I loved using the Crest 3D White Whitestrips Professional Effects. They have really improved the look of my smile and everyone comments on how white my teeth are now! My patients that have tried these have also been very satisfied. I would recommend them to anyone who is looking for a bright white smile!

I got these white strips to use before my wedding and the results were amazing! I definitely achieved a brighter smile with this product and lasting results! I would totally recommend this product and believe it is a great price for how well it works!

I love how the Professional Effects White strips adhere to my teeth for the whole 30 minutes. This allows me to continue multi-tasking, while easily whitening my teeth. I also love how I notice immediate whitening effects after using the products only a couple of times. I would totally recommend Crest 3D Whitestrips and plan on purchasing these for my sister for Xmas. #3DWhite

I used to love these whitestrips when they were in the purple box with the Luxe line. They were my go-to and I always noticed a difference within a couple of days after I wore them. These new packaged ones are garbage and do absolutely nothing. So disappointed.

I recently had a root canal, which resulted in a crown. My dentist asked if I bleach my teeth? I explained I only whiten with Crest WS. He said my teeth were so white, he had to submit a special order to whiten my crown even more in order to match. He was very surprised that I've never had my teeth "professionally" bleached... THANKS CREST WS!

I used the Crest Classic Whitening Strips previously and had great results (didn't even need to use the entire box at one time to get the results I wanted). I was quite disappointed that the Professional Effects did absolutely nothing to whiten my teeth. They did stay put much better, however. I do not have subborn stains or overly yellowed teeth; I'm not a smoker but I do drink coffee. I just wanted to give my smile a brightening boost. Unfortunately, I will be looking for other whitening products unless the Crest Classic Whitening Strips return to the market. Luckily I was able to get a refund.

Loooove these whitening strips!! Toothpaste and brushing your teeth can obviously make your teeth white, but sometimes perfect hygiene doesn't even completely do the trick. So then comes crest whitening strips to save the day! I've heard people say they're teeth hurt when they leave them in for too long. I've never experienced this problem, but make sure to follow the directions carefully to avoid any pain! Overall, I recommend.

[This review was collected as part of a promotion.] The Crest whitetening strips are a very easy to use product to create a brighter smile. They come with a very sticky adhesive that will firmly stay on your teeth for the 45 minute duration. After the first use you can already see a benefit. The only thing is that my teeth are quite sensitive, so I cannot use this product everyday.

I have received my package. I’m at my third treatment so far no results. However I’m very confident it’s too early to have noticiable results as my teeth are not extremely stained. But looking forward to whiter teeth after my active braces treatment. The only confusion I have is that I have just noticed than in this website the suggested time per treatment is 30 min. However in the box says 45 minutes. May I please get assistance on how many minutes should I leave the strips on.

These are amazing. Everyone should purchase this product! Crest whitening strips work wonders and actually make teeth whiter. They are kind of pricey but super worth it in my opinion! I am a coffee addict so these whitening strips are a staple for me.
