When two-year-old baby incisors erode, the following treatment measures can be taken: I. Correct the child’s bad habit of sleeping with a bottle, and reduce the intake of excessively sweet food and drinks. Second, strengthen oral hygiene cleaning, timely brushing and rinsing after meals, if necessary, application of dental floss, dental floss, etc., to remove the food fiber embedded in the adjacent surface. When superficial caries is formed on the labial or lingual surfaces of the incisors, the edge of the caries can be removed by grinding with a smooth turning needle and applying fluoride-containing medication to promote the remineralization of the enamel and avoid the expansion of the caries. Fourth, after the formation of caries on the adjacent surface of the incisors, low-speed ball drill can be applied to grind away the decayed tooth tissue from the lingual surface and use composite resin to fill the cavity. Fifth, when the incisor caries cavity is deeper and causes pulpitis, the pulp can be removed and root canal treatment can be completed. Fifth, when the incisors are extensively decayed and the filling material is not easy to be fixed, the resin can be made into a crown for restoration.
