Methods for Preventing Dental Caries in Children

Childhood dental caries is a preventable, biofilm-mediated, sugar-driven, multifactorial disease that can cause pain, infection, impaired nutrition, sleep disturbance, school absence, and substantial treatment burden. Background: Current prevention is based on repeated caries-risk assessment, twice-daily use of age-appropriate fluoride toothpaste, reduction of free-sugar frequency, establishment of a dental home in infancy, professional fluoride varnish, pit-and-fissure sealants, silver diamine fluoride, and minimally invasive care. Objective: To review evidence-based home, clinical, family, and school-level methods for preventing caries in children and to identify common causes of programme failure. Materials and methods: A narrative review of AAPD manuals, WHO guidance, USPSTF recommendations, systematic reviews, and selected clinical guidelines published or updated through 2026. Interventions were assessed by mechanism, effectiveness, frequency of application, feasibility, safety, and monitoring requirements. Results: No single product can compensate for frequent sugar exposure, inadequate brushing, or absent follow-up. The minimum effective package is supervised brushing twice daily with fluoride toothpaste, practical reduction of free-sugar frequency, risk-based professional fluoride, early dental attendance, and sealant assessment for newly erupted molars. High-risk children may additionally benefit from repeated varnish, 38% silver diamine fluoride, and minimally invasive treatment. Conclusion: Prevention succeeds when the family receives a simple, measurable plan and clinicians monitor lesion activity, behaviour, fluoride exposure, sealant retention, and recall attendance over time
