I used these when I got my braces off, and while I saw some results... they weren't drastic. Probably not worth all of the money. If you want whiter teeth immediately I would use the Hello Activated Charcoal Fluoride Free Whitening Toothpaste With Fresh Mint Coconut Oil.

Use these strips if you want pearly whites! I usually use them once every other week, and that's plenty. Your teeth may get a little sensitive the next day, but it's worth it. You get a good amount of strips and they're very effective. Highly recommend.

I love these. Over using does hurt my teeth but I use them once or twice a week and my teeth stay so white. I also use the same toothpaste. It's a bit expensive but it lasts you for a while and the white lasts longer than any other whiteners I've seen.

Starting using these white strips about a month ago and wow! In just 30 days and I've noticed my teeth are significantly whiter and brighter. I have kind of crooked teeth so the fact that these helped my teeth become whiter definitely has boosted my confidence when it comes to smiling with my teeth.

These strips are AMAZING! I used them every day, for the 30 minutes, and when the pack was gone (actually even after the first use) my teeth were SO much whiter than they've ever been. The strips also don't slide or slip and have great grip so you're able to talk and not feel like you have to keep your mouth super stiff to avoid having them slip off.

Why spend big bucks going to a dentists office for whitening when you can get great results from the Crest 3D White Whitestrips Professional Effects? I tried them and received instant results that were amazing. I'm 69 years old and the lifetime of stains disappeared quickly, and completely. This product is outstanding.

I love these! They work so well and actually stay on your teeth opposed to sliding around. The only negative I have in regard to these is that fact that when I say they stay.....they stay! Peeling them off takes some effort and you're left with the residue from the “glue”. Other than than, I love using these!

I absolutely love crest white strip‘s because they really work. I got the professional ones before my wedding because you don't have to pay professional prices to get professional results with these. I didn't even use the whole box but my teeth looked super white and ready for my big day. I will always use these white strips.

I love this product! My teeth have gotten so white compared to when I first started using this product. It has surpassed my expectations. I have not used any other brand so i cannot compare. But i have been so happy with this product that I have not even thought about trying another one.

I started using the whitestrips a few months back and loved the results. Everyone noticed the difference and gave me compliments all the time. I did have sensitivity but just went from using everyday to every other day to once a week. Once my teeth were as white as I liked it was fine to only use them once a week to maintain. My sister was a bit jealous of my results since we were always known as twins even though we are a few years apart we look so much alike. Our teeth on the other hand were now very different. I gave her just three strips to use and now she has purchased her first box. We are now both lifetime costumers. Thank you so much Crest for a great product!
