MI Paste Plus offers the same benefits as MI Paste but is enhanced with a patented form of fluoride to further promote re-mineralization and protect teeth from cavities and decay. 1 tube of MI Paste Plus contains 0.2% fluoride in 35 mL (40 g) of tooth paste. Apply MI paste to the teeth to treat dry mouth, enhance sensitivity, enhance tooth whitening, and reduce oral acidity from diet or pregnancy.
