My oldest daughter was getting married and I wanted to whiten my teeth. I got the 3D white strips and noticed a difference in color even after just the first treatment. They were very easy to use and stayed on well during the treatment. Would recommend them to everybody!

I started using Crest 3D White Whitestrips, twice a year, for the last three years. Every time I visit my dentist, he expressed his amazement at the whiteness of my teeth. I had to have a porcelain crown made for a molar that has caused me grief since I was 17 years old, and the dentist struggled to find a porcelain white enough to match the rest of my teeth! Of course he was eager to find out what I'd been doing to keep my teeth so sparkling white, and I was more than happy to tell him Crest 3D Whitestrips Pro Effect :)

This product is such a great & easy at home whitening kit. Great for people who want to enhance their smile & brighten the look to life superficial staining from foods & beverages consumed on a daily basis. It's easy to use when you have a busy schedule & don 't have 2 hours to spare at a dental office. I would highly recommend this product!

3D Whitestrips professional effects to your oral-care routine for: • Professional teeth whitening at home. • Results last up to a whole year. • Apply daily for 30 minutes. • Advanced Seal's technology, no-slip grip, stays put so you can talk and drink water while whitening your teeth. • 3D Whitestrips use the same enamel-safe teeth whitener that dentists use. 3D Whitestrips allow you to see results after 3 days, with full results in 20.

The whitestrips were sooo much better than the previous ones I've tried (and I've tried everything). I wasn't expecting much of a difference, but as soon as I put them on my teeth, they created a really tight seal and didn't budge while I wore them! I showered in them, read in them, and could have probably done just about every aside from eating in them. It took actual effort to get them off, unlike most strips that slide around...accidentally whitening my tongue and getting goop everywhere. I noticed a difference in just a couple days and enjoyed the fact that I only had to wear them once a day!

I ran into my eldest sister years ago smiling (she doesn't normally show her teeth) but as soon as she smiled at me I KNEW she had been to the dentist, but boy was I wrong! She had introduced me to crest 3d professional effects and since then I have been hooked!! I cannot believe that they actually work!! I drink a lot of coffee and was a smoker for years and I can use a strip a day for a couple of days and my teeth are pearly white!! Even just one strip makes a huge difference!

I gotta say, I was skeptical... I'd read all the reviews prior to purchasing and was still skeptical.... But I gotta tell you, I am so glad I tried these! I am a smoker and a coffee fanatic and was worried that they might not work for me - but these white strips work! I did experience some sensitivity, but I highly recommend this product! Don't think twice! If you're thinking about trying them, do it - you'll be so glad you did!

[This review was collected as part of a promotion.] Definitely seen a color difference on my teeth during the first week of use. I don’t like that I had to leave them on for an hour. Felt like it was too long, didn’t feel them on my teeth but I did feel sensitivity on my teeth after using them because I use sensitive toothpaste. Love how my teeth looked after using them. If you can stand the sensitivity I would definitely 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.

I had tried a different version of the Crest Whitestrips in the past but saw almost no results with them. Decided to give the Professional Effects a try and was very pleased with the results. My teeth are significantly whiter (since I had previously had bad luck with the strips I only did my top teeth at first and the difference was very noticeable after 6-8 days). The only downside for me of this product is that I did experience slight sensitivity on my top teeth and pretty significant sensitivity on my bottom teeth (in part due to previous dental work I'm sure).
