@nickitrip: I have tried four different types of fluoride, free toothpaste, and Ollie is my favorite. my teeth actually feel extremely clean. And no longer have sensitive teeth after using this toothpaste. You should try it out for yourself. It’s definitely worth every penny. ##fluoridefreetoothpaste##hydroxyapatitetoothpaste##ollietoothpaste##toothenamel##brightersmile
