I have tried everything, but it has been awhile since I have gotten my teeth cleaned, due to health reasons and "time just flies by" at this stage of the game. I am on my 4th strip, and with each time, I kept on seeing more and more whitening. Very pleased at this point. Hoping to get to where I want them to be...fingers crossed

[This review was collected as part of a promotion.] I will always be happy anytime I get to test out crest white strips! I’m always pleased with how white my teeth turn out. The only thing that’s a little bit annoying is that you have to leave these on for 30 minutes and they’re not the most comfortable. But the results are worth it! 🦷

I love the crest strips because they are so easy. They do not run or drip like messy gels, pastes, and liquids. They're painless, and do not have a fould scent or odor either. This makes them my go-to choice for over-the-counter whitening tool kits. Crest is a brand we all know and trust, and these little strips really work. I don't know about "14" years of stains, but I definitely have noticed a difference in my smile since I began using them.

This whitening product has been effective for me multiple times over the past few years. I have used it in correlation with other Crest products (such as toothpaste) and I have seen a noticeable difference. They only negative thing I would have to report is that it occasionally makes me teeth sensitive to heat and cold, but overall, I love the Professional Effects!

Easy and fast. I put them on in the morning, and since I work from home, I am able to continue working. It does not hinder me talking in anyway and the end results are just what I want. My husband and myself split a box a couple times a year. Great product!

I've been using Crest strips for as long as I could remember . The product just gets better and better. I love the grip that they offer now. Everyone always asks me how do I get my teeth so white. I use the whole line for maximum results. Well worth the money!

[This review was collected as part of a promotion.] Crest 3D Whitestrips are an easy, affordable way to whiten your teeth at home. Most people see results in a few days, with full effects in about two weeks. They work well, but if you have sensitive teeth, they might cause discomfort. The strips don’t always stay in place, and if your teeth are even slightly crooked, they may not reach all areas evenly, leading to patchy results. Plus, the whitening fades over time, especially if you drink coffee or wine. Still, if you want a brighter smile without a trip to the dentist, they’re a solid choice!

I had previously tried the vivid white strips and seen results after a few days, i tried these out once and seen results instantly. BUT i don't have a straight smile, so when i put the strips on my teeth i was uncomfortable for about 10 minutes because i felt all drooly, afterward i also felt some sensitivity but nothing to harsh for someone who has had 2 root canals and crowns. For the most part they were sturdier than the vivid white. Although they're pricey i would recommend these.

I was really impressed with these whitestrips! I have tried them before but they always would be slippery and not stay on. The advanced grip strips were great! They stayed in place, and I was amazed that I could do so much with them on. They whitened me teeth great too - and my teeth were not sensitive at all after using the product. I would definitly use these whitestrips again!

These whitening strips are the most comfortable ones i have tried, easy to apply. My teeth have become so nice and white after using that I no longer feel the beed to use extra whitening products! They didnt cause and side effects or pro longed tooth sensitivity! I definitely think these are the best on the market and I definitely recommend them to anyone who wants a fast and affordable way to professionaly whiten their teeth!
