I absolutely love my Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit I use this when needed. You can tell the difference with one time used. I've been using this for years and and very effective. Please a reminder don't let it sit too long because your teeth can get too sensitive. I leave it on for about 20mins.

These 100% exceeded my expectations. My teeth were so stained and I used these for 2 months. They were so effective and easy to use. The only con was that my teeth were more sensitive for awhile. But in my opinion it was worth it. I would definitely recommend and but again.

I feel as if these do work and do not slip off of your teeth. BUT, I have such sensitive teeth that I can no longer use these. If you use these, simply be careful and aware that they can cause sensitivity. I would recommend these if you've never had sensitivity issues because they get the job done in brightening your smile.

I use this system twice a year to keep my teeth white. They're comfortable and don't slip and get the job done as well as a treatment at the dentist. I leave them on a little bit longer than recommended but that has never been an issue. I always use sensitivity toothpaste on nights that I use these just so I don't have to deal with any sensitivity issues.

I have been purchasing this product for about a year now and love them more every time. The very first time I used the whitening strips I was already getting compliments. I am always asked how are my teeth so white and recommend the Crest 3D whitening strips to friends. Amazing product. Highly recommend!

[This review was collected as part of a promotion.] I've always been skeptical about at-home teeth whitening products, but the Crest 3D Whitestrips Professional Effects kit truly exceeded my expectations. After just three days of use, I noticed a significant difference in the brightness of my teeth. The strips are easy to apply and stay in place securely, allowing me to go about my daily activities without any issues. One of my main concerns was tooth sensitivity, but I was pleasantly surprised to experience none throughout the treatment. The results are comparable to professional dental whitening sessions, but at a fraction of the cost. If you're looking for an effective and convenient way to whiten your teeth at home, I highly recommend giving this product a try.

[This review was collected as part of a promotion.] While I use crest toothpaste these strips did not work the same for me. It whitened my teeth a little bit, but left them in so much pain! Having to leave them on for a full hour is also super inconvenient.

I use crest 3D whitestrips. Have used the crest whitening strips for many years. I had my teeth professionally whitened years back, but that fades over time. I keep them nice & white with these strips. I've tried other brands, but they are a waste of money. Crest is the best!

I've been using these since high school (10 years) and they are incredible. They make my teeth noticeably whiter after just one use. I typically only use one strip every couple of weeks now for maintenance. The only downside is the sensitivity it causes but only lasts a day or two.

I work at a dental office got my teeth whitened 2x and glad I didn't have to pay because it really made no difference. So I decided to buy these and I love them! So much better than the "professional" stuff and didn't make my teeth sensitive like the in office whitening did.
