Garbage, did nothing at all. Don’t waste your money!
It is next to impossible to get it to come out of the tube, then it just keeps oozing out and wastes it. I used it for 6 weeks every single night and it did absolutely nothing. I did it on my top teeth and not the bottom so I would be able to tell even a slight difference. If it did anything at all it was to make my teeth and gums a little sensitive. Save your money. This doesn’t work any better than regular toothpaste!  If I could give it zero stars I would.
