Aquafluor is a clinically tested fluoride varnish based on a watery acrylate resin. Aquafluor is recommended for the fluoridation and treatment of sensitive teeth and tooth necks. The emulsion is air-drying and builds an adhering film that absorbs moisture and releases fluoride for up to 24 hours. Thanks to this behavior, small concentrations of fluoride suffice for optimal fluoridation. When the varnish is completely soaked, the fluoride release stops and the varnish matrix dissolves from the tooth. Aquafluor contains 0,15 % pure fluoride.
