I used to use the DIY teeth whitening tricks such as baking soda, peroxide, coconut oil and even the activated charcoal. I could barely notice a different and did no one seemed to notice. Withing 3 weeks of using my crest white strips I heard more than once that week how white my teeth looked. Using the strips doesn't cause a mess like my other efforts have caused. It's easy and effective. I love my 3D crest strips. They are worth every penny.

I have bought so many other brands of white strips and none of them seem to work for me till one of my friend said to try Crest White Strips because it worked for her. So I decided to buy them and it was well worth it. Easy to put on and only a few min. I wear it as I take the train in NYC on my way to work. Took less then a month and time flies when your not focusing on it. I have to say it was well worth it and worth every penny. Give it a try thats what I did and I never looked back at another brand of white strips.

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 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 been using these white strips for many years. I just love how they make my teeth whiter and brighter. I get so many compliments on my teeth, even my dentist exclaims how white they are and ask what I use. They even laugh when they have to move the light above me because they are so bright. I would, and have recommended these white strips to my family and friends. I use the professional effects.

Over the years I have tried countless whitening products, but was always left disappointed. I had always been a little skeptical about Crest Whitening Strips, kind of like one of those "too good to be true" kind of things. Until one evening when I thought I would just give the whitening thing one last try. After the first two nights I was astonished by the results. Not only did I notice the immense difference in my smile, so did my friends and colleagues. I have never felt more confident in my smile. I might even dare to say it is absolutely flawless. Crest Whitening Strips not only turned my average white teeth into an impeccable smile, but it also gave me the confidence to walk around everyday flaunt my smile. In my book, you can't put a price tag on feeling beautiful and confident. Even if you had to, I'd say these are a steal.

[This review was collected as part of a promotion.] I’ve been using Crest for years and absolutely love it! Using Crest 3D Whitestrips Professional Effects has become a part of my weekly routine and has made a huge difference in my smile and overall confidence. I recommend them to all of my friends!

Needless to say with no fanfare. Crest 3D White Whitestrips Professsional Effects are by far the most effective most whitening whitestrips on the market. They are easy to use, affordable and after you get through using them the compliments just keep coming in. People notice a difference right away. They will improve your self esteem and you will find that smile of yours again!

I read a lot of good reviews so I ordered the product. The shipping was great and they got here very fast but things were only downhill after that. For one, my teeth aren't very stained at all so I thought this would go great but I can only see improvement on like 2 or 3 of my teeth and even on those the results are bare minimal. The other big issue is you don't even get the full 48 strips or whatever it's supposed to be because half of the box doesn't even stick to your teeth for whatever reason. Very disappointed to say the least.

I truly love the whitening strips, they too off so many years of stains off my teeth, my teeth actually make me feel beautiful now as before they were yellow n made me feel so self conscious about them! Now I love my pics taken n love smiling my big beautiful white smile!!!! Thank You Crest
