Enamelast fluoride varnish is a xylitol-sweetened, 5% sodium fluoride in a resin carrier. Enamelast fluoride varnish's superior retention promotes enhanced and sustained fluoride release.^{1, 2, 3} Its sustained fluoride release and superior fluoride uptake means more fluoride is absorbed into the enamel over a longer period of time than other leading competitors.^{1, 2, 3}
