I’m 15 years old and my teeth aren’t exactly white, i’m thinking of buying some whitening strips product ( not the floss, or any of those other stuff) so which ones would you recommend? Also it has to be available in like a common store like walgreens, or something cuz i can’t shop online. oh [...]

I brush and floss daily, but my teeth are still yellowish. I can’t afford to get my teeth whitened by a dentist and I don’t want to use whitening strips because they haven’t helped before. I need suggestions on what I can possibly use instead and how do use it. Thank you!
I’m only 14 years [...]
