This is super easy to use. Doesn't hurt, it's not messy, and relatively affordable. I don't use this product often, only when I need it. It only takes about 30 minutes so I usually use this with a sheet mask since you shouldn't really speak as well. Removal doesn't hurt as well, I like to dry my teeth before applying for best results.

I really love these because they work! I have to say, they're expensive but worth it. Know I have super sensitive teeth, so I can't use them all the time.. But when I do, I only put them on for 15 mins. Not longer, or else my teeth with really hurt. I do recommend if you you'd like have white teeth within days. 

A must have for cigarette smokers and coffee drinkers. Price seems high compared to other brands, but I promise you'll notice the difference! Comes seperately packaged top and bottom strips. Just peel off, and place on. That simple. It suggests twice a week, due to gum sensitivity. But I typically use 3 times weekly. And have loced the results since!

Okay, I use these every once in a while. They do whiten and do what they promise. The only thing is that the strips are just an uncomfortable feeling in your mouth. They do the trick if you're not trying to pay hundreds for a whitening. You do have to keep up with it though while using these!

I used to use the DIY teeth whitening tricks such as baking soda, peroxide, coconut oil and even the activated charcoal. I could barely notice a different and did no one seemed to notice. Withing 3 weeks of using my crest white strips I heard more than once that week how white my teeth looked. Using the strips doesn't cause a mess like my other efforts have caused. It's easy and effective. I love my 3D crest strips. They are worth every penny.

I use this once a year and always get compliments on how white my smile is. The effects are long lasting and the process is relatively easy and stress free. The only issue I had with it is that at times it created sensitivity in some teeth to the point that it would be painful, but I had no issues without it past a little discomfort. Definitely the best teeth whitening system I have used 

So me and my sister got these to try them out. We where totally excited but the waiting process sucked the most. As well as the taste it left in our mouths. We tried a second time because these ain't cheap and was like okay one more time to see, am no we couldn't take the after taste at all.

I absolutely love this product! I've been using it for over 6 months now and it's amazing. I will warn those that have sensitive guns and teeth that this product may make them more sensitive the next day. Usually it's temporary. My teeth have never been whiter and it's so easy to use!

Knowing you can drink coffee or tea and no guilt feeling about the drink staining your pearl whites... 3-d crest say your back. THE feeling oh ahhh my teeth are only to be white and glowing for the holidays and everyday. feels nice someone has our backs and not our packets ... The product is amazing for the price. if you like comments about your smile this iz a product for you :)

I grew up with not the best teeth cleaning standards. Resultantly, I have had stained teeth that I couldn't do much about. I have tried many whitening aids from gels and trays to whitening strips, whitening toothpastes, mouth rinses, etc. I tried the original crest whitestrips and was not impressed. I recently purchased Crest 3D White Professional Effects, and noticed a difference after the first strip was removed. At day 3, just as the box says, a definite difference was shown. Others have noticed as well. The first day I had slight sensitivity, but I have not had that problem since.
