I grew up with not the best teeth cleaning standards. Resultantly, I have had stained teeth that I couldn't do much about. I have tried many whitening aids from gels and trays to whitening strips, whitening toothpastes, mouth rinses, etc. I tried the original crest whitestrips and was not impressed. I recently purchased Crest 3D White Professional Effects, and noticed a difference after the first strip was removed. At day 3, just as the box says, a definite difference was shown. Others have noticed as well. The first day I had slight sensitivity, but I have not had that problem since.

So about 4 years ago I got my braces taken off and was so happy to finally have straight teeth. But then I noticed that they weren't as white as before braces,so I decided to purchase the Crest 3D Professional Strips because I like the fact that I got so many in the pack. I used then for almost two weeks anf tapered off the rest. My teeth haven't been the same since..in the best possible way. Now I whiten my teeth every year even though I keep getting comments on how white my teeth are. I get so many nice words about my teeth is a big confidence booster. So here's why I love these whitening shtrips 1) no gross taste in your mouth 2) 30 minute wait time 3) my teeth aren't sensitive after using 5) whiten my teeth like a professional did it.

Although it states it will not work on porcelain crowns it actually did on mine! One of my front teeth is a porcelain crown and I got it before I became a heavy smoker and cola drinker. It yellowed along with the other teeth but somehow the strips brightened it back to its original color. I have had no gum irritation or tooth sensitivity so far. The strips are easy to use, come off easily and leave no residue. I saw results immediately and am now on my fourth day and the results continue to astound me. Great product!

[This review was collected as part of a promotion.] I’ve tried Crest whitening toothpaste and the original crest white strips previously and had good results but didn’t expect to have such great visibly noticeable results so soon after only using three of the white strips. I am a daily tea drinker and use turmeric white often in my food and drinks, so my teeth weren’t as white as they could be. I usually use a teeth whitener to upkeep my teeth but didn’t notice a huge difference in the color of my teeth. After 3 uses of these white strips for only 10 minutes per whitening session, my teeth weren’t drastically whiter. The only downside is I noticed my teeth became sensitive after the first use. I was afraid of tooth sensitivity so I lessened the recommended time of use and only put the white strips on for 10 minutes. I had to use Sensodyne toothpaste in combination with these white strips to prevent further tooth sensitivity, but they do work and made my teeth at least 3-4 shades whiter than before. I plan on using the rest of the white strips in the kit, but I wanted to spread them out further throughout the next few months to give my teeth a break from the sensitivity.

I have used every single Crest whitestrip available. I have used them for several years. I absolutely love the product and results. Everytime I go to the dentist(every 4-6 months for cleaning) my dentist and hygenist ask if I am using their whitening system. When I tell them no, I use the Crest whitestrips they are blown away. I am always getting compliments on my smile and how white my teeth are, Whenever I have a birthday or for Christmas, the only gift I ask for is Crest Whitestrips!! They are the bomb!!!!

I have used Premium Plus White Strips in the past and have had AMAZING results!!! I decided it was time to whiten again after almost 2 years and decided on the Pro Effects.In my honest opinion they are not what I expected. I do not smoke, drink coffee rarely, never drink red wine, soda once in a while...nothing consistent enough that would stain my teeth...so I did expect more from these strips. That being said maybe I bought a bad batch of strips?!? I do have faith in crest products, just not very happy with this particular product.

I've been using crest 3d whitening strips for over 3 years and I find myself always getting compliments on how white my teeth are. On a regular I would say I drink at least 4 cups of coffee A DAY, sometimes more -_- so this product definitely keeps my teeth from yellowing. Highly recommend crest 3d whitening strips!!

[This review was collected as part of a promotion.] I tried the Crest 3D Whitestrips for a week and while they did noticeably whiten my teeth, I did experience some tooth sensitivity along the way. The strips were easy to use, but I noticed a few spots where the whitening solution seemed more concentrated, which led to uneven results in certain areas. Some parts of my teeth are whiter than others, so it’s not a perfectly even transformation. They work, but I’d recommend being careful with placement and maybe using them every other day if you have sensitive teeth.

While I was going to the pharmacy .. the girl who worked there when I was talking to her I saw her tooth and I was impressed about them , I asked her about their whitening , she answered me saying I used the " crest 3D white whitestrips. so after one week I bought this product and it was really amazing , incredible results , and now I got a great smile . Thank you Crest .

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!
