What Does Fluoride Do for Your Teeth and What Are Side

Fluoride concentrations in toothpaste are measured in ppm or percentages. Ppm stands for parts per million and refers to the number of fluorine particles per million. If it says 900 ppm of fluoride on the tube, that means there will be 900 mg of fluoride in 1kg. The higher the concentration of fluoride, the better the paste restores enamel.
