Frequently Asked Questions

Why should I use Crest 3D White Whitestrips? Why isn’t a whitening toothpaste enough?
Because you shouldn’t settle for a smile that’s just “white enough.” Every Crest 3D White® Professional Effects teeth whitening system guarantees a whiter smile or your money back. See package for details. While Crest 3D White® Professional Effects and most whitening toothpastes remove surface-level stains, Crest 3D White® Professional Effects remove set-in stains below the enamel surface for a visibly whiter smile.


The real question is why wouldn’t you use Whitestrips?

Can Crest 3D White® Professional Effects Whitestrips hurt my teeth or enamel?
No! When used as directed, it’s a safe and effective addition to your beauty routine. Crest 3D White® Professional Effects contain the same enamel-safe teeth whitening ingredient as dentists use to whiten teeth, so you can be confident that they’re safe.

How do Crest 3D White Whitestrips work?
Here comes the technical jargon: Crest 3D White® Professional Effects are thin, flexible strips that are coated with a tooth whitening gel. Designed to conform to the shape of your teeth, they work by keeping the teeth whitening gel in place against your teeth to remove stains below the enamel surface. Whitestrips use the same, effective whitening ingredient dentists use. They deliver the whitening you need where you need it for a brighter, whiter smile!

  1. RoketJ

    I prefer a whitening pen, especially for the price. It works but I did not think it worked that much better than a pen from the dollar store.

  2. Merrieha

    I used these strips for a while, but after I used them my teeth would hurt and be really sensitive, but I think that is normal for all whitening strips.

  3. NETA

    I’ve been using these for years as needed and they’re great. The newer ones like these are better at sticking to teeth, which is important. They’re certainly not invisible so I wouldn’t go out in public and expect them not to be noticed. I also do get some tooth sensitivity the next day. But if I’m not drinking coffee regularly I only have to use maybe 10 a year, so I’m fine with the inconveniences.

  4. Tal.S

    It’s good and you see it’s effectives after a couple of uses. Your teeth does get a little sensitive but the sensitivity doesn’t last long which is good.

  5. Feliezy

    I have been using these for about a week and I already notice a difference. They don’t taste the greatest but it’s worth it once you take them off!

  6. Tali

    Easy to use, whitens quite well. Recommended product.

  7. Mazzim

    The bottom strips are too long for my mouth. Therefore they are difficult for me to put in. Overall I think Crest’s whieteners are the best though.

  8. Kristyn

    No flavor is great. Only used twice so far. Had an issue with one not sticking but did whiten some.

  9. AMA

    They hands down work the best out of many strips i’ve tried. I get some sensitivity in my teeth later on in the day I chose to whiten my teeth but nothing i cannot deal with for a bit.

  10. Anish

    Yes these do work but let me tell you, my teeth are in pain. I didn’t even know my teeth could hurt this bad. But my teeth do look great.

  11. Chleo

    It is a good product for next day appearance or events. It is not super long lasting and the effects fade over a period of time. Would recommend this product if you plan to use for business meetings or date nights.

  12. JP

    this Crest whitening definitely works. I am smoker and a coffee drinker and after just a couple of uses I saw a big improvement in the whitening of my teeth. It did not make my gums sore.

  13. Serena P

    You will have a whiten teeth you never had after a week!.

    Really nice product.

    Although it’s getting yellowish one month after the full treatment.

    Thinking about getting another treatment.

  14. Justin Garcia

    My teeth are a bit whiter, nothing too noticeable. Only thing I didn’t like was that my teeth became really sensitive so I had to stop the treatment mid way. I’m sure my teeth would’ve gotten whiter but I couldn’t take the sensitivity.

  15. Gin

    These were recommended by a dentist and they work well. They brightened up my teeth quite a bit and my friend mentioned that my teeth seemed very white at dinner the other night.

  16. Diego

    I have used these many times. I have had very good results. Well worth the money.

  17. Kevin

    It does work. Eventually. There’s 20 treatments in the box. That means almost 3 weeks of applying them every day, which seems a little extreme but they’re easy to apply and it doesn’t get in your way or seem bothersome so it’s not really a big deal once you get in the routine of doing it. Don’t expect to see results in just a few days but once you’re past the second week you’ll see a big difference.

  18. Anil Blanchet

    I started to try them yesterday and the 1 hour express one really worked I am looking forward to try the 20 days challenge to see the final results
    The delivery was super fast I expected this on next Monday and I got it at the next day after ordered this

  19. Pip

    I have been using these for years and I always try the new “trend” in teeth whitening only to come back to these babies. I use the strips twice a week. I typically do this routine twice a year – maybe more if I have a big event or trip planned but when I tell you its the best and you will not be disappointed!

  20. Sandra

    This product did the job to whiten my teeth. I can noticeably see a difference in my smile. I only used half the kit and was satisfied with the results it gave.
    It was fairly easy to use. It doesn’t say on the box but the best way to keep the strips on your teeth is to first dry them with a paper towel then apply it on. Learned it the hard way when one strip went to waste because it wouldn’t stick on my teeth bc of the wetness. Otherwise once you have the strips on it was easy to go about your day and do whatever you needed to do in those 30min time frame without much bother.

  21. Savy

    Worked well but made my teeth pretty sensitive for a few days. I think it may be because I didn’t pay attention and grabbed the bonus 1hr whitening strips to use the first time. Seem to be stronger than what I get from the dentist office which costs more money, so this is a good deal. However, I’m a bit hesitant to use more often because of the sensitivity. I switch to Sensodyne toothpaste for a few days after use, but not sure that it helped much. The strips are pretty sticky and was a bit hard for me to peel off afterwards. Definitely different from when I used this same product years ago when the strips moved around while on teeth. Perhaps the regular strips would be less sensitive.

  22. Christina

    I have been using these at the recommendation of my hygienist for quite some time. They work for my needs. There is a bit of a “science” behind whitening, so I would recommend speaking to your dentist to make sure you have the right expectations for this product. Don’t forget to take before and after photos. I buy from this seller every time they have them on a discount or coupon.

  23. Kethy

    I love this product I have a really sensitive teeth which prevents me from doing any dental weighting
    I tried so many different methods and products and all of them caused me more sensitivity with no results
    But with this product I have seen the change from the first strip without any sensitivity! I love it 🥰

  24. Melissa V.

    If you want a product that is easy and works really fast then hurry up and get this. It did wonders for me and my teeth. It literally worked immediately. I noticed a difference after one use. The difference in my teeth after a month was remarkable. You won’t be disappointed.

  25. Anastasiamcconnell

    It seems that everybody wants white teeth nowadays. I have seen some people getting their teeth bleached or whitened professionally and they just look very unnatural. The crest whitening strips while the alternative I will go to from now on. I have only used them twice and have noticed a big difference in my teeth shading already. I feel like they work very well and also makes your teeth look more natural than if you go to the dentist and have them bleached. My only downfall is they are very awkward in your mouth and a little tricky to put on. But after doing it several times I am able to do it very easily now. I would definitely recommend them though they work great

  26. AMy TX

    After I used these I had hella compliments on my teeth.. they are so white now… everyone loves them

  27. Ms. Jackson

    Started to see change after a week or two after using them and the change is pretty permanent. Definitely happy with my results but you’ll definitely have to get it again.

  28. Mike Dineen

    After only 3 uses it started working great

  29. D.R

    I noticed a difference two weeks into the kit. I will definitely make this a part of my self care routine every six months.

  30. Jackie F.

    Works as long as you are dutiful in usage. Not difficult to use.

  31. The Rebecca

    If you drink a lot of tea or coffee you may find these whitening strips good for occasional whitening. I find the 30 minute strips easy to use and experience no sensitivity with them. I put the strips on before I get in the shower. The one hour strips are different and do cause me sensitivity the next day. But I will say the 1 hour strips work faster so they are definitely an option. I keep a box of these to use when I notice I’m getting more tea or coffee staining. I’m over 50 so whitening is not as easy as it used to be. These however do a pretty good job and it makes me happy to look in the mirror and see whiter teeth.

  32. Linda P.

    I love these strips. My dentist actually told me to use them less since if I needed to replace a tooth, he wouldn’t be able to match it! Whiter teeth, younger you!

  33. Adrian

    They work- plain and simple. Used these with some cheap mouth LED thing I found somewhere else on Amazon- noticeable whiter smile in less than a week. They do make your teeth a little sensitive though- if this happens, I suggest taking a break from the strips for a few days until your teeth and gums feel normal again. Overall, an amazing product, definitely worth the money.

  34. CLM

    The product is great. I have used strips in the past. It seems like the strips are not long enough because they don’t go over the back of the teeth but it also could be an error of mine. I Already have molds for my teeth from my dentist and that is what I used to put over the strips. However, they do stick very well. overall it’s a good product and worth the buy.

  35. RDF

    This product is great at whitening and you can see results already in only a few a days! I had tried toothpastes and other whitening products but none of them have worked as well or as quickly as this one. If you’re on the fence about purchasing, I would definitely recommend it!

  36. Michelle

    I had to have work done on one of my front teeth. I didn’t know how yellow my teeth actually were after the dentist had done his work..that part was white and so to match, I had to figure out how to whiten my teeth to hopefully match the “patch” on my tooth so to speak. I didn’t have any money to do a professional whitening solution that my dentist offered but I had to do something quick cause of my vanity. Anyhow, I seen these strips and the high ratings that came w/them and for a fraction of the cost. So, I bought them! I’ve been complimented on my teeth left and right since then. I never stopped drinking my coffee and of coarse, I brush my teeth at least the twice a day recommendation. I swear by them! You won’t be disappointed. The one singular draw back is occasional sensitivity but I’ll take that trade to have whiter teeth!

  37. Jamise Simmons

    I was so surprised by the results. I have tried many strips, toothpastes, and these are the ONLY ones that have seriously made my teeth white in a very short amount of time!! Definitely buying more

  38. Carol

    Easy to use

  39. Adam

    I see the reults but my teeth are coffee and tea stained. I did not take a picture.
    If I had a complaint, it would be that on one of the two one hour strip stuck to the adhesive.
    And so did two of the 30 minute strips.
    They were destroyed as I was unable to separate.
    I’m going to try another box.
    I see the results.

  40. Mahmood

    I have used these for years. They were recommended to me by my dentist. And they absolutely do work.
