I used the product 3D Crest Whitening Stripes a few months ago so I could have the whitest smile at prom. Within a week or two, I was more than happy with the results! All my friends were complimenting how white my teeth were and it gave me the biggest confidence boost ever. I've always wanted a beautiful white smile! To keep up with the wonderful whiteness, I use 3D Crest Whitening Toothpaste that tastes better than toothpaste should taste. It's honestly the best product I've ever used to keep my teeth clean and white. I plan on using the whitening stripes again this winter because I just LOVE having a perfect white smile! It's fast, easy to use, and 100% the best decision I've ever made.

I absolutely hate the taste of these. They conform to your teeth really nice and don't move, but they're hard to peel off sometimes and my teeth are EXTREMELY sensitive after using. I can probably manage one a week so I tapered off using them, my teeth may not be able to handle it. Do a test run!

Why is it that every other one I use has so much adhesive on it, that it is bonded to the clear plastic tray. In an attempt to remove it causes the product to distort and lacerate to the point it is too deformed to use. Considering the price of the product, one would expect better QC of the application method.

I love the old Crest Whitening Strips, but these new ones are terrible. They don't hold, I have to keep checking and making sure the strips are on my teeth. I didn't have to do that with the old ones. You guys are losing quality fast! I'd say save your money for a whitening treatment. ESPECIALLY if they're going to keep producing these low quality strips.

I had been a smoker for 15 years and I don't smile much because I have yellow teeth.I have used "strips" before.I dont remember brand but they didn't work which turned me off of strips. I set a goal to have white teeth for my wedding in November and I had decided to get my teeth professionally done,until I came across these strips. Money back claim on the box was reasonable if unsatisfied. So, I purchased a box. After the 5th use of these strips, I am completely satisfied with the results thus far. My teeth are turning white! I will use these again and I recommend these strips to others. I would like to suggest to Crest to make the strip for the bottom row longer.

I always get compliments everytime about how white my teeth are. People also always ask me how I got them so white and I always tell them that I use Crest Whitestrips. You have no idea how many customers I have brought to Crest Whitestrips. I feel like I should be brand ambassador. I've been using these since 2011, after I got my braces off. I have tried many others, but I don't get the same results. The whitestrips whiten within 3 uses and all of the different versions work. The only problem I have with these are how they cause teeth sensitivity.

For an at home whitening product this is one of the best. I try to whiten once or twice a year and this is my go to. I see real results every time I use these. The only thing is my teeth become very sensitive after use but after using tooth paste with sensitivity components it helps and goes away. Worth it and would definitely buy again.

My favorite teeth whitening product for my sensitive teeth - seems to effectively reduce coffee & tea discoloration without pain or too much effort. I use daily for about three weeks in a row anytime I notice that my smile isn't as bright as i would like !

I've used these for almost 8 years now. I get a lot of comments about how white my teeth are. I use maybe once a month. My teeth became more sensitive within the last year so I don't wear the full 30 minute. Wish I could find something that works just as well for sensitive teeth.

The only whitening strips that I've ever used that I notice a difference as soon as I take them off. My teeth are really sensitive and they definitely make mine hurt but beauty is pain baby (ps this is completely UNEDITED) yeah, they really that white lol colored contacts by qosmeticabeauty on insta!
