They definitely work! I have pretty sensitive teeth so I don't whiten often. But when I do, these are my go to. They don't leave my teeth achy like other whitening treatments do.

This causes visible results when i use these. They are a little expensive, but useful. I only use them every so often. The taste has definitely improved over time and the strips are now sticking to my teeth.

Wow! This product began taking the stains and discoloration away almost over night! I have been using these strips for almost 2 years periodically and never have been disappointed!

Works soo well for a drugstore product! My dental hygienist recommended these instead of spending hundreds on professional whitening. They work!!! They work fast too! I recommend to all my friends when they're looking for a cheap and easy option

These teeth whitening strips are my favorite! Because of my love for coffee and tea, my teeth are exposed to lots of caffiene and turns yellow easily. However, these strips have helped keep my teeth pearly white! :)

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.

I didn't really have a great experience with these. They tasted really bad and didn't show any effectiveness on my teeth. I honestly think the off brand did better for me. Won't by again.

Quick easy way to freshen up the pearly whites before an event or night out. Personally, I prefer this brand over others because it's easy to apply and wear without the mess of gels.

I love these! They work wonders, I used them for a week straight every night and my teeth are super white now! Just be careful because I don't know how sensitive teeth will react to this product... Other than that, they're amazing and easy to use!

These strips work!! I'm very happy with the results. They stay put. I can drink water while wearing them if I want to and I don't talk funny while wearing them either.
