The Crest 3D whitening kit is a must have for anyone who is dedicated to their teeth and oral care and wants their smile to look absolutely stunning. If you are looking to enhance your beautiful smile, look no further than this incredible product that will do just that and more

Unfortunately, I've been a smoker for over 10 years now & this is my first time whitening. Granted, my teeth weren't horribly stained to begin with. I noticed a difference within the first week of using your product. Now that I have used the entire box, there's a huge difference! Thankyou so much & keep the good stuff coming! ;-)

I really love these because they work! I have to say, they're expensive but worth it. Know I have super sensitive teeth, so I can't use them all the time.. But when I do, I only put them on for 15 mins. Not longer, or else my teeth with really hurt. I do recommend if you you'd like have white teeth within days. 

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!

The 3D whitestrips are my go to for whitening my teeth. I often get comments on my teeth because they are whiter than the average . Ive even had people come up to me and say " You have put alot of money in those teeth".They actuallly thought i had professional whitening done but I havent. Its whitestrips! Yep thats my secret! : )

This product saved me tons of money compared to the price of professional whitening from my dentist! The results were just as good as professional treatments I had received in the past but for a fraction of the cost. I would recommend using these before any big effect for the whitest smile possible.

This is the OG right here, I don't think it gets much better for this (unless you were to buy something professional). I have used this product for a few years now. It has become an "old reliable." I recommend that anyone try this product if they are experimenting with at-home teeth whitening for the first time!

After using this for a month and seeing virtually no change, I have decided that this product is not effective. I wish it would actually whiten the teeth and not just leave a bad taste in my mouth every day. It is also quite expensive as a product. Not worth it in my opinion.

I used one package per day for 3 or 4 days and I saw results! They say to use for 20 days straight twice per year so I am excited to see my ending results. Now I am just using one package every few days. I use one package at night and there is sensitivity afterwards even when I drink room temperature water. When I wake up the next morning, I feel minor sensitivity and it doesn't bother me that much. The next day or two I feel minor sensitivity but it goes away after while. I had sensitive teeth before using the product which impacts it but overall they work great.

I have been using Crest White Strips since 2001. I started while I was doing orthodonture to correct some teeth alignment issues. I could use the strips because I was doing Invisalign trays. I didn't really think much about it until I saw the before and after photos taken by my dentist. The difference was remarkable! I use them twice a year as directed a few weeks after going to the dentist for a cleaning, and I've never had any problems with teeth sensitivity or anything else. Recently I tried Power Swabs and Crest Smile Actives. First of all, if you put something liquid into your mouth, you are going to slobber! This means that you have to stand over the sink the whole time you are applying it. And if you read the directions, it says do each tooth for 2 minutes. That's about an hour if you do all of your teeth. And I did not find that they whiten as well as the strips. With the strips, I just put them on, and go about whatever I need to do until the 30 minutes is up. I swear by the strips, and with proper use, I think you will too! The more you use them the better the results. But if you are impatient and try to use them too often or for too long, you could experience gum sensitivity. My photo results are two years apart.
