I drink A LOT of coffee, and we all now how dingy that can make your teeth work. Most of the time, products like this taste horrible, but I don't mind the taste of this. I get professional dentist results, but for way cheaper!

amazing product. this whitens my teeth like no other! I didn't have very yellow teeth to begin with but this took away all of the yellow I did have. I use them about twice a year just to keep up! I am very satisfied

I have noticed a difference in my teeth when I've used these in the past. I'd say the effect lasts about 6 months. They can be a little pricey, and product form my dentist works better.

I've used these off and on for 5 years. They're my go to. They seem pricey, but you can see the effects after just one to two uses. And they stay white! Would recommend for anyone. Warning: your teeth will be sensitive

Although they are a little pricey. They are definitely worth the money. I notice a huge difference in my teeth when I use these weekly. I do notice a bit sensitivity, but nothing too unbearable.

I love the white strips I used to use these all the time but I need to start using them again. Just be sure to have toothpaste for sensitivity. Other than that they did the job!

[This review was collected as part of a promotion.] Absolutely love these white strips! I immediately notice a big difference just after one singular use. I have sensitive gums and they do not seem to irritate me.

These whitening strips are a must have. They are worth your money. I saw results after just one week of using them. They are pricey, but I was not at all disappointed with them.

I love this product! I use the strips about twice a month to maintain a sparkling white smile. Though other products can create tooth sensitivity, I find the crest brand creates minimal sensitivity with maximum whitening!

I was kinda disappointed with how these turned out. I used them everyday for about two weeks. They didn't really whiten my teeth, but instead made them look splotchy.
