I use these white strips just because they’re located most convenient. With the price point you can most definitely find something cheaper that works just as well. Also if you leave on to long they make your teeth very sensitive. Crest 3D White Whitestrips 1 Hour Express Teeth Whitening Kit

I love the crest strips because they are so easy. They do not run or drip like messy gels, pastes, and liquids. They're painless, and do not have a fould scent or odor either. This makes them my go-to choice for over-the-counter whitening tool kits. Crest is a brand we all know and trust, and these little strips really work. I don't know about "14" years of stains, but I definitely have noticed a difference in my smile since I began using them.

I can’t believe how well these worked! My teeth passed the “tissue test” for sure. The only downside was my teeth are sensitive and became even more so while using these. I had to switch to a sensitive toothpaste, but I was so happy with the results. I used it two years ago, and my teeth are still whiter than they used to be. I think I’ll only use it as maintenance once every few years.

Ow. I didn’t think I had sensitive teeth until I used this. Honestly, my teeth have never been the same. I feel like any whitening I try hurts now which kinda sucks. I didn’t even finish the entire box because my teeth hurt so bad, so I never noticed if they made much of a difference. Oh well.

LOVE these whitening strips. I didn’t think an at-home system would work - these make a huge difference. Have used several times before and will use again. Sometimes teeth/gums do feel oversensitive and need to break for a day or two before resuming.

I was hoping to achieve a whiter smile with these strips, but I really didn't notice a difference after going through about half a box. The strips were easy to apply, and they stayed in place well, but I did experience some slight sensitivity. That, and not seeing any results was a bummer, so I wouldn't repurchase.

I have very sensitive teeth and was reluctant to but these whitening strips. I've tried so many other whitening products that said they would not cause sensitivity, but I also got no reults. After I used these 3d White strips I have really white teeth and absolutely NO sensitivity!!! I've gotten so many compliments on how nice my teeth look and I've just been smiling a lot more!! Love this product, definitely worth the price!!

These are really expensive and in my opinion don’t work very well. I used them everyday for a week straight and I saw no progress at all, maybe I needed to keep doing it for longer but I did not feel this product worked well. I would not purchase again.

These whitening strips are the most comfortable ones i have tried, easy to apply. My teeth have become so nice and white after using that I no longer feel the beed to use extra whitening products! They didnt cause and side effects or pro longed tooth sensitivity! I definitely think these are the best on the market and I definitely recommend them to anyone who wants a fast and affordable way to professionaly whiten their teeth!

These work really well. And you won’t have to use them that often as your teeth really do stay white after doing the recommended application. I’d recommend doing it before bed because they can hurt sensitive teeth and doing it during the day may be annoying if you’re experiencing sensitivity from it
