These strips are amazing! I didn't think they work work for such a great price but they did and I love them! I really want some more! I hope I win so I can!:)

These work really well. Definitely whiten my teeth. Super easy to apply and only need to leave on for 30 min. I use these every so often to keep my teeth white.

i was disappointed with this product. it was not effective. my teeth were  very sensitive to hot and cold from this product. i would not repurchase this item. i love crest company but it was also expensive and i felt i wasted my money.

I've used crest white strips since high school and they really work for me. I do a box probably once a year. They can cause some sensitivity but for me its mild and doable. Don't spend money on more expensive treatments, these will do the trick.

Very effective white strips. I'm guessing they aren't great for the enamel on your teeth because my teeth feel extremely sensitive after using. However if you keep up use of these they make a huge impact in the whiteness of your teeth

Very pleased with this brand and product. Keeps my teeth free of stains and yellowing, and is quick and easy to use on your own in the comfort of your home. I use it maybe twice a week and notice a huge difference.

I used this product a few times and although it did help whiten my teeth some I felt that it took way to long to notice a difference. This product also was harsh on my gums, it burnt areas that the product touched.

I am a dental hygienist and a lot of my patients ask me about whitening. I always recommend Crest 3D whitestrips for a great at home whitening. A lot of my patients had great results with it and so have I.

These work and are actually better for your teeth than whitening toothpaste. This does as promised and shows results within 3-4 days. I liked it but do not use too frequently as it causes tooth sensitivity.

They are good but my dentist said it's not good for the enamel or your teeth if you overdo it. So I limit it to once every 1-2 months. If you have sensitive teeth, your teeth will feel sore afterward.
