My teeth are whiter but what a drag literally with the lower strip. It slides all over the place and does not seem to have worked as well. My teeth are a little sensitive but it helps with Sensodyne toothpaste.

Although this product allowed my teeth to be very, very white, after about two weeks later, my teeth started losing its whiteness and changed back to its original color that I started out with. This product isn't worth the price. I would recommend this product to people with too much unnecessary cash that needs to be spent on somewhere, someplace on something. Probably regular usage and restocking can maintain teeth's whiteness, but not for one-time use (the whole box, I mean.)

I've been using these strips twice a day, as directed, for about a week now. My teeth do look whiter already. The product does make your teeth hurt- like that feeling you get on your finger when you get peroxide on the tip of it and it gets white? Well, that's what it feels like on your teeth but not when you're actually using the product but randomly throughout the day- it doesn't hurt if you only use the strips once a day though. But I continue to use it twice a day. The taste isn't cotton candy but it's not as horrible some here are trying to make it out to be. The bottom strips are too short (that's why it's 4 instead of 5 stars) and they are more difficult to put on but drying your teeth first does help. Very little gum irritation for me. Don't put the strip on your gums; keep it just above the gum line. I'd definitely recommend it.

This product seemed to work moderately well, although I'm not sure my teeth look dramatically whiter (although maybe that's a good thing). I experienced mild tooth sensitivity; but it's tolerable and goes away after a little while. Notably, what I didnt expect is that my lips became extremely dry after initially using the strips (allergic reaction?). Thereafter, I put Vaseline on my lips BEFORE applying the strips to my teeth. This protected my lips and helped a little bit.

I used the strips at night before going to bed. My mom said that my teeth looked noticeably whiter. Even when I looked in the mirror I noticed they looked whiter.

Im 15, I already had pretty white teeth with a little yellow, but I wanted them to be even better when I got my braces off. These are fantastic! They do cause a little sensitivity, but I used Sensodyne. What I would do was brush very lightly with the Sensodyne right before I put the strips on. If you make your gums bleed or feel sore though, wait a day. I made the mistake of putting them right on after my gums bled a little from brushing too hard, and they were sore for like 3 days afterward. My dentist told me that as long as you brush lightly its fine.

I use these white strips about once a year. They do a nice job of whitening teeth and they can sometimes be found on sale. I have not had any problems with tooth sensitivity. The instructions say not to use the strips right after brushing the teeth but that is the only times of day that it is convenient for me to use them, also the only times I can remember to put them on. I have not had any problems with doing it this way. The only reason I didn't give 5 stars is because the strips can be a little difficult to apply until you get the hang of it. They also feel sort of strange and icky while stuck to the teeth. I would recommend this product. It's an effective alternative to pricey bleaching at the dentist's office.

I am really happy with how my teeth turned out, but their not as white as i expected. I had trouble with the lower strip sliding. You constantly have to fix the lower strip. And before I used them, people said that your teeth get super sensitive when after you wear them, but I didn't experience that.

I love this product. I did one packet for 2 weeks straight. Make sure you do it EVERY DAY AND TWICE A DAY, like it states. Your results are awesome. Don't overdo it, it can hurt your teeth in the long run. Definitely will buy it again...

I have not used other whitening products, so I cannot compare it to others, but these strips worked extremely well on my teeth. My teeth were very very sensitive after the initial use, and remained somewhat sensitive through the process, but I switched to Sensodyne as toothpaste, and that worked well for me. It might be a good idea to get another pack for a second application, if you want better results.
