Whether general anesthesia is needed for pediatric polydontia needs to be discussed in different situations. If the supernumerary teeth have already erupted, then local anesthesia can be used, and if the supernumerary teeth are deeply buried, then general anesthesia may be needed, in addition, whether the child can cooperate with the surgery also determines whether general anesthesia is needed. Children with polydontia, also known as supernumerary teeth, is a phenomenon in which extra teeth other than the normal number of teeth (28 to 32) appear in the mouth. Multiple teeth may erupt into the oral cavity, affecting oral function and tooth alignment, or they may lie buried in the jawbone and cause jawbone cysts. The former is less difficult to operate and can be extracted under local anesthesia, while the latter is more difficult to operate and may require general anesthesia to operate. In addition, if the child can cooperate with the doctor, then local anesthesia can be chosen as much as possible to complete the surgery, if the child can not cooperate with the doctor, then only through general anesthesia to complete the surgery. If polydontia is diagnosed, please follow the doctor’s instructions for treatment.
