Love these white strips! I use a set only every few years and I feel like they really give me the results I want. Only 30 min a day for white teeth! Worth the price for how long the whitening lasts.

litlle painful after using for a period of time. it was good at first but then it became hard. if you have sensitive teeth dont use it because of the pain.

The only teeth whitening system I've used that works. I've done zoom before and it left my teeth splotchy and really sore, but crest isn't super damaging to my teeth but visibly whitens

This product is quick and easy to use. Ill stick the strips on and then hop in the shower and do my makeup and then take them off before leaving the house. Ive only used crest for whitening and no other brands

Gives you white teeth in just a few days. I love the clean white fresh look I get after these strips. Tea/Coffee and any other staining food I eat will not ruin my smile, thanks to Crest 3D Whitestrips Proff Effects.

This most definitely works you just have to be continuous. I used it every other day. It does cause some teeth sensitivity. I most definitely meet my expectations. I will continue to use this.

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.

My favorite crest product as well at the 3D mouth wash. It makes me teeth glow white and if you are looking for a whitening product this is what you should use!

Easy to use but amazing effect. Don't even notice it's on your teeth. Really a good product. I have used this for the last five to six years and I wouldn't recommend any other type.

Crest has the best white strips!!!!! They work so well and fast I love them and can tell a huge difference even after just 2-3 applications. They stick really well and are easy to apply and take off.
