I got this after seeing in a ad. I don't believe I saw a difference in one day. But I do love it. It gets your teeth really clean, like when you go for a cleaning. With a nice fresh breath taste when you're done.

I give this a 4 star. It immediately started making a noticeable difference on surface stains. After using it for 3 weeks I'm unsure if it's whitening anymore or not.

I've bought the three pack of this twice, figuring that maybe it was just a little longer to whiten my teeth. I brush twice a day, using your product, and nothing has changed. Don't worry it's pointless for me to ask for my money back at this point, but you really need to fix that marketing or do some market testing because from my standpoint and experience, this is false advertising

I LOVE this toothpaste! I have been using it for over a month, and my dentist even asked me "when did I get my teeth bleached, and who bleached them". That being said, I didn't give it 5 stars because the dispenser pump is absolutely horrible. It takes two hands to work the pump mechanism. Crest, PLEASE offer a regular cap. The pump idea was a bad idea

The delivery system needs improvement due to constant clogging of the opening and at times difficult to depress the plunger Have been using the Deep Stain Remover for a week now and haven't noticed a marked improvement on the whiteness of my teeth, especially the lower jaw. Any suggestions for an alternate choice without that plunger?

This product works great! My teeth are whiter and brighter than they've been in years even after professional cleanings. Would highly recommend.

I love the toothpaste and the results (my husband's teeth have gotten noticeably whiter since beginning to use it). I also like the taste. But the reason for the 'average" rating is because of the pump, which does not work well and is not at all consumer friendly Why oh WHY can't we buy this toothpaste - and formula - in regular larger normal toothpaste tubes? The kind we can squeeze up from the end when they start getting low. These pump gizmos make me feel as if once it starts to run out at least a tenth of the product is going to waste.

Didn't I work the way it was noted on the package

I have sensitive teeth, but this toothpaste does not bother my teeth at all. I use it morning and night, and I’ve seen the difference!

This toothpaste tastes good and seems to clean well but if there has been any whitening it is imperceptible after 2 weeks of use.
