Unfortunately these haven’t worked for me. I ate nothing but white food to make sure I didn’t do anything to hinder the whitening process. They worked great a few years ago, so maybe I got an old box (could not find any expiry date anywhere)

With whitening effects from the Professional system, I have much more confidence. I receive compliments on my smile every day. So easy to use and comfortable.

On my second order. I get lots of compliments on how bright my teeth are - even from my dentist. So easy to use. I put the strips on just before bedtime - watch a 30 minute program and remove! In addition I use Crest 3D White toothpaste daily.

May I know why there’s an uneven whitening after my first use of 3D professional effects white stripes? Should I continue or stop using the remaining white stripes? Hope to get your reply soon.

[This review was collected as part of a promotion.] Very effective. Great value. Comfortable when using. Doesn’t make my teeth sensitive. Packaging is a durable box. Definitely try this brand of whitening products

I am using CREST its very unambiguous product.I love it.its reduced yellowish color quickly not an week its done in few days.Thank you CREST Team members......TEETH+CREST=WHITENING TEETH+OTHERS(COSTLY)=YELLOw

These white strips work extremely well. I'm a coffee drinker and these strips do a wonderful job of removing stains and whitening my teeth. The whitening also lasts for a very long time. This product is definitely worth the money.

These are so easy to use and hassle-free, I much prefer using self adhesive strips than a mouth guard/tray system. Professional effects whitens my teeth really beautifully :).

I had put off my dental work and had family issues come up that made me totally forget to bleach to prepare for it. I bought these 5 days before and used them and can't believe how well they worked! And no sensitivity at all!

Use to maintain my pearly whites, and am constantly complimented by my dentist(s), as I prefer a natural tone of white, than pure white color. They ask if I brush my teeth often to maintain... Flattering for my dentist to not even be able to tell!
