These definitely get the job done and keep your teeth looking white. My only issue is that I have calcium deposits in some of my teeth and this enhanced those which didn’t look great. The taste is also not ideal but that’s with any teeth whitener I think.

These strips definitely work wonders! I saw results in a matter of days. I drink coffee every day & they definitely cut through the stains on my teeth. You may feel some sensitivity and in that case I would recommend only using them one a day or every two days!

I use these every few weeks just once and it is amazing. I use it for the boost when my whitening toothpaste just it’s t fully cutting it or a day before an event. My teeth do get sensitive so I use an enamel building toothpaste to combat that. Highly recommend

I have received my package. I’m at my third treatment so far no results. However I’m very confident it’s too early to have noticiable results as my teeth are not extremely stained. But looking forward to whiter teeth after my active braces treatment. The only confusion I have is that I have just noticed than in this website the suggested time per treatment is 30 min. However in the box says 45 minutes. May I please get assistance on how many minutes should I leave the strips on.

The crest 3 d whitening strips worked well for me! I’ve only bought this product once or twice due to the price! The product was easy to use and made my teeth white In minutes! I would recommend this and I will be buying 3 d whitening strips again in the future.

Yes these work ! I was wowed I’ve been using them for a few years now and I rarely do it anymore but my teeth are pearly white , it will probably sensitive on your teeth at first but it’s well worth it trust me look at my Snow White teeth . Thank you Crest

White strips have come a long way - these are not gooey and messy like previous generations. These stick and stay on contact (so be sure to line them up correctly before pressing down!), and are really comfortable to wear. I don’t have random white blotches like other brands, but I still have some sensitivity for about 24 hours after use. I use these about once a week to every other week for whitening maintenance.

I saw a Huge difference in the color of my teeth. These shirts in my teeth so so white. They did however make them feel a bit sensitive but this has been a problem with any sort of whitening strips I’ve used. They did not damage my name although according to my dentist and I would use them again just have to space out when I use them

Noticeably whiter teeth after 30 days! It is kind of weird to feel the strips on, but after getting my results, it was totally worth it! If I had more money, I'd buy it again! Does not cause any new sensitivity problems and it does work well! This is what was recommended by my dentist friends!

Crest 3D white strips are so easy to use and you can see mold results with your first treatment. The strips don’t slide around, but sometimes you might get a weird taste in your mouth from the strips. Overall, I love crest white strips and will continue to use and purchase them
