I have only used one strip so far and I can already tell a difference. We all know someone who doesn't have the whitest teeth(that's me) this product is perfect for someone who is looking to whiten their smile(also me). Just a warning they taste disgusting, but pain is your gain right?

I always want these to work better than they do! I think they are fine, but they still don't give me the desired level of whitening that I want. I think the pens usually work better for me than the strips - especially for the price. These also made my teeth sensitive.

[This review was collected as part of a promotion.] I will always be happy anytime I get to test out crest white strips! I’m always pleased with how white my teeth turn out. The only thing that’s a little bit annoying is that you have to leave these on for 30 minutes and they’re not the most comfortable. But the results are worth it! 🦷

I was skeptical at first but decided to give these a try. They really did remove years of stains and whitened my teeth considerably. I drink a lot of coffee and tea and was surprised how much brighter these made them! The best part is they don’t slip once applied so you won’t taste any of the whitening gel. You can even drink something while they are on! I didn’t notice any sensitivity issues while using them.

My name is Jaclyn, I'm 24, I recently used the Crest 3D White Whitestrips Professional Effects and was simply blown away by the results. Let me first just say that I have been using Crest 3D Whitening Strips sporadically since 2007. I had a dull, yellow smile in high school, but after using the product for the first time, my confidence soared after people continuously complimented my smile. I simply love the product, and after my first use of the Crest Whitening Strips, I have never used another. My experience with the Professional Effects is simply my best yet. I have become a coffee drinker since starting my new career, and Crest Whiteing Strips provided me with my full, bright smile again with hardly any sensitivity. I am truly floored by this product's ability to continuously improve, and I thank you for my beautiful smile. To this day, it is usually the first compliment I recieve when meeting new people, and i truly have your Professional Effects strips and your 3D Whitening Toothpaste to thank for that. Thank you for giving me confidence to meet new people, and to share my smile with the world.

These are the best drugstore whitening strips that you can buy. I've been using these since I was 16 years old and got my braces off. I especially prefer the professional effects, they stay better on your teeth and I believe I see better results. If you're looking for a quick and easy way to whiten your teeth this is it. 

[This review was collected as part of a promotion.] As a person that consumes large amounts of coffee and tea, keeping my teeth white has been an ongoing struggle that has prompted me to buy just about every whitening product available. Every time Crest comes out with a new Whitestrips product I give it a try.

I just bought this product and have only used it once so far I don’t see a difference in my teeth but I hope that with my treatments that my teeth will begin to whiten like the packaging says it does. If this works well I will buy again. And it is a bit pricey.

I tried the whitestrips after lunch and just keep them attached my teeth while I was running errands. I took them off in about 2 hours, didn't notice too much difference. However, about an hour later, I looked at my teeth in the mirror, and I could tell my teeth are much whiter. It takes time for the results to kick in but definitely worth it!

I don't really notice a difference between this and their other strips in terms of results. They pretty much all work the same. I use these when I need an extra boost it quicker results. Overall I don't think the price jump is justified when I get the same results from their glam white strips.
