I have been a smoker for about ten years now, I do drink coffee and wine. Since I quit smoking I wanted to whiten my teeth. After the first time putting on the 3d white strips, I seen a huge difference! After I used the box I get so many positive remarks towards how white my teeth look. It is amazing!

I have tried other teeth whiting products and none can be compare to Crest 3d white. This product is awesome and I have refered it to all of my family members and friends. On the first day I used the strips,toothpaste and mouth wash people noticed how white my teeth were,I had great results on the first day of using Crest 3d white. People were telling me how bright and white my teeth were. I now have a new smile thanks crest 3D white.

I have used 2 boxes of the Professional Result Strips bu Crest and I am impressed. My teeth wet from c-1 shade to A-1 shade according to my dentist. I am using them now as maintenance to keep my teeth as white as I can get. I just turned65 yrs old and have never smoked, but I do like tea and coffee, so I do need the strips to keep them as white as can be. Im about to buy my 3rd box.

[This review was collected as part of a promotion.] Dentist recommended for whitening! Love the crest brand, can cause sensitivity* but that’s any major whitening - ease up usage / use less often if you experience sensitivity! Works very fast, couple days and you can notice a difference! Combined with toothpaste, mouthwash and the strips your teeth will be shining!

[This review was collected as part of a promotion.] Have been using this brand for years. I like the way they worked after just one use, I noticed that my teeth was way whiter than they were before treatment. Easy to apply and remove. Overall, great product, good price and nice packaging.

The package claims that you can see visible whitening after only 3 days. This claim is true. I've never whitened my teeth before but they weren't too yellow to begin with and I noticed the difference after 3 days exactly. However, I also have sensitive teeth and by the third day, the strips had increased their sensitivity. The instructions say that if your teeth are sensitive, start using the strips every other day (instead of every day), so that's what I did. The sensitivity stopped immediately after skipping a day. I used the rest of the package in a similar manner: using the strips every other day, sometimes using them two days in a row. The whitening continued just fine using this method. My teeth are extremely clean looking now, but not that fluorescent look some people get with over-whitening. They just look pretty and clean. A few notes on usage. The strips are easy to apply, especially if you follow the instructions and put the bottom one on first. I definitely recommend, as the package says, to use them BEFORE you brush your teeth. The instructions say it will reduce tooth sensitivity but there's also another benefit: if you use them daily before you brush your teeth, you won't forget to do it AND you can brush off the gooey stuff that the strips leave behind on your teeth. Also, the strips are EXTREMELY sticky. They won't come off accidentally; they stay on securely. They are comfortable to wear. When you pull them off, make sure your fingers are dry so you can get a good grip to pull off the strip.

I've been wearing these consistently for just a short while and am already starting to see results! I feel so much more confident going out and showing off my smile. They also stay on really easily as I go about my day to day activities which I love! Very happy with this purchase.

Professional Effects are by far the best whitestrips yet, I saw results with in the first few days and the best self-esteem boosting compliments I have ever gotten on my smile! I finally feel good about my smile! Definitely will be using this product over and over again

[This review was collected as part of a promotion.] Starting off strong with a simple yet attractive package that is easy to open! The strips are super easy to remove from packaging and apply to your teeth. Directions are simple and the results are amazing. You wear these for 45 minutes at a time and after just the first use, I definitely noticed improvement in whitening on my teeth! happy to say that I haven’t noticed any tooth sensitivity so far after 3 uses now! The strips stay stuck to your teeth during the full 45 minutes, which is awesome because there has been other ones that stay very slippery and tend to slide off

I recently had the fortune of sampling Crest's 3D White Strips and I am SOLD! They have done away with the messy residue! The strips are easy to apply and stay on without moving or becoming uncomfortable! My teeth are noticeably whiter! The new white strips are easy to apply, comfortable to wear, and leave no mess or bad taste in your mouth. I have already recommended them to friends and family and will definitely be a repeat buyer!
