I've been using this product for 1 week, twice daily & I have developed extremely painful sores all over my tongue & my bottom lip is severely chapped & cracking. It is hard to eat & talk (which impacts my job as a librarian). I will be submitting my money back guarantee today! I just hope this clears up quickly!!

I have been using your Radiant Mint product for as long as I can remember. Both my wife and I like the product and use it exclusively. However, finding the larger tube sizes 5 and above in local stores or on line has become difficult. I can find 3oz tubes but that is about it. Even looking on-line, I can not find larger tubes 5oz or bigger. I prefer the 6.4 oz tube. Is there a reason for this??

[This review was collected as part of a promotion.] The flavor was okay, could have more mint but if you want a toothpaste that doesn't zing this is it. The texture is great, doesn't leave a film in my mouth and leaves my breath smelling fresh. Will continue to buy this product for its whitening capabilities and consistent quality.

I like the taste of the product but the packaging or tube that you have it in is for the birds. Right off the bat the lid broke off and therefore when you tried to set up the toothpast it didn't fit right. I do like that it is able to stand up when the lid is on it right but with the lid broken it sometimes doesn't seal and causes the past to dry out. Please look at putting on a different lid. Thank you,

After using once a day for 4 days I already notice a difference! My teeth are definitely quite a bit whiter. I can't wait to see what my teeth will look like after the 14 days that the box states that 80% of stains will be removed. It has a very fresh taste and makes my mouth taste and smell fresh for a few hours longer than my regular toothpaste. I don't think I would recommend using this more than once a day because although this does say that it does not harm enamel, it doesn't have the ADA seal. I love this paste!

I have been a smoker for 25 years. I am also a smoker who is not particularly fond of dentists, so I am not always as good at going as I should be. A few weeks ago my husband commented on the terrible stains on my teeth. I had noticed it already, but was kinda hoping it wasnt that obvious. It was. It was, in fact, downright awful. I decided to give the 3d tooth paste a try. It worked beyond any idea I had. After only 1 week of using it 2 or 3 times a day, my teeth are whiter than they have been in decades. I do wish I had a before and after picture to add to this, but as I don't, people will just have to take my word for it. Crest hit a grand slam with this product.

[This review was collected as part of a promotion.] This is a fantastic whitening toothpaste! The paste is smooth and not at all gritty. It freshens my breath and cleans my teeth well. It has a wonderful minty flavor and after using for a couple weeks now, my teeth definitely look whiter. Very happy with it.

I'm a smoker and a coffee drinker. I have used so many whitening products before, and they did the job, but the results never stayed. But this system's results have stayed! I used the 3D strips,the toothpaste and the mouth wash, and in conjunction with each other they removed 100% of my stains. My teeth used to have a slight yellow twinge to them, but now they are pearly white and have stayed that way for months. I continue to use the toothpaste and mouth wash daily. I am in love, thank you crest for finally giving us a product that works!

[This review was collected as part of a promotion.] Ive used this product for about a week now and I absolutely love it. I can tell that my teeth has lightened up a shade or two already. It tastes great and doesnt leave a weird after taste like some whiteners

I saw this product on a commercial and was instantly intrigued. After coming to this site and reading other reviews I decided to give it a shot. Being a smoker I was a bit skeptical, but after the first use there was a noticable difference! Ive been using this product for 3 days and would be satisfied if the progress my teeth have made was as far as it went, but I still have 11 days to go to see the full results and I am highly anticipating the outcome! I have tried other whitening products and have never seen such results, I recommend this product to anyone who wants whiter teeth, thank you Crest for providing such a remarkable product!
