The breakthrough Fire-Freeze formula works in two ways. First, the red gel gives a mild, warm feeling that thoroughly cleans the mouth of germs. This red gel contains Zinc Sulfate, a special active ingredient that kills odor-causing bacteria.

On the other hand, the blue gel gives the mouth an intense cooling sensation for long-lasting fresh breath. This blue gel, with a state-of-the-art, patented cooling molecule, leaves you with an intense cold feeling that lasts for hours and hours.

The red and blue gels come together to give a one-of-a-kind brushing experience. This is made possible by a Chemosensory technology that delivers the two opposite sensations in just one brushing.
