I have lightly pale yellow stained teeth from drinking soda as kid as well as braces. I have tried whitestrips in the past and got frustrated that they didn't stay on your teeth. I am 1 week into the treatment and while I cant say I have had amazing results I feel like I can see a small difference. They have greatly improved the strips so they stick well on your teeth. I am hoping once I am done with the whole package I will have bright white teeth. Fingers crossed!

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.

I had a coupon, I figured what the heck. I am sitting here with my teeth clenched together for the last 20 minutes now because almost as soon as I put the strips on, the slid back off. They do not stick well at all. Because i spent the money, I am going to try and complete the whole ten day regime. Given this poor initial performance, I honestly do not expect any worthwhile results.

I have tried other whitening methods and these ones are the best by far. I had the same results with dentist professional whitening that was very expensive. This are easy to apply, they stay in place and i dont get the pain like others! I never finish all the stips in the box, because they work pretty fast and i get the desired results immediately Yes, I would recommend this product to everyone.

I love professional effects, been using for 4 years, use less and less every along with the mouthwash and paste . Introduced all to my grand daughter 2 years ago. She lives in the country and has well water. That alone tends to yellow the teeth. She now has the smile of an angel and the personality to match. Thanks for making such a great product. The whiter teeth gave her more confidence in her appearance and now at the tender age of 15 1/2 she is more beautiful and confident than she has ever been.

I love how the Professional Effects White strips adhere to my teeth for the whole 30 minutes. This allows me to continue multi-tasking, while easily whitening my teeth. I also love how I notice immediate whitening effects after using the products only a couple of times. I would totally recommend Crest 3D Whitestrips and plan on purchasing these for my sister for Xmas. #3DWhite

[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.

I absolutely love these whitestrips - they are the closest thing to a dentist's whitening treatment. They stuck well to my teeth, and I really did notice results in 1 day when I used them along with the toothpaste and rinse. I recommend that anyone who wants white teeth to go for these. They may be a little more expensive, but they are totally worth it! You'll actually get the results that you were looking for. I really can't believe how white my teeth are, I am so happy I tried this product!! I will definitely be buying this again (that is when it's ok for me to whiten again :) ).

I used the kit, and had no difference occur. I was very surprised because many years ago I used one of the first kits in this product line, and noticed results. I don't smoke, or drink coffee. Only drink red wines or tea occasionally. Adhered to teeth well, and stayed put. These strips are easy, and convenient to use.
