It whitens, but I'm fully aware of whitening teeth at home isn't super safe. I use every so often and it works, but I try not use it too often. The price is kind of up there, but for quick fixes it's ok.

These strips are an all time favorite! They really do the job. Not only do you get super white, glowing teeth, but it lasts for months! These strips remove all coffee stains for those who drink a lot of coffee!

They are very efficient and effective. I use them at night. They don't make my teeth sensitive. They work as long as you stick to a schedule when using them.

These are my go to whitening strips! Even though they're on the pricier side, they really help remove the coffee stains from my teeth and are really easy to use. These are the only strips I use and I would buy them again.

I like these but they give me a lot of sensitivity which I don't like. I follow up with Sensodyne which seems to help enough but I wish they would put some helpful ingredients in there so I didn't have to use a whole other product.

Although these strips are a bit pricey, they get the job done just how they claim to. They really work and they whiten even tough stains as well! Get professional type quality for a lot less of the cost.

Crest has been our brand for years. This has a minty taste and I like the way it cleans my teeth. It doesn't get them white like using strips or treatment but I can see a slight difference.

Love the convenience of having these in my home. I use them sporadically to keep my teeth looking pearly white all the time. Easy to use! And bright white!

Professional quality that one can get at home, Crest 3D White Professional Effects Whitestrips are the most effective and advanced whitening strips on the market. No special glasses needed to see the dazzling white special effects!

Love love love. In just a few uses it lifted my teeth a different shade. The taste is manageable and you don't need to keep them on for that long. Definitely met expectations however they are pretty pricey
