I like these strips because they stay put and actually whiten like they should. My teeth are pretty sensitive so I can't use them often, but a few times between teeth cleanings is good.

The only teeth whitening system I’ve used that works. I’ve done zoom before and it left my teeth splotchy and really sore, but crest isn’t super damaging to my teeth but visibly whitens

These were the first whitening stripes I’d ever used and I would buy them again! It’s a little pricey but it’s worth it! You put the stripes on daily for over a week but the results are great and it’s long-lasting!

Really do whiten your teeth. But very expensive and make my teeth feel incredibly sensitive after. Breathing in cold air after using will send pain into teeth

I use these whitening strips about twice a year (I love my wine and coffee lol) I definitely see s huge diference after the 4 th day and by the 7th day my teeth look like they’ve been whitened at a doctors office

I've had my teeth professionally whitened at the dentist and it was an uncomfortable process. I got the same results with Crest whitening strips. They are easy to put on and wear. Highly recommended.

I tried thi whitening strips for a week. I have yellow teeth. For me i didn’t really give a significant different. It whitens but only a littlebit and it didn’t last long

I noticed a difference very quickly with this product, but after three months, I feel like I need to buy another pack as stains have reappeared. Did not last as long as I wanted

I honestly dread wearing them since I hate how it feels in my mouth, but it works so well! I wore this leading up to my wedding and it brightened my teeth so much, making the discomfort of wearing them worth it.

These definitely help with whitening however leave my teeth feeling sensitive. I haven’t tried many other options so I’m not sure if it’s just this product or all whiteners.
