Tom's of Maine uses the same, FDA-allowed, ingredient to fight tooth
sensitivity as the leading brand. We source naturally occurring nitrate ore for
our active ingredient Potassium Nitrate, clinically proven to help reduce and
relieve your painful sensitivity caused by exposed dentin on the surface of
your teeth. Some consumers prefer a product without fluoride, which is why we
are pleased to offer a fluoride-free version of our sensitive toothpaste!
