Crest 3DWhitestrips Professional Express Teeth Whitening Kit with Light, 19 Count

I cannot say enough about these strips. I bought them thinking “they'll never work” but there's a money back guarantee so what do I have to lose. Full disclosure I was a smoker but quit 4 years ago. My teeth were badly stained but no amount of brushing helped. I wasn't expecting much but I was so wrong. After only one use my teeth were smile ready. If after one strip would have been my final result I would have been over the moon. I am now on my 11th session and every single session has brightened my teeth a little better than the last. I'm honestly amazed. I will definitely buy this again for maintenance. If you are questioning whether to buy this or not, buy it! You will not regret it and since there is a money back guarantee if for some reason it doesn't work for you. I can't imagine it wouldn't. If you are expecting a “Hollywood” smile I doubt you will get that. It's called a Hollywood smile for a reason, it doesn't exist except in Hollywood. That being said I'm only on my 11th session. I've taken pics of every session and each one is better than the last. Also, and this is very important, take a wash cloth and dry your upper and lower teeth before you put the strips on. If you put them on without doing this the strips probably won't stick as well. I have done this every time I used them so I'm not 100 about that but I would definitely recommend drying your teeth before putting the strips on. I can't say enough about these strips. Oh and pay the $65 to get it from Walmart. If you get it from a 3rd party seller they will probably send you an expired one or you won't get the whole kit. I think getting it from Walmart is only $10 more, this way if it is expired, not all there, or it just doesn't work for you, you can get you money back without any issues. I hope this review has been helpful and helps anyone on the fence about buying the whiten strips. You have nothing to lose. See pic for proof! Thanks for reading :)

Can't believe how well these worked - haven't used them for years and bought these on the Wirecutter recommendation. I'm floored at how much whiter my teeth are and I'm only on strip %234. I didn't have any sensitivity so far, but what a shade difference!
