What could be easier that Peel, Apply, Reveal your whiter teeth? Very easy to use, the top strip goes over the top teeth, bottom strip on the bottom teeth. Whitening  gel on the teeth and make sure you position up to the gum line and fold the flexible strip to the back side of your teeth. Easy as can be! Thirty minutes wear time is all it takes and you have beautiful white teeth. The claim is these whiten 25X more than whitening toothpaste, I don't know if that's true or not but I am a coffee drinker so I use these once a month or so and love the results.

These definitely work great! They whiten quickly and easily. I used to use these all the time with no issues, but as I have grown older, it seems my teeth have gotten more sensitive & when I try to use them now it makes my teeth hurt. I just have been using the toothpaste alone instead.

I loooooveeeeeeeee these so much! They work and the one that comes with the little stick to boost whitening is awesome (I’m not sure if this is the specific one) but it definitely does weaken your enamel, i can feel it when i drink which is why i stopped using it !

I loved these whitening strips! My teeth were pretty yellow before, but now they’re super white! The change was immediate and very noticeable. Only problem is it breaks down your enamel, which can lead to toothaches, but unfortunately, that’s what whitening your teeth is.

Absolutely wonderful! These whitening strips whiten teeth instantly. Although using them day after day can lead to teeth sensitivity, they are still my go-to! I would suggest not using them daily & spreading out the usage. The effects are long lasting!

I've used this product in the past and was very happy with the results. Have you made changes to the product? I'm on my 2nd box and it just doesn't seem to work as well as it did a year ago. At first I could tell a difference; but I don't have the "whitening" I had from the same product a year ago.

A MUST for white teeth. I would definitely advise caution though because these do make my teeth sensitive and I don’t even have sensitive teeth. That being said, I’d you do have sensitive teeth, I reckon this would make it much worse. These do work like an absolute charm though. Haven’t found anything at-home that’s comparable.

I’ve been using these for years but les and less frequently because of how sensitive my teeth have become to them. They definitely work which is why I love them. I recently was told by a dentist that if I use sensodyne for a few weeks before using the strips it should help with the sensitivity so I’m planning to try this soon!

My teeth are rather normal off color and not a whole lot of nasty. I don't drink coffee, smoke or drink red wine. I used the Crest mouthwash and Crest toothpaste while I used the Vivid strips, which didn't work. Then, I used Professional Effects and it didn't do anything either. A friend gave me an extra ten packs of ProEffect strips also. So, I was more despondent than anything.

I was very disappointed as I have used crest strips many times over the past 6-7 years and now am wondering if they have changed the formula as I did not get the results that I have had in the past. I am not a smoker or coffee drinker and use Crest 3D mouthwash, tooth past and Brilliance booster two-three times daily so the whole system should work together. These are the most expensive strips on the market and I will not buy them again.
