I receive a lot of comments on the whiteness of my teeth, and it's literally only thanks to these guys. I've used them on and off for years, and they do just as good of a job as an in office treatment. Easy to use and easy to find, I always try to have some handy incase I want to whiten for a week or so to maintain my current shade.

My take may be a bit different. I'm 64 yrs old & don't want the super white teeth that looks good on 20 somethings. Only folks I know w/ really white teeth at my age...it's dentures & the too white often draws attention to the fact that it's dentures. Dental care wasn't as advanced for kids in the 50s and 60s so our teeth are more tooth-colored. I also have several crowns which won't change color so too much whitening of natural teeth would give me polka-dot teeth. With first box of whitestrips, I thought I'd be requesting refund cause didn't see any difference for few days but then after ~ 5 days use, there was noticeably less yellow color. I got to the lighter/less yellow tone that works w/ my crowns and now use two days in a row every week or two and it seems to be keeping my teeth the lighter/cleaner color that I want. I don't know if that's recommended but it works for me/my age/my crown situation. If you have older teeth and some crowns, you may be able to get whitestips to work for a color that makes you happy.

Good for special events or pictures when you need to brighten your teeth in a pinch. You can definitely notice the brightening by a few shades, however I find the effects do not last very long and they are a bit pricy for a box of strips. I would imagine these are also damaging to the enamel; however, they get the job done for when you need them!

These are great if you can use them for a few weeks and aren't looking for immediate results. They don't taste the best and are annoying to have on but I've found that that is the same for most white strips. I recommend these to anybody that doesn't suffer from tooth sensitivity as they can hurt a bit of you wear them for too long.

I was a little dubious at first but after a couple of uses the results were remarkable. I`ve just stopped smoking but my teeth were never that bad as I frequently go to the dentist. After 10 days my teeth are now a dazzling brilliant white and pleased with the comments I`ve received. No sensitivity at all. Easy to apply and remove when finished. Highly recommended and cheaper than other methods.

This product is really good and keeps my teeth looking great! I don't use this product often only because it's not great on your teeth using Frequently I'd say 2 twice a month. I've purchased this product many times and will continue to, the taste is a little wacky but hey it gets the job done!

I love red wine, coffee, and iced tea. The worst possible trifecta for also wanting white teeth! However, crest white strips have saved my booty on more than one occasion. Following the directions exactly from the box has made a HUGE difference in the color and brightness of my smile. A huge huge confidence boost to have whiter teeth! Best money I have ever spent.

These are my go to for teeth whitening. It works very quick. And you notice a difference within a second use. I'm not one to use them daily. I don't feel like that's necessary for me. However I do prefer these over others I have used in the past. I don't have sensitivity unless I use them a lot. Witch I don't. Would recommend!

Crest 3D White Luxe Teeth Whitening kit is so worth it! It whitens my teeth and it costs so little compared to what it costs to have done in the dentist's office. These strips get rid of coffee stains and brightens my smile! Well worth it and I love the ease of this at-home treatment!

I use Anti sensitivity tooth paste a week leading up to your treatments. I only use strips once per day for 30 min because I am sensitive. I CONSTANTLY get compliments on how beautiful and white my teeth are! The product adheres to teeth very well and I always make sure to trim them so they do not wrap around the backs of my teeth or touch gums too much. This helps with any sensitivity. The result is beautiful in only a couple of days! And after your initial treatment, you will only need to freshen up once a year. I also use the Crest Vivid White tooth paste which helps keep my teeth shiny. I have tried many products but this is hands down the best. Excellent product! Keep up the fine work Crest!
