Desensitizer. Shield Force Plus™ is a one component, light cured desensitizer.  Then dry the surface carefully by applying a stream of compressed air until the fluid film has disap- peared and the surface is no longer shiny. Treatment of dentin after mechanical tooth cleaning, scaling or root planing; treatment of tooth surface before and/or after teeth whitening; and treatment of prepared dentin for fillings.  It’s also useful as a cavity disinfectant, a rewetting agent and an adhesion promoter. The powder and liquid are mixed to form a slurry that is then applied to the affected area where it reacts with tooth structure to form hydroxyapatite. The result is instantaneous after the application and there is no restriction for the ingestion of liquid and solid food. It’s a non light-curing material and forms no coating on the dental surface.
