ColgateOptic White Purple Toothpaste for Teeth Whitening, Helps Remove Surface Stains and Polishes Teeth, Enamel-Safe Mint Paste, 4.2 oz

I can't believe this really works, good quality, highly recommend it

Works great for whiting teeth! Doesn't taste bad either

Love this toothpaste to assist in whitening teeth. If you are a coffee drinker, this will help in removing coffee stains.

My teeth feel clean after I use this; not sure there is anything magical about a purple toothpaste or this one in particular. I will continue to use it until it is gone, as it is still a good toothpaste. I don't think it has any advantage over any other good quality whitening toothpaste.

Is very good product, My teeth are not very good, but I feel that this product helped improve it and, above all, whitened it

So I have been using a variety of different Colgate Optic White toothpastes for several years. As per usual, some work better on my teeth than others but all give decent results. This particular "purple" version does an outstanding job on whitening my teeth and is the best Colgate whitening toothpaste that I have ever used. ..... but... That being said, after i used it the first time the inside of my mouth, my tongue and lips felt a little sore as if something had burned them slightly. Unfortunately, every time I use this toothpaste and see the beautiful white results, within a few minutes the burning begins and I am convinced that there is something either corrosive or caustic among the ingredients that while highly effective at whitening teeth are also burning and hurtng the inside of my mouth and my tongue. My tongue also turns purple and stays that way for quite a while. Not a good look . . . . . So maybe I am sensitive to the ingredients and I cannot tolerate it, which is my theory because I have not seen anyone else make note of burning in their mouth as part of their review of this product. I am now going to go back to the non-purple Optic White version and hopefully, all will be well. As I stated above, this provides a very fast and effective whitening of my teeth and it is pretty impressive. Hopefully all of you who try this out will not have the problems I have had. I wish you all good luck.

This really works. In just a few uses, I noticed my stains removed, teeth brighter and whiter. Nice flavor. It feels really refreshing too. Freshens breath. Great value for the price. We will definitely continue buying this product regularly.

Great as expected!!
