well as overdose of general anesthetic drugs can have more serious effects on the body. For extraction of buried multiples, we need to take CBCT to determine the growth of the teeth. The risks are, firstly, the extraction of buried multiples can easily damage the roots of adjacent teeth. Secondly, some of the buried teeth are close to the nerve canal, so it is easy to have nerve damage and local numbness after surgery. Third, the roots of adjacent teeth are damaged, resulting in pain, soreness and discomfort of adjacent teeth, and even the risk of loosening. Root canal treatment is required for some of the adjacent teeth damage.
