If your child’s incisor has not fallen out and there is another tooth growing inside, it may be a retained milk tooth or a supernumerary tooth. Depending on the circumstances, you may choose to observe or extract the tooth. 1. Observation: If your child’s incisors have not fallen out and there is a tooth growing inside, the growing tooth may be a permanent tooth. If the permanent teeth have just erupted from the gums, you can let the child eat more hard food to promote the root resorption of milk teeth, which is conducive to the eruption of permanent teeth. 2. Extraction: If the position of the permanent teeth has reached the occlusal plane, it is best to extract the milk teeth in this case, so as to avoid misplaced eruption of permanent teeth. If a tooth inside the incisor is a supernumerary tooth, it needs to be extracted in time, so as to prevent normal permanent teeth from erupting or erupting in the wrong position. If there is a tooth growing inside the incisor, there may be other reasons, so it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment.
