When I tried Crest Whitening it did wonders for my teeth. And I didn't believe that it would because I've used other products that said that they would do the same thing and they didn't. So I was quite skeptical. But, this one is one of the best I've ever used in my life. It was very sensitive to my teeth and the packaging was alluring. And it definitely did whiten my teeth so much so that I recommended it to everyone I knew that needed a whitener in their life. Crest is one of the best toothpaste I know and their whitening strips are also one of the best.

These strips have been around for years and are a new feel way of whitening your teeth at home. My teeth to get somewhat sensitive after using them. However, I do just naturally have sensitive teeth to begin with. You really can't go wrong with these.

Very good product if you are will to spend the money. Definitely does a great job whitening if you use as directed. But for the price I would rather just buy hydrogen peroxide to white my teeth with since it's literally the same thing but in liquid form and less than a dollar at most stores. Strips also make my teeth super sensitive.

Love these whitestrips I have been using these white strips for many years. I just love how they make my teeth whiter and brighter. I get so many compliments on my teeth, even my dentist exclaims how white they are and ask what I use. They even laugh when they have to move the light above me because they are so bright. I would, and have recommended these white strips to my family and friends. I use the professional effects.Less

Finally!!!! A teeth whitening strip that doesn't make my teeth ache in pain. I love these strips, they give quick result and they are easy to use! My favorite thing about this is that I can whiten my teeth pain free + there is no icky after taste from the whitening strips. 100% these are one!

I used to use these regularly, I definitely notice my teeth get whiter but it makes my teeth super sensitive! I now only use them on special occasions and have found that cutting the strip in half helps! Since the strip is smaller it doesn't touch my gums and doesn't leave my teeth feeling sensitive! Plus you get more uses!

Never used any strips or any whitening agents except normal whitening toothpaste on occasions. Was skeptical and I intentionally took photo before and after 14 days as seen below I still have 6 days to go before my pack is finished. I work abroad and when I shared the photo with my wife she said photo shopped? I said it is not!!! I always thought my teeth was fairly white and in good condition, until I realized how bad it was looking at this photo's I am quite embarrassed to be honest. Needless to say I will stock up on this product, never want to be in the “before” position again urggggg. I do however wish they have included shade strip, then I could determine how many shades I am whiter seems more than 34 as stated on the package. Still embarrassed though that I waited this long. Highly recommended and can't wait to take some for my family to use. Almost forgot same spot photo taken, considering light and no filters, no editing, I just cropped to hide my face and give you true sense comparison. I am truly embarrassed! Ok just loaded photo's, I know it is till not perfect and I still gave 6 days to go! Maybe Crest will be raising their prices after this review, I hope not I am in the US in mid June only LOL

It's a bit on the expensive side but if you want noticable results I would highly recommend this product. The kit includes everything you need and takes the guess work out using the product. It's no replacement for professional teeth whitening but it works great.

Of course crest whitening strips work. The stronger ones, the better. I knocked off a star because these caused sensitivity issues for me. I had to switch to gentle routine version that are only worn 5 min. I tried wearing these for five min but sensitive issues persisted. If you don't have that problem then def try these for bright white teeth. Look for coupons.

The first couple of uses were honestly really rough, I was really embarrassed and bothered by the white spots that were appearing after the first couple of uses. I would have stopped immediately if the label did not warn me about the white spots that may occur.However the teeth could be sore from this teeth strips. Try not to eat anything sensor to your teeth for a shot amount of period
