Results beyond expectations!!

My 16 year old daughter wanted to whiten her teeth, and my dentist recommended Crest Whitestrips. I really wish I could post the "before, during and after" pictures we took. Amazing results, we can not believe the difference in just 7 days! I would definitely recommend trying these.

Makes teeth super sensitive, whitening doesn’t las

[This review was collected as part of a promotion.] I was really hopeful about these whitening strips, since my teeth are a little yellow from soda stains. These didn’t really do much for me at all, they whitened a little bit but within days they were back to how they were before, even when I only drank water. These made my teeth extremely sensitive for hours after only wearing for 15 minutes. I’m sure they would work better if I could use them more than once a week but the pain from the sensitivity is too much for me, especially since they haven’t worked too well for me. Hopefully this changes over time or maybe I should invest in sensitive toothpaste, but I’ve had a better whitening experience from a dollar tree whitening gel- no joke! This is not worth the money, they’re definitely overpriced. It comes with a lot of strips but it hurts so badly.

reply from Customer Care

We're sorry to hear that your teeth were left sensitive, and we hope you're feeling better, Zoey. Some users may be more prone to sensitivity than others, and, as with any teeth whitening product containing peroxide, sensitivity or soreness may temporarily develop when using Crest Whitestrips. There are steps you can take to reduce/eliminate this sensitivity, such as using a soft-bristled toothbrush and gentle toothpaste. It's okay to use Whitestrips over a longer period by waiting between applications or alternating between upper and lower strips. Doing so will cause whitening to take longer but will not cause a change in the overall whitening effect. If discomfort persists, we recommend you discontinue using the Whitestrips. So we can learn more and help further, please give us a call at (800) 395-8423, 9 am-6 pm EST, Monday-Friday.

I LOVE this product! The first time I used it, I didn’t notice a major difference; however, as I continued to use it I noticed my teeth got significantly whiter! I used the treatment several times in preparation for a photo session, and I was so happy with the results. If I leave it on for too long, my teeth can feel sensitive after use, but it’s never for long and the payoff is worth it!

I’m wearing these white strips as I write this review LOL. I think these white strips do a great job. They do make my teeth visibly whiter. Just make sure to not go over the time on the box you’re supposed to wear them or your teeth will be more sensitive the next day.

This is my yearly or bi-yearly go-to whitening product! They just work! I stopped using them for years because they do make my teeth a bit sensitive, but after trying several other products (that didn’t work at all) I came back to these! Even though I only use these about every other night (sometimes every third night) due to sensitivity issues, the end result is still always amazing! Interesting tip I learned from my dentist years ago: just because they recommend you take them off after 30 minutes, does not mean they stop working after 30 minutes! To get more bang for your buck, you can leave them on a bit longer to get more whitening. Due to my previously mentioned sensitivity, I just add on an extra 5-10 minutes each usage.

GET THESE. They are so so worth it for a whiter smile! My teeth have always struggled with brightness, but after using a box of these for just a few weeks every day, my smile is way different. This photo is completely unedited, and right after I finished a box

As a daily coffee drinker these are lifesavers!! I didn’t want to pay for an expensive whitening treatment and it wasn’t too much of a hassle to do this daily though the taste was really gross and it made my teeth extremely sensitive so I had to switch to sensodyne toothpaste to make things easier.

I bought these because so many people swear by them but unfortunately I didn’t get the results I was hoping for. They made my teeth incredibly sensitive so I couldn’t use them every day which may be the reason I didn’t get good results, but they were disappointing on the whitening aspect. I will be looking to try a different product next time.

HAPPY HAPPY HAPPY

After 4 long years with braces I finally took them off a couple months ago. I thought I was going to have that wow factor but I didn’t really get it. After applying the 14 day crest 3D white, people started to actually notice my braces were off! My 3D smile made me the happiest guy alive!

Crest 3D White Professional Effects Whitestrips Teeth Whitening Kit 20 Treatments Packaging May Vary A good tool for home teeth whitening. I used it for a month and my teeth became 1 tone lighter. I am pleased with the result. I think you should not use it often, but several times a year it would be good to maintain the effect #crest #whitening
