This toothpaste is really good for sensitive teeth. I have been using this for over a year, and it has helped a lot with my tooth pain. I've tried a few different brands (colgate, crest) and prefer this. The size is unfortunately small for the price, but since it prevents my tooth pain I'm ok with the extra cost. The toothpaste doesn't last my SO and me very long, maybe two months, but seriously helped me. Try to avoid the ones that say whitening though, I think they damage the enamel!
