I love this product! As a practicing dental hygienist, I wanted to try these out so I could recommend and give my personal experience to patients. I’ve been wearing them once daily for about 2 weeks now and I am super happy with the results (and very little sensitivity)!

I had tried a different version of the Crest Whitestrips in the past but saw almost no results with them. Decided to give the Professional Effects a try and was very pleased with the results. My teeth are significantly whiter (since I had previously had bad luck with the strips I only did my top teeth at first and the difference was very noticeable after 6-8 days). The only downside for me of this product is that I did experience slight sensitivity on my top teeth and pretty significant sensitivity on my bottom teeth (in part due to previous dental work I'm sure).

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 read a lot of good reviews so I ordered the product. The shipping was great and they got here very fast but things were only downhill after that. For one, my teeth aren't very stained at all so I thought this would go great but I can only see improvement on like 2 or 3 of my teeth and even on those the results are bare minimal. The other big issue is you don't even get the full 48 strips or whatever it's supposed to be because half of the box doesn't even stick to your teeth for whatever reason. Very disappointed to say the least.

[This review was collected as part of a promotion.] I’ve been using crest whitening strips for years! I wasn’t aware of the multiple options they have available with different levels of whitening (until now!). I have sensitive teeth naturally, and I try to stay on top of keeping my teeth bright and shiny - a dental freak if you will. Crest has been the one and only brand that gives me consistency, does not compromise my teeth sensitivity, and has others complimenting on my teeth. Literally nothing else compares. I’ve tried so many! I was so excited to see these pop up on my screen.

The whitestrips were sooo much better than the previous ones I've tried (and I've tried everything). I wasn't expecting much of a difference, but as soon as I put them on my teeth, they created a really tight seal and didn't budge while I wore them! I showered in them, read in them, and could have probably done just about every aside from eating in them. It took actual effort to get them off, unlike most strips that slide around...accidentally whitening my tongue and getting goop everywhere. I noticed a difference in just a couple days and enjoyed the fact that I only had to wear them once a day!

Why is it that every other one I use has so much adhesive on it, that it is bonded to the clear plastic tray. In an attempt to remove it causes the product to distort and lacerate to the point it is too deformed to use. Considering the price of the product, one would expect better QC of the application method.

These products completely are changing my life I am in recovery now almost 3 years sober but have always struggled with appearance issues and my teeth weren't so white after carelessness and ciggerettes smoking. My teeth are getting whiter I'm loosing weight and starting to love myself again and because of this product I love my smile again.

This product is such a great & easy at home whitening kit. Great for people who want to enhance their smile & brighten the look to life superficial staining from foods & beverages consumed on a daily basis. It's easy to use when you have a busy schedule & don 't have 2 hours to spare at a dental office. I would highly recommend this product!

I have used crest over the years and it has always did what it set out to do and always a number one in my book and I had all of my children use it as they have grown up and their teeth is as beautiful as ever although they are now out on their own but not my son his teeth are beautiful as ever and I still use crest even though I have tried others but I continue to use crest because it does what it say it does protect and keeps your teeth at it's best and it is no other tooth paste I prefer other then crest.
