Why is fluoride varnish applied during well-child visits?

Fluoride varnish is applied during well-child visits primarily to prevent dental caries by strengthening tooth enamel. This preventive measure is essential, especially in young children, as their teeth are still developing and more susceptible to decay. The varnish contains concentrated fluoride, which adheres to the teeth and enhances the remineralization of enamel, making it more resistant to acid attacks from bacteria that cause cavities.

Regular applications of fluoride varnish are a key component of pediatric oral health care, helping to reduce the incidence of tooth decay and promote overall dental health from an early age. This practice is supported by various health organizations, advocating its use in routine dental care for children to ensure they maintain healthy teeth as they grow.
