Crest 3d White 1-Hour Express Teeth Whitening Kit, 8 Strips (4 treatments)

I’ve definitely noticed my teeth got whiter. I was a little skeptical in the beginning because I didn’t really see a difference, but in the end I can say they are whiter. there isn’t really a significant difference, but I think it’s probably just because my teeth weren’t as yellow as I thought they were. be careful if you have sensitive teeth though! I noticed a little sensitivity since I started using it, but not enough to stop halfway through the treatment. I didn’t feel any pain my gums. although, I do have a higher pain tolerance, so it might be different for other people.

These work great!! I did 4 treatments over 2 weeks and as you see there is quite a difference! I am impressed they do look noticeably white in just one hour they kind of do burn a little after a while but it really is not bad because it is so worth it after you take them off but it definitely is a process, you can also drink water with them on and they don't feel thick, the first pic was before I even started using the white strips and after photo is after all 4 treatments!! I wanted to whiten my teeth up before I get my braces on tomorrow I also use whitening toothpaste and mouth wash but of course I won’t once I have braces of course but it definitely works!!!

These work really well, but I wouldn’t recommend them if your teeth are sensitive! I woke up in the middle of the night with so much pain. But my teeth are nice and white. Beauty is pain.

Works but makes teeth sensitive.. ouch!

Honestly.... I'm very frugal and usually buy the cheaper stuff... but this whole.... 4 treatments @ $30ish ..... WORTH IT. I saw fabulous, very noticable results after just 2 treatments. And it lasts quite a while. Will 100% buy again when it's time.

Wow! Truly only one hour and year wiped away. After all four treatments I’d thought I have gone and paid for a treatment at a dentist. If you’re looking to sparkle these strips are for you!!!

Jan 2023 expiration date . And you use every 9 months so whatever. Thanks

Beauty is pain. These make your teeth sensitive for a few days but they make your teeth very white. I always cut my strips in half and just cover my main teeth to avoid unnecessary pain in the other teeth
