I've used these off and on for years and have been happy with the results every time. I get compliments on my white teeth and have never had to have them done professionally.

I had a stain from my braces and I was self conscious of it. I used the whitening strips to help even it out and I get compliments all the time on how white my teeth are. I don't even do it that consistently

I liked so much how it helped my teeth to be whither however it would be great they could improve the sensation after using it. I felt very sensitive for about 4 hours

The crest stripes are a little on the pricey side , but they have made such a huge difference in my teeth and make them probably 2 shades whiter ! I use these maybe twice a month and I am obsessed. I drink coffee and my teeth are still super white!

These are an excellent option for a quick fix. That being said they don't whiten your molar teeth. I prefer to use these when I'm busy and need a quick fix on the go.

these can be a little pricey but in my opinion they are definitely worth it, they do whiten my teeth without the extra work of having to do the whitening strips. but if you want better result's definitely do the whitening strips also!

Love this tooth paste. It has replaced whiten strips for me so I do not have to deal with sensitive teeth. You can see your teeth whiten after a few uses.

Love this product! Whitens teeth so fast I use them all the time and I swear by them, it is truly a great product. I will always continue to but them!

They were slimy and wouldn't stay in my teeth very well but it didn't stop em from doing there thing!! If they wasn't so expensive I'd still be using em!

Many love this product and while it does work and do it's purpose and effect I've had some negative experience with gum burning and stinging and cannot let it last the duration.
