Crest is the only brand of whitening strips I will use. Work great and can really notice a difference even after a few days of using! I drink coffee everyday and these really help get away those stains on my teeth

You will see a difference by using it 3 times. Each time you'll see a slight difference. They don't move around in the mouth so they will feel secure.

Didn't have noticeable results the first two times. Felt like these strips irritated my gums and teeth too much for it to be a product I'd continue using.

Crest is my go to teeth whitening system. I use them once a year. They are true to their promise- they whiten you're teeth quickly! Sometimes my teeth are a little sensitive after whitening but that is normal. Will use again and again.

These are my go-to whitening strips. I only have to use them once and then I can go several weeks/months without using them again. I don't like how they make my teeth sensitive the next day or two after using them though.

These are my go to for teeth whitening! Not harsh on your teeth and you see a difference almost immediately! I highly recommend this product and am always satisfied I have been using them for years !

VERY EXPENSIVE. But my boyfriends had extras and let me try them. I'm absolutely in love. It's just very hard to keep my teeth white, so this helps a lot

It is amazing. I used this like a week before my wedding, and everybody asked how I did it!! Lol in my wedding pictures my teeth are really white. I'd highly recommend this to everyone who is in need of teeth whitening process.

These whitening strips honestly worked over night. I was amazed by the quick results but you definitely have to keep the use up for them to truly stay and work. Overall an amazing product and would recommend to most.

This teeth whitening kit actually works! I use it once a year and it really whitens my teeth. I've used the glamorous one and the express white one but I like the professional effects more.
