Crest 3D Whitestrips Sensitive & Gentle + LED Light – Teeth Whitening Kit, 1 Light + 14 Treatments, Each with 1 Upper/1Lower, 28 Strips – Crest 3DWhite Teeth Whitening Strips

Product works great! I’m a little over halfway thru and have noticed several shades of increased whitening. My teeth are very sensitive to whitening products and this gave me zero sensitivity problems! Absolutely love this product and will be buying again

These are some of the only white strips I've ever used which are both effective and don't hurt my teeth. I have very sensitive teeth and can't use standard white strips without severe pain. Although there is SOME mild sensitivity with using these, it is very minor (1 on a scale of 1 to 10, compared to most which are an 8/10 or higher). Love the blue light too. I can tell a difference after even one 30 minute strip! Excellent product

Excellent way to whiten teeth in steps until you're happy with the shade of white, without over whitening them.

Perfect for my sensitive teeth...I skipped a day or 2 between treatments to let my teeth return to normal. I'm giving 4 stars for 2 reasons:1. top and bottom strips are not long enough...they don't cover enough teeth.2. doesn't seem to get between the teeth very well...not enough product. I try to press it in but it just doesn't get in there well.

Really helped whiten my teeth after all the coffee that I drink

So I really didn’t have high hopes for this product because in the past I tried white strips before and they always caused tooth sensitivity. But once I saw these, I thought I’ll try them out based off the good reviews these got. 1. Absolutely no teeth sensitivity which was a high selling point for me. 2. the led light I think is a game changer 3. I didn’t notice much of difference in the beginning but I do after the 5 day of using these. 4. They were affordable so I will have no problem purchasing again in the future. Hopefully I can can keep them white for awhile. I did make some changes to my lifestyle of drinking coffee tea and wine. All the things that stain my teeth over the years. I still enjoy those beverages but make sure I always brush my teeth after drinking these types of beverages to prevent further staining.

It’s hard to stick to a routine for me but this is too easy. It allows me to still be on the move/go while achieving the ultimate goal of WHITER BRIGHTER TEETH! I’m on day 7 now and I already see results.

The packaging for these is a joke. 90% of the time when you tear are the perforation points, because the two preforation points are only to "start" tearing it tears unevenly and a lot of the time you end up tearing the packaging in a way where you're going to need scissors to get to the actual strips and you risk cutting the strips trying to get into the packaging. The packaging needs to go back to the design board ASAP. Secondly, they boast about the stickiness of these. For some odd reason the top strips are very sticky but the bottom not so much. If you get any saliva on the bottom while trying to apply them it's just not going to stick or stay down properly. This is probably why the broader industry has moved to whitening trays because if you can only successfully apply the strips to one set of teeth - people are going to notice your "whiter smile" for all the wrong reasons.
