Sensodyne Pronamel Isoactive review


Most of us, as we age, lose some of our teeth’s protective enamel layer and have sensitivity. I first noticed sensitivity on the right side of my mouth at the gum line at age 30. At that time, my dentist recommended “sensitive” toothpaste, brushing on the left side on my mouth first, a mechanical toothbrush and fluoride treatment for that area. From a recent Wall Street Journal article about Enamel Saving toothpastes, I gather my problem is a common problem.

For sensitivity, I use Sensodyne, it’s the toothpaste my dentist recommended years ago and the one he gave me free samples of. Sensitive toothpastes are not inexpensive. Usually, they are approximately 2-3 dollars more a tube. I imagine the Potassium Nitrate at 5% is the reason for the cost difference, but I’m not certain. Potassium Nitrate (saltpeter) is the active ingredient in all sensitive toothpastes. Previously, in the flavor lab, I did work on a project for a customer making a sensitive toothpaste. They felt the Potassium Nitrate needed to be “masked” (covered).

Typically, the Sensodyne toothpastes I use taste like anise (licorice). The Isoactive Pronamel is no exception, the aroma was strong in anise, vanilla and sweet mint. The taste was too sweet , almost sickening, and my mouth felt very warm. Spearmint, eucalyptus and citrus notes came out as I brushed and left my mouth feeling somewhat refreshed. The foam that the toothpaste formed was not pleasant. It was too thick and had to be spit out immediately; so I would not choke. The foam did expand to cover all the mouth quickly and reached all teeth in the mouth. After I brushed and swished, the sweetness wore off, and there was a bitter taste left at the tip of my tongue. It seemed to linger and was unpleasant.

The best part of this toothpaste is its ease of use. To dispense the toothpaste, one merely presses the button on the top of the can. There was no mess from “middle squeezes”. Once dispensed, the turquoise toothpaste quickly foamed to white. It’s pretty awesome to see.
