The three whitening levels on the 3D line are visible, dramatic, and professional. Naturally, my expectations for the Professional Effects strips were very high. Unfortunately, my results have been extremely disappointing. I even went so far as to supplement the strips with the 3D mouthwash, toothpaste, and brush. Still the results are barely noticeable at best. Crest gets a point in the performance category as the new advanced seal strips do a great job holding to teeth. But at the end of the day, it’s the whitening that counts. And these strips lack the ability to whiten at anything remotely close to a professional level.

My main resining for loving these is because they don’t budge when on the teeth! These whiten more “over time” not a one time use kind of a thing. But I always get compliments on my teeth and when I tell people what I do different, I usually get a response in a few weeks saying these strips are working great for them too!

I whiten my teeth at home every 6 months because I just can’t seem to stand the sight of yellow teeth. I love to buy this bad boy every single time! It truly does its job. Even after one use, you’ll see a dramatic difference especially if you‘re a coffee drinker. A must try!

This is my third usage in 10 years. I am happy each time. I also am blessed with unnaturally white teeth and the contrast to my skin colour helps :) Most people make the mistake of NOT using the strips consecutively and therefore the results are not as great.

Whenever my fiancé and I need to whiten our teeth, we are both coffee drinkers. This is the only one that has been tried and true. It’s a little pricey, but not bad if you do it twice a year. It gives you the results you need, in not a lot of sessions.

I've used these before and each time they do the job! I went about 2-4 years in between whitening and they stayed pretty white, with just brushing with crest 3D white toothpaste! Of course, using the strips again recently, has made my smile even whiter! I do recommend the LUXE professional effects as they stick the best and perform the best.

I bought a pack of this last year and used it once a week for 4 weeks and people starting noticing my whiter brighter smile! I stopped using it for awhile because I didn't want to over whiten my teeth. People love comparing their teeth to mine. I now use one once every 3 months.

It really does the job! Whenever I have a special event or I'm wanting to impress someone, this is my go to. It's not that expensive when you look at the per strip cost and it definitely makes a big difference in how professional you look. I'm going to purchase this again and again and again!

I'd had whitening treatments at the dentist office but they didn't last long. Besides the high cost they made my teeth very sensitive. With the white strips I am very pleased. Not only do they not make my teeth sensitive but I can touch up easily without spending a lot of money.

I get asked all the time if I've had my teeth professionally bleached, and I owe these strips for that! I followed the instructions on the first box and now I'll use them every not and then for maintenance. They can make your teeth sensitive when using them a couple days in a row, so I try to prepare for that using toothpaste designed to help combat sensitivity just while I'm using these.
