What is the single most effective way to prevent tooth decay in the public?

• A. Dental sealants for all children
• B. Community water fluoridation
• C. Regular brushing with water
• D. Using only fluoride toothpaste

Answer: (B)

Delivering fluoride to the community through the public water supply provides the broadest, most consistent protection against tooth decay. It delivers a small, steady fluoride dose to almost everyone who uses the water, regardless of individual habits or access to dental care, which translates into meaningful reductions in caries across all ages. It’s also cost-effective and scalable, making it feasible to sustain and extend across a population, which helps reduce disparities in dental health. Dental sealants, while highly effective for children at risk, target a specific subgroup and require resources to apply, so they don’t achieve the same broad public impact. Brushing with water lacks fluoride and offers limited protection, and relying on fluoride toothpaste alone depends on consistent use, which varies. So, water fluoridation provides the greatest overall benefit for preventing tooth decay in the population.
