Colgate Optic White Renewal Teeth Whitening Toothpaste, Enamel Strength, 3 Oz Tube, 2 Pack

Apparently whatever the whitening product is, is not good to use in your mouth.

I love this toothpaste, which is not yet available in Japan. The fact that it keeps my teeth white is wonderful.

Ordered numerous times. Works great. Use crest white strips too and oh the difference , game changer!

I love this toothpaste but you can find it cheaper at other stores.

Works well

That the price has now already dropped $2 from what I paid on Amazon for this product, which had been already discounted by $2 from list price of this revolutionary new formula should alert prospective customers that this product is not exactly flying off the shelves! I used all three tubes, brushing, as I always do, twice daily thoroughly. I ignored the hype, and judged the product as honestly as I could. The result is that I noticed no significant difference in whiteness. I also experienced absolutely no hypersensitivity reactions, small or of major concern. Of course, one has to be cautious about judging a product on the experience of one person; however, my conclusion is that for any person who has taken good care of their teeth, my expectation is that you will not reap any material advantage over Colgates standard, less expensive Optic White, or those of any of the major manufacturers, if used as directed. I am not submitting pictures supportive of my point of view, because they cannot be trusted as absolutely original these days. Please recall that in older people, the increased exposure of dentin under the thinning enamel imparts a normal yellowish coloration. For those who are not particularly attentive to consistently good dental hygiene, or if they be smokers/heavy coffee consumers, this toothpaste will likely not whiten your teeth any more than any quality toothpaste used as recommended by your dentist professionals to safely and gradually scour away the overlying stain. My purpose is not to engage in any defamatory verbiage here; however, my considered recommendation is that your interests will be best served to save your money, and, instead, to aggressively embark on a revised schedule and technique of dental hygiene, as recommended by your dentist and dental hygienist, using a quality, standard toothpaste which can be purchased for well less than even this reduced price!

My mouth got extremely dry when using it every day, I had to cut back to every couple of days use.

not worth the price
