i don't get it. maybe my teeth aren't stained enough for this product, but i've used it for a month now with ZERO results. i don't even feel like my teeth are that clean! will not repurchase.

I'd been using GoSmile toothpaste for some time, and felt that it really wasn't doing anything for my smile any more, so when I saw this at Target I thought I'd give it a try. Wow! I too saw a difference after the first brushing, and my teeth keep looking whiter. This tastes great, isn't gritty, works, and is less than half the price of Go Smile. And it has fluoride, so you're getting benefits as well as whitening. I will repurchase again and again!

This stuff works! A while back my two front teeth suddenly appeared tea stained. No amount of brushing would remove the stain. Crest professional-strength white strips did not work. I was embarrassed and would not smile for months. Then I remembered smokers in my youth had used Rembrandt toothpaste. It was worth a try. Stains were eliminated on the FIRST brushing! Wish I had thought of it sooner...I could have saved myself months of embarrassment.

This toothpaste is amazing. I have professionally whitened my teeth but didn't feel like they were super white anymore. Most likely due to drinking coffee. I tried the whitening trays at home and they didn't make much of a difference. So, I heard about this toothpaste and tried it today for the first time. Literally, I noticed a huge difference the very first time I brushed. I brushed them again a couple of hours later and they are about two shades whiter on the very first day. This works so much better than the whitening trays and much easier to do. HIGHLY recommend.

I have only tried this twice (last night and this morning). I love this tooth paste. I imediately saw a difference. I have used other whitening tooth pastes and they didn't work. I am going to use this up and repurchase. I have tried all the whitening products available at drugstores, all the crest white strips, the up and up trays, the aguafresh, etc. This is a toothpaste that works better for me than the strips and trays. I bought this at Target for $7.99 and I am glad I tried this. I also bought the Rembrandt 2 hour whitening trays ($20). I am going to save those for later and see how white I can get my teeth with just the tooth paste. So far, very impressive. Seriously 2 shades lighter with just 2 brushes. I drink coffee, tea, don't smoke, but I eat things that stain your teeth. I drink at least 2 starbucks a day! My teeth were yellow. Now they are less yellow and I feel that after a straight week of use I will see a dramatic result. I will update this review with any pros and cons I come across.

paid around $8, which is a little expensive for a toothpaste

flavor is wonderful-- not too strong, but still minty

as far as whitening effects go, it really does the trick!

i've already re-bought twice, and will be doing so again and again in the future!

UPDATE 02/20/12:
we got a tube of this not too long ago that was super thin and watery. we just assumed that we got one of the "off" ones, these things happen. so when the NEXT one was like that too, we were really disappointed to find out that they re-formulated this. we tried a few other brands, tom's of maine, to name one, and it just didnt compare. we tried this agian, and it looks like they went back to the origional formula! yay! aparently people werent happy with the new one at all!

My teeth are so white!

I drink wine, coffee, and eat blueberries, but I have never had very yellow or discolored teeth. The thing is, a few of my teeth could be a bit brighter. In fact, my entire smile could be a little brighter. So, as I walked the aisles of my local drugstore, I picked this up. I thought it was just the regular Rembrandt whitening toothpaste, but I happened to pick up the Intense Stain version.

It was an awesome mistake! I use this toothpaste with my Oral-B Triumph Professional Care toothbrush and it is absolutely amazing. I've used several different toothpastes with my Oral-B and they all work well, but this Rembrandt toothpaste is the best I've tried! I brush my teeth when I wake up and before I go to sleep, as well as after meals on some days.

My teeth are so white, I love it! It's better than any whitening toothpaste I've tried. I have never gotten my teeth whitened, never used whitening strips, nothing. This toothpaste is what I rely on now, and it works!

Within the past few months I've started drinking 1 cup of coffee every afternoon (Nescafe Classico instant made w/skim milk - yummy!). I was surprised how much yellower my teeth became just drinking 1 cup a day. I don't really like using the white strips, except before special occasions. Saw this in the store & figured I'd try it. I saw a difference within 2 days. Don't think this will make my teeth super white but they are definately less yellow. I would reccomend this.

I have been using this toothpaste for years. I find it truly delivers. I don't smoke, drink red wine or eat blueberries, but I do drink alot of carrot juice. I think this toothpaste has really helped me maintain my Kilowhite Smile and I will buy 100x over til Im too old to have real teeth.

This is a great maintenance toothpaste to use in between whitening treatments. It has a brightening effect but you are only going to seriously whiter teeth with peroxide.
