@nickitrip: 10% Nano-Hydroxyapatite to help fill in your teeth enamel. Great flavor, my teeth feel so smooth and clean. I’ve tried other fluoride free toothpaste but Ollie has worked the best with the surface of my teeth & the sensitivity. Well worth the money. #fluoridefreetoothpaste #sensitiveteeth #oralhealth #brushyourteeth #summervibes
