As a health care professional, I am always looking for products to recommend. I make it a practice to always try the product before sharing. Crest 3D White Whitestrips is a great in-home product. It is convenient.... I use it in the morning, placing the strips in before my shower and by the time I have finished my make-up 30 minutes has past. I like to use Crest 3D White Glamorous White Toothpaste before I use the whitening system. I am in my early seventies and proud to say.... '"Good-by to yellow, hello to white and youthful looking teeth."

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.

These are the best whitestrips. After using them for only 7 days (in a row) my teeth are perfect and now I just use them for maintenance. I started noticing a change by the 4th day. Well worth it especially when they have 50% off! These strips are as good if not better than professional zoom whitening!

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've had a great experience using these strips, and they have kept my teeth white for years after! I get asked all the time how my teeth are so white and I say I used crest whitening strips a couple years ago and they can't believe it! Awesome product!

I have been liking these strips! I don’t feel like they give amazing immediate results but over repeated use I notice a difference. I have noticed sensitivity before when I use them too often so I typically use one of the 30 minute strips once every two weeks or so.

The only teeth whitening system I use and I’m always getting asked how I get my teeth so white. (I also don’t drink coffee or soda that may have something to do with it) I only use this system once or twice a year and it does the trick. It’s quick and easy to use. You may need something stronger if your teeth are heavily stained.

[This review was collected as part of a promotion.] These stuck to my teeth very well. I didn't feel any slippage within the hour and didn't have a weird taste due to the gel escaping. The packets were easy to open. Directions were clear. I did notice a difference, but it was not a huge difference. Maybe using for another round would deliver stronger results. That said, I will be trying again!

After purchasing the crest 3D white strips I was very nervous to try them because I have very sensitive teeth and was afraid of them hurting after. I tried them for two weeks and surprisingly never had an issue! I am a college student and work in retail so I'm always trying to improve my appearance. These are a great, affordable solution to do so. I now receive so many complements about how white my teeth are and people even ask if I get them done professionally. I tell them about the 3D white strips and my great experience and they are shocked! Many of my friends have purchased after hearing what I had to say and they also had great results! These are deffinatly the best whitening product a person can purchase.

Love love love these! I have been using them for years, applying them two days in a row every few months. They really give the look of a very expensive clinical whitening. There is a little sensitivity the next day but nothing major and it goes away. 10/10 recommend!
