Quala 5% Sodium Fluoride Varnish is intended for the treatment of dental hypersensitivity and for the reduction of post-operative sensitivity. It is also ideal for use as a cavity varnish. The smooth, thin formula is easy to apply and dries to a natural tooth shade. The varnish sets rapidly in the presence of saliva and remains on tooth surface for up to 8 hours, optimizing fluoride uptake and reducing risk of fluoride ingestion. Contains Xylitol, which inhibits plaque formation.
