Dental caries in children need to be remedied by medication, other treatments, surgical treatments, and general measures. 1. Medication: Children need to be treated with fluoride such as 75% sodium fluoride glycerin paste, 8% stannous fluoride solution, etc. under medical supervision. In the case of milk teeth, children need to apply silver ammonium fluoride preparation to treat cavities as prescribed by the doctor. 2. Other treatments: For early caries, children need to cooperate with doctors to take remineralization therapy, fissure sealing and other measures for treatment. 3. Surgical treatment: if the child’s tooth tissue has already undergone substantial caries, it is necessary to choose surgical treatment, and the commonly used surgical methods include amalgam filling, composite resin direct bonding restoration, inlay restoration and so on. 4. General measures: children usually need to pay attention to the management of oral hygiene, rinse their mouth after meals, reduce the intake of sweets, and eat more food rich in dietary fiber. Usually, caries can be avoided to a certain extent by taking standardized remedial measures in the early stage of dental caries. Children need to go to the hospital in time, strengthen the daily life management, and cooperate with the doctor for active treatment.
