When I started using I was skeptical. I was greatly surprised. After using optic white tooth paste for 2 days I was so surprised. My teeth were whiter they felt cleaner and my breath was extremely fresh. I'm using it day and night. My teeth feel clean all day long. I love this tooth paste and I would definitely buy this but it is pricey. That is the only con I have about this product. It is a great toothpaste!!

This toothpaste makes my teeth and mouth feel very clean after using it. I have repurchased this many times many because of the great taste and refreshness I get from it. I don’t notice it whitening my teeth like it claims however. But I would recommend it if you are just using it to maintain a clean mouth!

By far my favorite whitening toothpaste. We can all use a pick me up from time to time so we use this and once a week,I use the crest strips for 10 minutes to keep my smile nice and approachable! Always spread smiles,Crest Definitely helps me with that

I was not a fan of this toothpaste. It didn't get my teeth any whiter and I didn't feel like it left my mouth feeling very fresh or clean. There are much better toothpastes out on the market that I would chose over these. I would not buy this toothpaste again even if it was on sale for half the price. 

I really liked this product at first. Within the first two weeks. I noticed a difference in the color of my teeth. I drink a lot of coffee and I feel like it couldn’t get the job done anymore. Once my teeth hit a certain level, it was almost like it didn’t whiten anymore. Unfortunately my teeth weren’t white.

Have been using this toothpaste for almost year now. I love the minty freshness. It's a great price and it's helped keep my teeth white and feeling clean. Whenever I go to the dentist he always compliments me on how good my teeth have been lookinf. I would definitely recommend this.

This is my favorite toothpaste and I’ve been using it for quite sometime. The taste is subtle and enjoyable as compared to other brands and obviously I use it everyday and it’s gentle on your gums. Highly recommend this because it also whitens your teeth gently.

Crest is the only toothpaste my family will use. Crest leaves my mouth feeling fresh and minty.  The moment I start brushing my mouth instantly feels clean.  The only con is I feel like for the price, I go through the toothpaste too fast.  The tube could be a little bigger. 

I’m giving this a 4 out of 5 because I think it’s a great everyday tooth paste in addition to any teeth whitening treatment. I currently use a teeth whitening foam in my Essex retainers at night & together has gotten some coffee stains out within 2 months. I would recommend that you use the 3D white toothbrush which compliments the paste. 

I always try and find a toothpaste that has whitening in it. Between my tea and cigarettes i need all the help i can get. This one is ok, but not my favorite. I didn’t really notice any difference in the coloring of my teeth after using for over a month. While im sure this works for aome, it just wasnt for me.
