Children with large gaps between their teeth can take the following treatment measures: First, when caries is formed on the adjacent surfaces of the teeth and food debris is easily retained, the decayed tooth tissue can be removed by grinding down from the jaw surface, and composite resin can be used to fill in the cavities after preparation, so as to restore good neighboring relationships. If the child’s labial or lingual tie is too low, which affects the closure of the incisor gap, the tie can be repaired in time, so that the gap between the incisors can be gradually reduced. If the X-ray shows that there is a supernumerary tooth in the alveolar bone, causing the crown to be tilted, the supernumerary tooth can be extracted under general anesthesia. Fourth, if there are more gaps in the dentition after the replacement of milk and permanent teeth, the gap can be eliminated by orthodontic treatment, pulling all the teeth to move and shorten the dental arch. If supernumerary teeth are formed, veneers or full crowns can be made to restore the normal anatomical shape.
