What does the USPSTF recommend for infants and children regarding fluoride varnish?

The United States Preventive Services Task Force (USPSTF) recommends applying fluoride varnish to primary teeth beginning at the time of tooth eruption. This recommendation is based on the evidence that fluoride varnish can significantly reduce the risk of dental caries in young children. The application of fluoride varnish is an effective preventive measure, especially since children, upon eruption of their primary teeth, are at increased risk for cavities. The recommendation emphasizes early intervention to promote oral health from a young age, rather than waiting until a child is older or has more teeth present. This proactive approach is crucial for establishing a foundation for good dental health throughout their lives.
