Patient: A dental film was taken during a physical examination and it was said that it was determined to be a multiple tooth, and the doctor’s advice was to look at it again after a while. Now that school is about to start, I took him to another hospital and the doctor said that this is not going to grow out, although his milk teeth have not fallen out yet, but now this multiple tooth has affected the growth of the permanent teeth at the root, the permanent teeth have been found to be deformed, and surgery is needed, saying that local anesthesia may be too much for the child to handle and that general anesthesia is needed. What will be the effect if I don’t remove it now? Wang Minyong, Department of Pediatric Dentistry, Peking University Stomatology Hospital, Second Outpatient Department: X-rays are the key information in the treatment of multiple teeth, I have not seen your films, so it is not easy to say, but generally speaking, multiple teeth can be extracted under local anesthesia. As for whether the permanent teeth are affected or not, it depends on the relationship between the two positions, which is not easy to determine by ordinary X-rays, and special dental CT may help to diagnose. The timing of extraction also depends on whether or not the multiple teeth will affect the development and eruption of permanent teeth, if so, they should be extracted early; if not, they can be extracted at a later time after the permanent teeth erupt. Wang Minyong, Department of Pediatric Dentistry, Peking University Stomatology Hospital, Second Outpatient Department: The position of the central incisor above the supernumerary tooth is a bit crooked from the X-ray, which may be caused by the pressure of the supernumerary tooth, my opinion is to extract the supernumerary tooth as soon as possible. This is only a minor surgery, which can be performed under local anesthesia in the outpatient clinic.
