Crest 3D Whitestrips Professional Effects

I purchased these to use after I got my braces removed and they really did the trick. I thought I would have to use these for a very long time to see a difference and after only three days, I could see a very big difference in the whitening of my teeth. The only thing I don't like is the peroxide taste however, it will not stop me from using the strips. I will be a customer for life

Let me tell you a little story about my journey with Crest 3D Whitestrips for Sensitive Teeth. I've always been conscious about my smile and wanted those pearly whites, but my teeth are a bit on the sensitive side. So, I was excited to try these whitening strips, and boy, they did not disappoint!

The first thing I noticed was the packaging – convenient and easy to use. I started my whitening adventure, following the instructions to the letter. These strips are designed for sensitive teeth, which was a game-changer for me. No discomfort, no pain, just gradual and gentle teeth whitening.

As the days went by, I began to see noticeable results. My teeth were getting whiter without any sensitivity issues. It's not just about the appearance; my confidence received a considerable boost. I found myself smiling more, and it was contagious – those around me couldn't help but smile back.

Fast forward to the end of the 26-strip journey, and I was thrilled with the outcome. My smile was brighter, and I felt fantastic. I couldn't believe that this transformation happened without any discomfort. Crest 3D Whitestrips for Sensitive Teeth worked like a charm.

So, if you're like me, someone who wants a whiter smile but worries about sensitivity, give these strips a shot. They are effective, gentle, and, in my experience, truly life-changing. Crest, you've made a loyal fan out of me, and I'm now ready to flaunt my beaming, confident smile to the world!

Let me start by saying that I'm 28 years old and I never had my teeth whitened or even crossed my mind in doing so, I thought they look "okay" the way they were but boyyy I was wrong. This is a review with some info of my own experience using the product & to guide you on what you might expect and maybe help you with a decision. Aight, now I want to say that this product has impressed me soo much that this might be the longest review I ever wrote and no, I have not been sponsored or paid by this company, this is just my opinion and my honest review. Anyways, Crest 3D White Strips is one of those things that you didn't know you needed but trust me, this thing it's amazing. It went beyond my expectations and it's one of those products that I'll be buying on the regular from now on. Make sure that you are consistent and follow the directions when using it. The kit comes with 20 treatments + 2 One Hour Express treatments as a bonus. So it takes 20 days for the whole process plus 2 more days if you use the bonus treatments. One treatment per day and each treatment comes with 2 "whitening strips" one for lower and one for upper teeth.
Also a little DISCLAIMER : I took pictures of the whole process and under the same lighting at around the same time of the day, I tried to take the photos with the same angle but no angle is exactly the same. Due to this some photos might look slighty different and with slighty different colors. You might also notice some slight color variations but every phone screen is different. As a reference the photos were taken on a Galaxy S22 Plus. I will also label the photos so you know which part of the process they are from. The pictures were taken as follows:

1. before starting the kit (DAY 1)
2. Half way tru the kit (DAY 10)
3. At the end of the kit (DAY 20)
4.after using the 1 Hour Express (DAY 21)
5.after using the 2nd 1 Hour Express (DAY 22)
6. And last, a picture from before starting the whole kit and a picture from the very end of the whole kit including the 2 One Hour Express.
(DAY 1 & DAY 22)

So to clarify, I used the whole kit including the 2 bonus treatments back to back but I don't think you have to do it exactly that way; I think is better if you use the 2 bonus treatments down the line, maybe a few months after the regular kit to somehow "extent" the whitening effect..? I think that is the reason why the whitening effect is less noticeable on the 1 Hour Express photos than the regular kit photos.
Also on another note.. You might have seen on the reviews that you get sensitive teeth while using the kit, this is true but is not as bad a you think, at least for me it wasn't. In my experience I had sensitive teeth on some of the days that I used the kit but it goes away in a hour or two after each treatment. Sensitive tooth paste should help but dont let that discourage you cuz the end results are soo worth it !
Now, I want to end this review by saying that this product is worth every penny and I 100% recommend this to anyone. Also the pictures SPEAK FOR THEMSELVES ! I hope this review helps you on making a decision . SMILE life is good, have a good day ! :)

this product works 100% by week 2 using daily your teeth will be white or mostly white. use the whole box by the end you will have that dreamy smile. if your teeth are really bad you may need to use 2 boxes.

it whitens evenly. the only problem is it takes a little practice to apply these. day 1 i wasted 4 strips trying to get it on properly. if it sticks to the inside of your lips first you will salivate a lot and the strip will slide around all over and not properly stick to your teeth. if that happens dont get frustrated.

the product does work you just have to physically move your lips and inner cheeks and everything out of the way so the strips get applied directly to your teeth on the first go.

When Whitestrips first came out a long time ago, I bought a pack and was unable to use them because they made my teeth ache when I wasn't wearing them, and gave me sharp pains (the "zings") into the roots of some of my teeth when I was wearing them. It was pretty unpleasant with the first couple of strips, and only got worse the more I wore them so I had to stop using them and just assumed I would not be able to whiten my teeth at all.

That was a long time ago, and now that there is a "sensitive" formula, I decided to give it a try- and have been pleasantly surprised. No zings, no sharp pain, and only a little bit of aching that wasn't strong or very noticeable. I took a few days off when I started to feel increased sensitivity after the 7th strip (the halfway mark) and the pain went away and hasn't come back. I'm down to the last strip with no pain and noticeably whiter teeth.

It's hard to compare to the regular strength Whitestrips, because I haven't used the latest formulation or completed a full course, but a friend has and his teeth are RADIANT. He said he didn't feel pain and that most of the whitening seemed to show up after the first few uses, and not so much consistently.

For me, the whitening has been gradual and not as dramatic as I would hope, but I guess these are the limitations of the sensitive formula. I am happy that there are at least some noticeable whitening effects that I'm happy with and hardly any pain or increased sensitivity. I will say that the whitening is more pronounced on my top teeth than bottom, which are yellower and seem to be more stained. Honestly I don't really care that much as the top teeth are the most visible and all anyone is most likely going to see.

I am working on cutting back on my coffee and black tea habit (not only because it stains my teeth), and I'm sure that will help to maintain the whitening effects. I do plan to do another course of this sensitive formula in about 6 months (the recommended amount of time between whitestrips use) once I am done with coffee and have given my teeth a break, to try and get at more of the deeper stains.

Overall though, happy to get some pain-free whitening!

It would not be an overstatement to say that this product has changed my life. My teeth were so badly yellowed and stained that I had not been able to look at them in the mirror for years. I could see other people sometimes look at them with an expression of disgust. I had tried the Whitestrips years ago, but they caused so much pain that I had to stop after a few days, and all they did was cause some white spots, which fortunately disappeared. I had resigned myself to the fact that I had yellow teeth. The other day, after my cleaning at the dentist, I mentioned to my oral hygienist that I was not happy with how yellow my teeth were. She said that they had the $500 trays there and also Crest Whitestrips, which she said she uses. She assured me that the sensitivity goes away after a few days, and that the white spots are probably just calcium deposits in your teeth that show up first but then fade in. She thought I could get my teeth whiter. So I looked online at Crest Whitestrips and saw they now make these for sensitive teeth. I figured I would give it a try before spending $500 at the dentist. To my surprise, these are much improved from the original strips. They really stick to your teeth without any mess, so you can place them where you want without getting any below your sensitive gum line. You can also press them into the sides of your teeth. It is as if they were molded to your teeth. And they really work! Even on horrifying yellow teeth like mine used to be. After the first day, I was able to look at my teeth in the mirror for the first time in years!! I found myself putting on lipstick and smiling! With every day, my teeth have gotten whiter. I have used them for five days now, and am THRILLED with how my teeth look. They are now a very natural nice shade for my age (51). Even if they don’t get any whiter, the results have been beyond what I imagined possible. I literally keep looking in the mirror and smiling, and I feel so much more confident talking to people. I have had some sensitivity, but nothing near the pain that I remember from the original strips, and it goes away after half a day. I do use a prescription toothpaste for sensitive teeth, which I put on my teeth if I feel any tingling, but it really has not been bad at all. And I am so thrilled with the results. I can't wait to see how much whiter they get by the end of the box. Really – this product is a life-changer for people like me. Thank you, Crest!!!

It has been a few years since I've used a tooth whitening product, mostly because I dreaded the aftermath iofsensitve teeth and sore gums. I decided to give this Crest 3D kit a try. While it definitely is less harsh than other methods/brands, I still feel some sensitivity as I near the end of the course. I noticed whiter teeth starting on the 3rd day despite these strips not being as strong or as whitening as traditional kinds. You use these over a longer period than you would with other kinds.

I love that these stick to my teeth and don't slip around in my mouth during the 30 minutes per day of wear. They even require some effort to get off. Perhaps because these are sold as a "gentle" course, the strips don't have tons of ooze.

These work, just not as well as stronger kinds, but the more gentle formulation is easiest on the teeth and gums.

Last time I tried whitening my teeth was several years ago. The process was maddening and painful. The strips were a pain in the arse to handle, get onto my teeth and when I did finally mange to, it hurt like hell for days after. I've always had sensitive gums and teeth so I figured I would never be able to whiten my teeth. I decided to get brave and give these a try and I am SO glad I did! I'm only about 5 days into the box and I am relieved to say that the process has been night and day. The strips are super easy to put on and stick well. The material kind of reminds me of a thicker press and seal material (aka the best cling wrap ever made). I was very nervous about it hurting but so far I have only had minimal soreness after the first two treatments. I changed to doing them only every other day and that's solved all my sensitivity issues. It wasn't all that bad though to begin with. So far the results have been surprising! After even just once treatment I noticed a subtle difference. I had yellowing on my teeth from years of tea drinking and the yellow was at least one shade lighter. Now onto treatment #6 today and the yellowing is at least 1/2-3/4 the way gone. Amazing! I think by the time I am done I am going to be really pleased with the final result. Unfortunately I didn't take any good before pics, but suffice to say this stuff does make a difference if traditional whitening treatments don't work well for you. The only con is that I wish the lower strip was longer like the top. It says in the instructions not to switch them, but I honestly can't see why it would matter other than unneaven whitening. I have alternated placing the bottom strop slightly off to one side before as well to try to even out my bottom results. That seems to work pretty good when I alternate which side I do that on, then back to center. I will definitely be buying these again.
