Started using this about a year ago after doing tons of research on a “better” toothpaste.
The results have been amazing. No sensitivity anymore, and my dentist has been blown away by the results. She uses some sort of water blasting thing, and is able to turn it all the way up without any issues with me screaming in pain from sensitivity. Apparently everyone else would go nuts at the level she runs it! Plus, absolutely no cavities or other issues.
I’m sold. The higher cost of this offsets dental repairs easily. Pat 2018
