I didn't like this. It did start to whiten my teeth somewhat, but it only seemed to whiten in patches which made my teeth look a little funny. I also didn't like the texture or the taste of the paste. I prefer the whitening strips just because I know that the results are going to come out even and because I only have to deal with that for 2 hours instead of each and every day.
This toothpaste does a great job cleaning my teeth. I do think it helps get your teeth whiter after a couple weeks of regular use.
