Fluorodose is the top fluoride varnish of 2015, 2016 and 2017, according to the dental advisor. Clinicians love that it is smooth, not stringy or clumpy, so it reduces the chance of clogging vacuum lines. Patients love that it stays clear so there is no tooth discoloration. Fluorodose dries in seconds upon contact with saliva and remains on the tooth for 6 to 8 hours for optimum fluoride uptake. Fluorodose is cleared for treating dentinal sensitivity.
