How much fluoride is in MI Paste PLUS?
MI Paste PLUS contains 900 parts per million (ppm) fluoride ions a level just below that found in normal adult-strength toothpastes (1000ppm). While the remineralizing actions of the fluoride ions are well known, MI Paste PLUS with ACPF releases fluoride as well as calcium and phosphate ions, thereby providing all the three ions which are required for formation of acid-resistant fluorapatite. This level of fluoride also exerts some effects on the utilization of sugars as an energy source by dental plaque bacteria, which reduces their overall contribution to plaque fermentation.
