Definitely whitens teeth, but makes my gums and teeth sensitive, which makes me not want to always use them.

Hurt my teeth. I stopped using these after a while because I felt like they were damaging. Definitely worked though. My teeth were noticeable whiter.

my teeth were visibly whiter after only a short amount of time. i used these before prom and had great results.

Noticeable effects after a period of time. Just difficult to keep on teeth especially if you have smaller teeth like me

I love these strips! They are quite pricey and I wish they were less expensive but in the end I want the results so I spend the money.

I have used this product for over 5 years. Every six months I use it and it is amazing. My teeth really do show an improvement. Highly recommend.

I no longer use whitening strips but I used these for years, they work but I wouldn't use all the time. Maybe a once a week or every two week use

The only whitening strips I use and I love them obviously. They work very well and don't hurt your teeth. Love these very much

These I leave on for 30 minutes and my teeth are instantly white. I get compliments on how white my teeth are almost everyday

We have had several patients in our dental office that We recommend this product to. All of the patients we followed Up with were very happy!
