My name is Jaclyn, I'm 24, I recently used the Crest 3D White Whitestrips Professional Effects and was simply blown away by the results. Let me first just say that I have been using Crest 3D Whitening Strips sporadically since 2007. I had a dull, yellow smile in high school, but after using the product for the first time, my confidence soared after people continuously complimented my smile. I simply love the product, and after my first use of the Crest Whitening Strips, I have never used another. My experience with the Professional Effects is simply my best yet. I have become a coffee drinker since starting my new career, and Crest Whiteing Strips provided me with my full, bright smile again with hardly any sensitivity. I am truly floored by this product's ability to continuously improve, and I thank you for my beautiful smile. To this day, it is usually the first compliment I recieve when meeting new people, and i truly have your Professional Effects strips and your 3D Whitening Toothpaste to thank for that. Thank you for giving me confidence to meet new people, and to share my smile with the world.

I am completely satisfied with Crest 3D White Whitestrips Professional Effects!!! I have been a loyal Crest customer and the whitestrips line has improved drastically since I first tried the product years ago. Older versions seemed to slip around in my mouth and were inconvenient. Thanks to the improved product design, the whitestrips adhere to my teeth and stay put for the duration of the whitening process. I would recommend this product to anyone that desires a whiter, more attractive smile! I will definitely be trying the other products in the whitening line.

[This review was collected as part of a promotion.] I love crest whitening strips I think these work amazing. Honestly I believe they work better than stated on the packaging and they only cause me sensitivity if I use them too frequently. I love that they don’t slide like they used to!

My teeth are rather normal off color and not a whole lot of nasty. I don't drink coffee, smoke or drink red wine. I used the Crest mouthwash and Crest toothpaste while I used the Vivid strips, which didn't work. Then, I used Professional Effects and it didn't do anything either. A friend gave me an extra ten packs of ProEffect strips also. So, I was more despondent than anything.

I haven't even used the whole box yet, and my teeth already look amazing! I had been putting off buying whitening strips because I thought they wouldn't work or would slip off my teeth and be useless, but I gave in and bought these because I heard from a friend that they worked. I could see a difference after just 2 uses, and the strips stay right in place! My teeth are more than noticeably whiter and my gums have evened out, making my teeth look bigger (which was much needed). I highly recommend this product to anyone. It has boosted my confidence level and I feel like I have a beautiful smile!

I loved these strips! I have extremely sensitive teeth, which is usually a result of irritated gums, and traditional strips are flimsy and don't stay on my teeth and I end up with whitening gel all over my gums. Not with these - they stayed put, didn't cause sensitivity, and really work!! I will absolutely buy these again.

[This review was collected as part of a promotion.] The application was super easy—they stuck well and didn’t slide around, even while I was multitasking. I kept them on for 30 minutes like the instructions said, and by the time I took them off, I could already see a subtle difference. After the second day, my teeth looked noticeably whiter and just cleaner overall, like I had just come from a dental cleaning. There was a tiny bit of sensitivity, but nothing unbearable. It’s such a quick fix when you want to boost your smile fast—definitely something I’ll keep on hand for special occasions or when I need a confidence pick-me-up.

I received a trial offer of Crest's 3D whitening toothpaste, mouth wash, and whitening strips, and honestly, my first thought was: sure, nice packaging/advertising on the products themselves, but will they actually work? I am a heavy coffee drinker (at least 7 cups a day). The difference before I brushed and after (first time using it) was astounding! I couldn't believe my eyes!! You can actually see the whitening stuff go to work! Then I tried the teeth whitening strips and that is where I really was amazed....It took months of stains off my teeth in one use!!!!

I saw a difference after 1 use. After using the whole box, my teeth are much whiter and prettier. I get my teeth cleaned twice a year, but I'm 49, and my teeth were looking dingy and yellowish. Now they are a lovely, natural white, not a weird, radiant, high-beam white. The strips are dry when you put them on, so they're easy to handle and place. I used them in the morning, when I was getting into the shower. That way, my teeth were clean from the night before, but not sensitive from being freshly brushed. When applying, I'd start from the center, poking the strip into the spaces between my teeth with my fingernail, so that the whole tooth was in contact with the strip. They didn't budge after pressing them in place.

This product has done wonders for my enamel shade. I am not a smoker and do not have reason for staining. My teeth are just not as white as I would like them to be. I was not expecting miracles, but I did improve a few shade to make my self confidence sky rocket :)
