The whitening strips are the best thing ever. They don’t taste very good though so I put my retainer over it and it does the trick. I put them on while I’m doing my makeup and by the time I’m done my teeth are instantly whiter. Just make sure to brush your teeth before and after.

You buy products and are never sure they are going to live up to the claims it states on the packaging. This product does exactly what it claims it is supposed to!! Money well spent and wonderfully white teeth result just like going to the dental office!

I was impressed by how quickly my teeth were whitened after using this product! My teeth were very yellow the first time I started using these white strips and after 3 uses over a few months, my teeth were glowing white! I got so many compliments that I knew the results were not just my hopeful imagination. Would definitely recommend!

These teeth whitening strips genuinely work. I did not give a full five stars only because of the expensive price. I also have relatively sensitive teeth and my teeth definitely hurt a little bit in the cold or when drinking cold liquids. Worth it, in my opinion.

These are pretty incredible for lifting the coffee and wine stains that build up on my teeth very quickly. I think they are easy to wear and don't slip and slide. I like to put them on while I take a shower and blow dry my hair/put on makeup. They give a noticeable difference. I removed one star because I have sensitive teeth and I DO notice that my teeth feel sensitized for about a day or two after I use these. For that reason, I only end up using them about once or twice a month.

I have average kind of yellow tinted teeth and decided that needed to change for a photo shoot I was doing the next day! I tried these because of a friends experience and I noticed the difference that day! Love this and recommend it to anyone looking for a teeth pick me up! Especially for broke college students like me!

I recently tried these for the first time. I heard that my teeth become sensitive but they didn’t. I would say that my teeth went from not white to semi-white. Overall I’m satisfied but I definitely need to buy again and do a second time to get the full effect.

I have tried other whitening treatments that did not work at all, but Crest whitening strips absolutly whitened my teeth in only 7 days. The intructions said to use it for 20 days but I stopped after 9 days since my teeth were already so white. I will use it again in a few months to keep them white. Very happy with results.By the way I am 68 years old

This is my yearly or bi-yearly go-to whitening product! They just work! I stopped using them for years because they do make my teeth a bit sensitive, but after trying several other products (that didn’t work at all) I came back to these! Even though I only use these about every other night (sometimes every third night) due to sensitivity issues, the end result is still always amazing! Interesting tip I learned from my dentist years ago: just because they recommend you take them off after 30 minutes, does not mean they stop working after 30 minutes! To get more bang for your buck, you can leave them on a bit longer to get more whitening. Due to my previously mentioned sensitivity, I just add on an extra 5-10 minutes each usage.

I’ve only used this set once, mostly due to the high price. While it does whiten your teeth pretty well for being something you can get at the store, it did make my gums hurt/burn when the strips were on. This discomfort is not awful, but it seems like there are other ways to whiten teeth. For the price it does it’s job, but be warned about the burning.
