Contains fluoride for cavity prevention, silica for whitening, soothing aloe, and glycyrrhizin from licorice root for natural foaming. Dear friends, Our Clean & Gentle Care toothpaste leaves your teeth and mouth feeling clean and fresh - without using sodium lauryl sulfate (SLS). SLS foams and disperses ingredients but for some may cause mouth and gum irritation. Our breakthrough formula uses the gentle ingredient glycyrrhizin (purified from licorice root) for natural foaming and fluoride for cavity prevention. Give it a try, and please let us know what you think! Kate & Tom Chappell. SLS-free. Natural glycyrrhizin from licorice provides a low-foaming experience. Soothing brushing experience. Contains Xylitol (from birch trees or corn), glycerin, organic aloe, and mild natural flavor. Fights cavities. Fluoride remineralizes soft spots on teeth before they turn into cavities. Gentle whitening. Silica (from sand) whitens without bleaching ingredients or harsh abrasives. Sensitive to the planet. We use recycled and recyclable packaging and invest in wind energy to power our factory. Naturally, it works.
