Henry Schein Acclean 5% Sodium Fluoride Varnish is simple and easy to apply. Premeasured unit-dose cups fit into the enclosed finger ring, and the varnish applies easily with the included Microbrush applicator. Pearlized white varnish sets on contact with saliva and dries to a natural tooth color. Henry Schein Acclean 5% Sodium Fluoride Varnish is formulated with only natural sweeteners and xylitol and delivers one of the highest fluoride concentrations available (compared to nonvarnish fluorides).
