    Great product

    I really like this product. It makes my whole mouth feel clean and fresh with no dryness after brushing and no weird aftertaste that I did get from my old toothpaste brand. It’s environmentally friendly, which is a bonus. This is my new go to brand.

    Love it!!!! My mouth has never felt or tasted cleaner and after just 1 week of using this twice a day, my tooth sensitivity is even better than it was when I was using Sensodyne Pronamel Repair by Colgate. Love that I finally found a fluoride free toothpaste that actually helps my sensitivity and overall dental health and cuts down on plastic waste/pollution!! Yay!!!!
