Fluoride Varnish can be applied in younger ages because it adheres to the teeth and is not swallowed. Our program begins Fluoride Varnish at 12 months and recommends 2 applications a year.
I do agree with Cindi. Fluoride varnish should be applied with the eruption of the first primary tooth at age of 6 months twice a year specially in high caries experice population.
I believe other points should be evaluated before proposing the application of fluoride to young children.
1. The patient has access to or is exposed to fluoride from other sources, such as public water supply?
2. The patient uses fluoridated toothpaste at home?
3. What is identified risk for the development of caries for each individual?
I see no problems in the administration of fluoride to patients at an early age, ie, from the eruption of the first teeth, provided that such preventive strategy is closely monitored and is combined with others, such as the control of biofilm.
The USPSTF, AAP, ADA, AAPD, and ASTDD recommend that that as a caries preventive measure, fluoride varnish be applied to the primary teeth of all infants and children starting at the age of primary tooth eruption.
