[This review was collected as part of a promotion.] I was a bit leary at first to try the Crest 3D whitening therapy toothpaste with tea tree oil as it is charcoal and the toothpaste is actually black. I was pleasantly surprised by the taste and texture. Quite nice actually. It didn't leave my teeth black as I had feared. My teeth feel extremely clean after brushing. I would recommend this to everyone.

[This review was collected as part of a promotion.] I've tried so many toothpastes that claim to actual whiten your teeth, but all have failed and I've resorted to using strips. This is the first one that has actually helped. I wouldn't expect a miracle if you are hoping for multiple shades lighter, as it is a toothpaste after all, but I will say it actually DOES whiten your teeth with regular use. Not TOO minty, which I was concerned about. This one does the trick.

[This review was collected as part of a promotion.] This toothpaste has a good flavor. The toothpaste comes out black, but does not stain your teeth. I have been using it for over a week now and I already notice a difference in my teeth. My teeth are more white now. I would recommend this toothpaste to anyone.

[This review was collected as part of a promotion.] This toothpaste is great! First of all, for a charcoal toothpaste, it tastes really good. It's like a sweet mint. Second, I'm very happy with the results I've been seeing the last 2 weeks I've used it. It makes my teeth whiter, leaves my breath fresh and tastes good. I also like how it has tea tree oil, which is supposed to help fight bacteria, viruses and gum disease in the mouth. (Reason why it feels so clean and why my mouth feels so fresh after. You don't taste the tea tree.)

[This review was collected as part of a promotion.] I don't know if the charcoal is really doing anything. It's black when it comes out of the tube but unlike some charcoal products it doesn't have that color in your mouth. The flavor is good but unconventional.

[This review was collected as part of a promotion.] I have used this for about 2 weeks and I can tell a difference in the whitening of my teeth, they feel so clean afterward too. Just squeeze some on your toothbrush and brush normally. I would definitely recommend to my family and friends.

[This review was collected as part of a promotion.] I got this about a week ago and I think that it is a great toothpaste. It taste pretty good and makes my teeth feel clean. The charcoal aspect I think is making my teeth more white and I think it really helps!

Found this toothpaste about 8 months ago and fell in love. My teeth feel super clean & my mouth just feels so refreshed each time I brush! Best toothpaste I've used and will not use another after using this!

I love this one the most I've tried the regular charcoal and the fortifying enamel one as well and this one give almost instant results my mouth felt so clean for 48 hours I definitely recommend

This is the worst toothpaste I have ever used, it is like brushing my teeth with cake frosting. Colgate Optic whitening toothpaste sold here at Sam's is a superior product.
