I am a great candidate for the use of whitening strips since my teeth are naturally less than a perfect white. I gave up coffee for health reasons but also hoped it would improve the color of my teeth. They did improve somewhat but not nearly as much as I would have liked. I’ve tried the whitening toothpastes and rinses out there with negligible to average results at best.
Which brings us to Crest White Strips. When I finally bit the bullet and decided to go the whitening strip route I was pleasantly surprised with the results. I wasn’t prepared to spend the kind of money it takes to get whitening done at a dentist’s office and my dental insurance doesn’t cover whitening. So Crest Strips turned out to be a great do-it-yourself alternative.
I will admit that my expectations for the strips were perhaps a bit too great to start. I was anticipating a noticeable change in three days as the package indicates. I did see some difference but it wasn’t as dramatic as I hoped. However, after talking to friends who’ve used whitening strips, I decided to quit over-analyzing the process and just go with the program. By doing so I found the end results to be very satisfactory. Although spending 30 minutes a day with this film stuck to my teeth took some getting used to, in the end it wasn’t a horrible process.
I followed the regimen to the letter and after a full carton of strips, I have to say my teeth were indeed noticeably whiter. They are still not as white as I’d like them to be, but they are certainly improved from where they were when I began using the strips. I plan to do another regimen and see where that takes me. If you’re willing to put $50 into a whiter smile, Crest White Strips is a great choice. I can’t say how effective they are compared to other brands since I’ve never used them, but I am satisfied with the results I got for the price of a box of strips. That’s all anyone can ask.

To start, I’ve used whitening strips before. And they’ve always worked very well on me. I never had any sensitivity to any sort of strip, so, I was confident that Crest’s newest 3D whitening strips would be fine for me. And they were!
After just 3 days of using the strips, I noticed a dramatic difference in the color of my coffee-stained teeth! I noticed the change in color both in person, as well as in photographs of myself. After 10 days, my teeth were glowing white – not so white that you’d think they were fake, just a nice, healthy white smile!
I have nothing but great things to say about Crest’s 3D Whitestrips! The “advanced seal” is amazing – no more goopy strips that feel like they are slipping everywhere in your mouth! These strips are going to be my go-to strips every six months now! These are fantastic!

Whitening strips are always being improved.
I have seen some brightening since I’ve been using these. I haven’t had any sensitivity so far which is good.
These stay on until you take them off and are water resistant to some extent.
In the past I have had professional whitening or bleaching at my dentist which was very expensive.
This saves money which is great and they are easy to use. They are inexpensive compared to what a dentist charges.
I am happy with this product and the results.

I will provide my answers – based on my using the product – to some of the more important questions concerning it, then I will explain my rating.
Q: Will it really whiten my teeth?
A: Yes. After 14 applications, my teeth are whiter but the more expensive ‘professional’ treatments produce better results.
Q: Would it be fair to say that this relatively inexpensive alternative to ‘professional’ treatments produces the same results?
A: No. See above.
Q: Is Crest’s claim that I will see ‘results’ after as little as 3 days true?
A: Yes. I was able to notice some whitening after 4-5 applications.
Q: How often should I use this product?
A: Crest recommends that you use a 20-pouches carton twice a year.
Q: Are the strips easy to apply/remove? Do they stay attached to the teeth?
A: Yes and yes.
Q: For how long do you keep the strips on your teeth?
A: Crest recommends to keep them on for half an hour.
Q: Are these treatments harmful to your teeth?
A: The strips contain a gel that is infused with Hydrogen Peroxide (H2O2). Crest claims that it will not harm your teeth.
Q: Will it hurt?
A: In my case, yes. On my second day, my teeth became sensitive to hot, cold and anything remotely spicy. I stopped and resumed after 2-3 days, as recommended by Crest. The sensitivity returned. I had to abandon use after 14 applications, following Crest’s advice to discontinue if sensitivity did not go away. Crest claims that not everyone may have such experiences.
Q: Are there any freebies in the box?
A: Yes, there is a $7 coupon that can be used with your next purchase of a Crest 3D Whitestrips Professional, Advanced or Vivid and an additional $2.75 worth of coupons to use with related toothpaste, toothbrush and rinse products.
Q: Is it okay to eat, drink, smoke or sleep while wearing the strips?
A: No. Only the drinking of water is permitted.
I had to abandon using this product after wearing the first 14 strips because the level of pain caused by the induced tooth sensitivity could not be justified by the marginal whitening of my teeth. I will not resume the treatment. Crest claims that not everyone will feel discomfort but I can only speak for myself. After 14 applications my teeth are marginally whiter but, if we are to follow Crest’s advice and use this product twice a year, one would be wearing these strips for 40 days every year or for more than 10% of one’s life. Speaking for myself only, it’s not worth it.
Given my experience, my 2-star rating should not be a surprise. 2 stars mean “I don’t like it”, which truly reflects my feelings toward this product. I don’t ‘hate’ it – after all, it did whiten my teeth a little – but this is not for me.

The package claims that you can see visible whitening after only 3 days. This claim is true. I’ve never whitened my teeth before but they weren’t too yellow to begin with and I noticed the difference after 3 days exactly. However, I also have sensitive teeth and by the third day, the strips had increased their sensitivity. The instructions say that if your teeth are sensitive, start using the strips every other day (instead of every day), so that’s what I did. The sensitivity stopped immediately after skipping a day. I used the rest of the package in a similar manner: using the strips every other day, sometimes using them two days in a row. The whitening continued just fine using this method. My teeth are extremely clean looking now, but not that fluorescent look some people get with over-whitening. They just look pretty and clean.
A few notes on usage. The strips are easy to apply, especially if you follow the instructions and put the bottom one on first. I definitely recommend, as the package says, to use them BEFORE you brush your teeth. The instructions say it will reduce tooth sensitivity but there’s also another benefit: if you use them daily before you brush your teeth, you won’t forget to do it AND you can brush off the gooey stuff that the strips leave behind on your teeth. Also, the strips are EXTREMELY sticky. They won’t come off accidentally; they stay on securely. They are comfortable to wear. When you pull them off, make sure your fingers are dry so you can get a good grip to pull off the strip.
