Teeth growing into the gums may be caused by supernumerary teeth, ectopic eruption of normal teeth, etc., which can usually be treated by surgical extraction and orthodontic methods. 1. Multiple teeth: If it is a child’s tooth replacement period, X-rays should be taken to determine whether it is a multiple tooth or an ectopic eruption of a normal tooth. Generally for supernumerary teeth, most patients need to cut the gums to expose the tooth body, and then extract the supernumerary teeth so as not to affect the eruption of the roots of normal teeth. 2. Normal teeth ectopic eruption: If the normal teeth are ectopic eruption, the teeth can be corrected by orthodontic methods, such as maxillary cuspids are prone to ectopic eruption. If the adult patient’s teeth grow to the gums, it may be too small malformed teeth or blocked wisdom teeth, this situation may also need to be removed. There are many other reasons why teeth grow onto the gums, and it is recommended that patients be treated under the guidance of a medical professional to clarify the cause of the problem.
