Crest 3D Whitestrips Professional White At-home Teeth Whitening Kit, 20 Treatments,20 Levels Whiter

I have used these for about two weeks. I have sensitive teeth so I am using the strips every other day at 30 minute intervals. I have very stained teeth from coffee. I have noticed that my teeth are 1-2 shades whiter. No teeth sensitivity yet either. Happy with my results and looking forward to continuing improvement.

I absolutely love everything about my Crest 3D White Strips Professional Effects Advanced. Not only are they convenient to find in the store, the application is super easy for both upper and lower teeth. I have absolutely zero sensitivity using this product. I buy the larger pack so that the value is maximized. I follow the instructions to a t and I consistently have a wonderful bright smile. I use these once or twice a year. The whitening effect lasts a very long time. Crest Whitestrips are the only white strips I will use.

I’ve used crest strips for a whiter smile for awhile and I find they always get the job done great! It’s been a few years since I whitened my smile again, but the fact that they keep my teeth white for this long shows what great value you get out it!! The strips are comfortable, I usually cut them in half for even more use of of the strips and less sensitivity on the tips of my teeth. I will always go for these if I need to whiten my smile!

Absolutely recommend the 3D crest white strips! They have whitened my teeth! They do make your teeth sensitive which I didn’t mind at all. I did the full first week which I started noticing a difference and after that did it a few times a week.

Purchase arrived very next day. I’m on strips number 8. Seems to be working to lighten my front teeth. Probably coffee stains. Package contains 20 sets.

I wore these for 45 mins. for 20 days and thought these alot better than the half hour ones. Now that I have my desired whiteness I will periodically use the half hour ones for booster/maintenance but need these 45 min. ones to make initial whiteness goal.

I used the first strip, and it does seem like it will whiten over time (hence the 2 star and not a 1 star review). Beware, if you have sensitive/unhealthy gums be very cautious to not put the strip on them. I had to remove the strips after 20 minutes because the gum pain was strong enough to worry me. Sure enough the painful parts of my gums turned bright white and the other areas of my gums that were healthier turned red. My teeth feel more sensitive, but I figured that would happen. I have a high pain tolerance so it really surprised me that my gums hurt bad enough to remove the strips early.

i dislike that you send my paid product in a bag, and it arrives smashed with whitestrips oozing all over. there will not be another order. send these products in boxes, so the shipper doesn't destroy it. common sense.

They don't work like how they used to teeth are still the same after two boxes 🤔 😪 idk I'm gonna try the purple ones they said those work way better.

Some of the strips don't stick to my bottom teeth. And some of them do. I've had to open a second package just to get one that sticks. It's kind of stupid.
