they work really well! I use these on occasion and I notice a difference in color! my teeth look whiter after using them. anytime I go to my dentist they always tell me that my teeth are super white. they do make my gums feel kinda uncomfortable though, so I don’t use them too often. Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit

I use these once per year for two weeks (don’t skip a single day) along with a regular whitening toothpaste when I brush twice per day. Ever since I began using them, I get compliments about how white my teeth are. Every six months at my cleanings, my dentists and without fail they have each commented on how white my teeth are. Never had a professional whitening procedure done in my life. So they DO work. I’m a non-smoker and seldom drink dark teas/coffees

These work! I use them very, very rarely, like maybe once a month. I like that it only takes 30 min and my teeth definitely look whiter after. They do feel sensitive when the strips and on though, and that kinda freaks me out. I don’t think I would use them as frequently as they recommend.

Absolutely love these things ! I use these at least twice a year and love how simple and easy they are . They definitely make a difference in my teeth, specially when you use them three days in a row , I like to use them just to give my teeth a pick me up of white after all the coffee I drink .

My teeth are very sensitive when it comes to whitening strips so when it comes to them I tend to be super careful. I only use these once a week and I can see an amazing change in my teeth! They aren’t to harsh but I would definitely recommend for anyone wanting whiter teeth!!! Plus, it does not take up a lot of time throughout your nightly routine.

I use crest 3D whitestrips. Have used the crest whitening strips for many years. I had my teeth professionally whitened years back, but that fades over time. I keep them nice & white with these strips. I've tried other brands, but they are a waste of money. Crest is the best!

I used these when I got my braces off, and while I saw some results... they weren’t drastic. Probably not worth all of the money. If you want whiter teeth immediately I would use the Hello Activated Charcoal Fluoride Free Whitening Toothpaste With Fresh Mint Coconut Oil.

They work really well but I do want to throw out a pretty major disclaimer - unfortunately I have really weak enamel so I have a fair amount of fillings. If you have fillings on your front teeth unfortunately this product will cause the. To sting with pain days later. Yes, it very well helps to whiten teeth very nicely but personally it is not worth that stinging pain on the fillings.

I love love love the new professional whitening strips, I had some sensitivity after 5 days of use but my teeth were so white I really didn’t need to use them more then a couple day.... they work miracles, I will always go for these over anything else ...why waste more money on anything when these 100% work

For someone 73 years old, this does a fairly good job of making my teeth look less yellow. However, the other day I opened one of the packets to remove the strips, and the strips came away with the back still on them. Perhaps someone could separate them, but I could not, so I opened another packet. I was able to release the upper strip but not the one for the lower teeth. This is a rather expensive product to have to throw away. I would mail these to you if requested to do so. In the meantime, the numbers at the top of the packets: (L)4003V435 Thank you
