I like these white strips. I use them about twice a week and there is a noticeable difference. The only negative thing I can say is tooth sensitivity, which is why I only use them twice a week instead of daily. Though, with every whitener you'll have tooth sensitivity.

I LOVE WHITESTRIPS. I don't use them often because they are expensive but they work and make your teeth look so good and clean! These are tried and true and never fail! You won't be disappointed I have them in my amazon cart currently!!! Love love love!

This teeth whitening kit does what it claims to do. It whitened my teeth quickly ( they were noticeably whiter after the 5th use) however after the first few uses I started experiencing great sensitivity and shooting sharp pains in my teeth. It got to a point where I had to stay up the night after using this out of pain. It's not worth the amount of pain it caused... I might purchase the sensitive one next time

I had a chance to try Crest 3D Whitestripsin the weeks approaching my step daughter's wedding. I absolutely loved the results! Not only were they easy to use, but the wedding photos turned out great with my gleaming white teeth! I had several people say how much younger I looked!

I purchased all of the Colgate Optic White kits (brush, paste, mouthwash, floss, whitening pen) and it did not work. I got tired of brushing my teeth 4 times a day just to have them "white" for that day because if i didn't brush my teeth the next day, they would turn yellow again and it would be really hard to turn them white the next day. I even used other stuff like baken soda with lemond and some peroxide. I found that Colgate and Arm & Hammer didnt work for me because Arm & Hammer has a really bad taste and it has too much baken soda that it irritates my teeth. I wanted to try something new and i bought the Crest 3D White and it was the best thing! It has a really great minty taste and if i dont brush my teeth for 2 days it washes all the dirt away it is really cool and i dont even have to use the lemonds with baking soda and strawberries and i dont even have to put mouthwash sometimes because the minty taste is so good that it stays there

The package claims that you can see visible whitening after only 3 days. This claim is true. I've never whitened my teeth before but they weren't too yellow to begin with and I noticed the difference after 3 days exactly. However, I also have sensitive teeth and by the third day, the strips had increased their sensitivity. The instructions say that if your teeth are sensitive, start using the strips every other day (instead of every day), so that's what I did. The sensitivity stopped immediately after skipping a day. I used the rest of the package in a similar manner: using the strips every other day, sometimes using them two days in a row. The whitening continued just fine using this method. My teeth are extremely clean looking now, but not that fluorescent look some people get with over-whitening. They just look pretty and clean. A few notes on usage. The strips are easy to apply, especially if you follow the instructions and put the bottom one on first. I definitely recommend, as the package says, to use them BEFORE you brush your teeth. The instructions say it will reduce tooth sensitivity but there's also another benefit: if you use them daily before you brush your teeth, you won't forget to do it AND you can brush off the gooey stuff that the strips leave behind on your teeth. Also, the strips are EXTREMELY sticky. They won't come off accidentally; they stay on securely. They are comfortable to wear. When you pull them off, make sure your fingers are dry so you can get a good grip to pull off the strip.

These are the only teeth whitening strips I have ever used which is why I am rating it a 4/5 because I don't have much to compare it to. However, I am super impressed with how white my teeth look when I use these and the only complaint I have is that sometimes the strips with make my teeth a bit sensitive. Even though these are kind of pricey they are totally worth the money and I love them!

I love these whitening strips! They work very good! I use them everyday! They are a bit pricey but In my opinion they are worth every penny! The pros are they leave your teeth so white and it last for a while. The only cons I have is that if you have sensitive teeth it can make them more sensitive the first couple of times using them.

Work very well as directed, the strips are very comfortable and low profile. I've tried store brand strips and these are worth the extra. I always brush with an enamel strengthening toothpaste for a few brushes after and it helps eliminate sensitivity

I love your 3DWhite whitestrips,I try to use them every 4 months,they do get pricey but well worth the effects. People always comment on how white my teeth are As I am getting older,this plus in my life is rewarding..all the negitives and seeing yourself aging to have a product that lifts your smile is great!
