The growth of a small tooth between two teeth is a symptom of supernumerary teeth (also known as extra teeth). Extra teeth are teeth that erupt in addition to the normal teeth, which usually occur in the permanent dentition, and are more common in males than females, and can occur in any tooth position, but are more common in the maxillary teeth; the shape of extra teeth varies in size, and can often cause misalignment of the neighboring teeth or block eruption, and can even lead to the emergence of symptoms such as tooth-containing cysts. Multiple teeth must be extracted in time, i.e., under local or general anesthesia, using special oral extraction instruments (such as dental tines, extraction forceps, etc.) to complete the extraction of multiple teeth; and due to the anatomical factors of the differences in the multiple teeth, some of the multiple teeth will have a certain degree of difficulty in extraction, so it is recommended to consult the Oral and Maxillofacial Surgery Department for specialized treatment.
