If you’re seeking an effective, all-natural fluoride-free toothpaste, Simply Silver Mouthwash has got you covered. Our toothpaste contains Nano hydroxyapatite (nHAp), which aids in the remineralization of weakened enamel by restoring it nearly to its original state and also helps in preventing cavities.  This amazing ingredient was created by NASA and has been used by Japan since the 80s as their gold standard.
