My fiance and I used these before our wedding. I only used them twice and I still got a lot of comments about how white my teeth looked. We bought the professional effects and planned to split them, 10 days of treatment each, which made it a good value for us.

I liked the results that I got from this kit. I didn't get any sensitivity from doing the kit, which I have gotten from other whitening kits. I am a tea drinker, so a good whitening kit is a must! The only tho g I wasn't thrilled about was the price, but it's worth it because it worked

These strips are amazing. They're so easy to apply and they work really well. After about 5 uses I notice a big change. Although they leave a slight sensitivity, it is nothing like what I've experienced before with competing products. It normally subsides within a few hours. If you're looking for a fast and easy way to whiten your teeth at home, this is your best bet.

I have always had a problem with whiting strips not working. This product did not meet my full expectation but I did see some results. I would recommend this to anyone wanting small results but if you want your teeth really white this is not the product for you.

These definitely help whiten my teeth after just a few uses. My only issue with them is the price, but for the results it worth it. I only use them before I have an event like prom and usually do it the 14 days before and they stay white for a little over a month after!

i am a dental hygienist, and i would highly recommend these to anyone who wants to lighten the color of their teeth. these will work more effectively on someone with yellow undertones rather than blue undertones. as with all whitening products, these may cause temporary sensitivity. these are a good option for whitening on a budget. we recommend our patients to use the strips 1x a day for 12 days to achieve a whiter smile. as time goes on and your natural tooth color reverts back to normal, you can whiten for a few days to achieve whiteness once again.

After just one use my teeth were whiter. I use it twice a month or so. Maybe more if I have an event coming up. I have sensitive teeth but I don't have any sensitivity using these! Price seems high until you price a professional whitening treatment at the dentist. Trust me. The previous version of these slipped around as soon as you put them on. They will not stay put if you were trying to talk... The never version is “slip proof”. They have a better grip to the teeth to start. I still don't like to talk too much with it on.

Crest Whitening Strips are absolutely incredible, my friend! They work wonders in brightening your smile and giving you that extra boost of confidence. Just pop them on your teeth, let them work their magic, and voila! You'll be flashing those pearly whites in no time. Get ready to shine! ✨😁

Absolutely love these whitening strips! They're perfect to just put on while you do your makeup and take off and they leave you with a pearly white smile! They do unfortunately make your teeth a bit sensitive but all whitening products do that. Highly recommend !!

I bought these because so many people swear by them but unfortunately I didn't get the results I was hoping for. They made my teeth incredibly sensitive so I couldn't use them every day which may be the reason I didn't get good results, but they were disappointing on the whitening aspect. I will be looking to try a different product next time.
