The incorporation of special additives minimises plaque formation and enhances remineralisation to further reduce sensitivity. The high water content of the gel reduces dehydration of the enamel and decreases patient sensitivity. This reduces the tacky feeling and drying effect of the gel in turn reducing sensitivity further. The high viscosity gel ensures it can be easily and securely placed into the tray and remains in the tray for the entire procedure. The pleasantly flavoured spearmint gel is both fresh and long lasting.
