FluroShield? Sealant reduces the chance of microleakage, because its patented adhesion promoter creates a combined chemical and mechanical bond to etched enamel when light-cured. Low water sorption increases resistance to washout. You get a bond so strong, it's greater than the fracture strength of enamel. FluroShield? Sealants are available in your choice of opaque white or tooth-colored to minimize visibility on the tooth surface.
