Really whitens my teeth and it doesn't taste that bad. They aren't uncomfortable to use either but if your teeth are sensitive I would be careful because sometimes it can hurt

When I feel like my teeth that need a little extra love and are looking to doll I love using the crest 3-D white strips. They are a bit on the pricey side but they do work very effectively on whitening my teeth after just one use

I've had my teeth professionally whitened at the dentist and it was an uncomfortable process. I got the same results with Crest whitening strips. They are easy to put on and wear. Highly recommended.

This is the best thing if you want your teeth to become white. Make sure you follow the directions because this product can make your teeth hurt if you leave them on for too long. But overall I would say that this is a must have.

White strips do the job over time but they are frustrating to use and require you to basically only be whitening, because all I can focus on is the gelly strips on my teeth.

I only use this before special events but usually about 2 weeks before I will start this whitening treatment and I'm always super impressed by the results!

These strips are my favorite. I m 51 years old and these get my teeth as white as I want them. I will continue the use these. They are easy and the sensitivity is not bad.

I like using these to get my teeth white. I can't use them all the time because I have a few broken teeth and when I put these strips on, it makes my nerve endings hurt. I usually use it about twice a year. 

I loved these. They made my teeth whiter after just one use which was amazing because I needed them in a rush. However, I would've liked to know that if you have sensitive teeth they might make them sore.

While they obviously don't work as well as a professional teeth whitening, these are a good at home option. They don't irritate my teeth but I've heard from others that they can have that side effect.
