I love how this toothpaste foams up! Don't have to put too much on my toothbrush. This toothpaste made my teeth a few shades whiter. This was a good buy!

I do think it works on any tarter stained with coffee and the like. But as for tooth whitening, nope. I have a cap on top front upper tooth that was put in when I was 18-20 years old, now in my 60s and it acts like a gauge for this toothpaste and there is ZERO different. Again, if you have nice white teeth and drink coffee, tea, or smoke or chew tobacco, I believe this would help keep the stains off between your teeth cleanings. I don't do any of that stuff, but do love my coffee. I'll give it two stars for that. See photo added

Definitely whitens your teeth. But it taste horrible. They should have put a mint flavor.

Been using these products for a few years and have been pleased. They definitely whiten, and I have not experienced any sensitivity.

I've used all four tubes over time. No noticeable difference for coffee/tea stains.
