These are the best whitening strips I have ever tried. The make my teeth look so bright and white and takes away any visible staining. They also do not make your teeth sensitive which is really the best part. They also will not slip or fall off during your time wearing them.

I have lightly pale yellow stained teeth from drinking soda as kid as well as braces. I have tried whitestrips in the past and got frustrated that they didn't stay on your teeth. I am 1 week into the treatment and while I cant say I have had amazing results I feel like I can see a small difference. They have greatly improved the strips so they stick well on your teeth. I am hoping once I am done with the whole package I will have bright white teeth. Fingers crossed!

I was very nervous at first, however, I jumped the gun and purchased the professional effects. Right now I have used 16 out of the 20 strips and I am so happy with the results. I used to have really yellow teeth and the treatment so far has lightened up my teeth at least 3 to 4 shades. It is very much noticeable to the point where I may not even need the extra 4 strips. The only side effect (as expected) is the teeth sensitivity (though no gum issues for me), which lasts about 3-4 hours post treatment and goes away after that. I rarely ever post reviews but I am very pleased with this product that I felt compelled to do so. Will definitely repurchase in the next few years.

I have tried other whitening treatments that did not work at all, but Crest whitening strips absolutly whitened my teeth in only 7 days. The intructions said to use it for 20 days but I stopped after 9 days since my teeth were already so white. I will use it again in a few months to keep them white. Very happy with results.By the way I am 68 years old

I think this is the kit I use. I typically use these right before a big event so not necessarily they’re “intended continuous use” that is how you’re going to get really noticeable results. But it definitely takes the edge off and I have gotten compliments on the whiteness of my teeth.

I got a 2 pack of 40 whitening strips. I used to use them about everyday for 30 minutes, but then forgot about it and got busy. When I was doing it everyday, I could see progress with my teeth, but then it went away when I stopped being in the routine of doing it everyday.

These are of the most popular whitening strips. Professional whitening can be expensive and such a drag. This is more affordable, keeps your teeth bright and white, and can be found anywhere. I keep mine on for an hour. If you have sensitive teeth like me it does make your teeth more sensitive- but I don’t mind.

I use this product to take away all of the stains from drinking so much tea lol. While they do work, they do take a little while and it does dry your mouth a little. Regardless, I still recommend this product to those that are looking for results that show.

As a dentist I’ve been using these strips for years to brighten my smile and remove surface staining. I use it twice a week for thirty minutes and I find that I have minimal/negligible sensitivity that is common with tooth whitening products. The strips are easy to use adhesives that you can just stick on to your teeth. Love them!

[This review was collected as part of a promotion.] The Crest whitetening strips are a very easy to use product to create a brighter smile. They come with a very sticky adhesive that will firmly stay on your teeth for the 45 minute duration. After the first use you can already see a benefit. The only thing is that my teeth are quite sensitive, so I cannot use this product everyday.
