Using potassium nitrate, a naturally occurring, clinically proven active ingredient, Tom's of Maine has formulated this toothpaste to help soothe the pain of sensitive teeth.

They also use the natural ingredient glycerrhizin (from purified licorice root) to create a patent-pending natural foaming experience for ingredient dispersal without SLS. Glycyrrhizin needs no additional processing and is gentle on gums.

• SLS-free
  The foaming properties of glycyrrhizin replace the need for SLS (which may, for some people, occasionally be irritating) or an SLS alternative.
• Reduces sensitivity
  Uses clinically proven potassium nitrate, a naturally ocurring mineral, to reduce tooth sensitivity.
• Soothing brushing experience
  Xylitol (from birch trees or corn), gentle glycerin, and organic aloe for their soothing properties.
• Mild natural flavor
  Delicious natural flavor oils leave your mouth feeling clean and fresh.
