Crest 3D No Slip Whitestrips Professional Effects Teeth Whitening Kit 20 ea

I will be the first to say that this product is not for everyone. For those who have the right type of enamel that is strong and not overly porous you should notice a dramatic whitening effect. I have given this product though to my family members and they have very mixed results. For my sister-in-law they actually highlighted the discolorations of her teeth which was really disappointing. She drinks a ton of coffee and has soft enamel. So while this whitened some parts of her teeth it did nothing to others. She tried this product twice with the same results. My dentist literally cannot believe how reactive my teeth are to this product. I actually have professional whitening trays and this product works better for my teeth than doing professional whitening. I do have severe sensitivity and gum irritation when using the professional whitening gel and trays. So that is why I consulted with my dentist as to what he recommended for me. Do not get me wrong, the professional trays got my teeth white, but I did not want the side effects that came with it. With that said, I strongly recommend consulting your dentist before trying this product especially if you have a good dentist patient relationship. I believe they can definitely tell you if over the counter treatments will be effective based upon your teeth and dentition. If this product is recommended for you then definitely try this whitening kit. Since my teeth are already white, I use this kit as a touch up twice a year. I always get a good expiration date with a lot of longevity when I buy this product on Amazon. You definitely want to always make sure you have a fresh product whether you buy this on Amazon or locally. So check the expiration when you receive or before buying. I personally could not beat the Amazon pricing locally for this product. I also love that Amazon offered me a coupon when I put it in my car so I saved even more than I first expected. This arrived quickly to my condo. These strips stay securely on your teeth until you pull them off. I always use a paper towel or tissue when I pull these off. If not the tips of my fingers will get white from the whitening gel. This usually goes away after a day or so. But if you use a paper towel or tissue you should not experience this. I do not have pain in my teeth or gums after using these. I do experience dry mouth and tongue though the day after. So I really try to stay well hydrated when using these. Sometimes I also get chapped lips but that side effect goes away 48 hours after I am done using these. I also like that this product does not have any after taste or chemical taste when there are in your mouth. This product definitely works better if you do not brush your teeth before using. Of course make sure your teeth are clean so swish some water before placing these on your teeth, but this product works better for me personally if I do not use them immediately after brushing. For those who say they experience side effects or do not get a level of whitening they expect then I recommend making sure you are following the directions to the letter and if you are then contact Crest for a refund. Just make sure you have proof of purchase. Good luck if you decide to try these. I hope they work for you as well as they do for me and that you get a super Amazon price too!

I cant believe i was discouraged to buy this product after reading these reviews. In the end I'm so glad I did. This product has AMAZING effects for an at-home whitener hands down. I think a lot of the grievances in these reviews come with inexperience in teeth care and teeth whiteners in general. For example, DO NOT use toothpaste before applying the white strips, for it effects with the whitening process. A few things i'd like to note: 1) To the people saying "This product doesn't whiten all of my teeth" You do realize, that you cannot just put the white strip OVER the teeth? Teeth aren't bricks. You have to fold the strip into the teeth. For example, I start in the middle of the whitestip, put my finger on it, and smooth it out over my teeth towards the ends MAKING SURE it forms to my teeth. Besides, Even if it does not touch every part of your teeth, the gooey whitening agent, once reacted, will cover all of those spots and form to your teeth. (especially if the strip is able to cover the backside of your teeth too, if not it's sstill fine.) 2) To the people saying "It hurts my gums/teeth/" Well, with the gum thing, do not under ANY circumstance put this on your gums!! You're supposed to get it close, but not actually have the strip cover the gums! I did this one time and my gums HURT. From then on I didn't have it touch my gums and discomfort disappeared. 3) To the people saying "not good for sensitive teeth" This one was a big deal breaker for me at first. My teeth are incredibly sensitive; eating ice cream hurts. I find it odd that I found no sensitivity as all with this product. Food for thought. Regardless, I achieved great results, my teeth are shades whiter, but not that nasty florescent white. It looks natural. For anyone interested in my routine: 1. 30 min after eating dinner I quickly run my wet toothbrush across my teeth (No toothpaste! This is important! The toothpaste can react with the whitening process) 2. I apply the whitestrip bottom first, starting in the center of my teeth and smoothing it out as far many teeth it reaches and fold it over the back of my teeth. 3. Same with the top 4. Press the strips in again, making sure they are activating and are on correctly (sometimes on the bottom teeth, saliva can make them move around, gotta go fast!) 5. Set an alarm for 30min since I am forgetful 6. After 30min, remove bottom, then top and brush teeth as normal. After the 20 day regimen, I now use Activated Charcoal to keep my teeth this shade of white. It's inexpensive and is a natural teeth cleaner/whitener. Look into it!

Crest has been the most consistently reliable and effective whitening strip's I've tried. The results start becoming apparent even after 2-3 uses. It does cause a bit of sensitivity but using a sensitive toothpaste has helped. Highly recommend!

These absolute work great. Felt like my teeth looked remarkably whiter after one use. However, they made my teeth hurt like hell for days after. Not my gums, my teeth. Helpful info: I have hard, non porous teeth. I also had EDS which effects the teeth.

I left an almost identical review for another iteration of this product. I will probably continue to order the different variations of this product until I find the one I like best... My dentist told me to use Crest Whitestrips - he specified the brand - before deciding if I want to do a professional whitening. It was a good call because he's right - I can do the job myself and get good results. There was a bit of a learning curve for properly using these strips - I went online and checked for tips, the best one being that you should wipe your teeth very well before applying the strips - but once I had the routine down, it was a cinch to use them. This package contains a 3-week supply, and I have been using them for about a month with great results. I will be ordering more - my dentist said I should use them for 6 weeks, and I will want to to keep some on hand after that for periodic maintenance.

This is my third time buying this. First off, great product! I usually use 10 treatments every 4 months (because Crest states the max is 40 treatments in 12 months). Spacing it out has done wonders. It usually take me 5 treatments before I start seeing immediate results. I used to be so embarrassed to wear a white shirt or I would wear one but not smile as much to avoid the huge contrast. I also figured out ways to combat sensitivity. First, realized I shouldnt brush my teeth at least 3 hours before using the whitestrips. It's actually best to use (IMO) if you don't brush your teeth at all in the evening/night. So the nights I used it, I only brushed my teeth at breakfast and sometimes lunch. Second, I gargled with hydrogen peroxide routinely and this helped with sensitivity and increased whiteness. Third. I noticed the height of my bottom row is short in comparison to the top. When the strips laid on my gums, it would cause a negative reaction... almost like a dull aching pain/soreness. So before I put on the strips, I used scissors to carefully trim the top of the strip off. This allowed the strip to stay ONLY on my teeth and not rest on my gums. It's amazing how many people positively comment on my teeth. I think everyone's so used to dingy white and/or yellow teeth that white teeth truly stands out! I have gone to cosmic bowling, glow in the dark golf facilities, as well as other low/special lit events and I've had strangers comment on how white or "nice" my teeth look. Mind you, my teeth have shifted from not using my retainers much so I knew they mustve been talking about the whiteness of my teeth. It's great to stand out this way. It definitely boosted my confidence and now I'm hooked to these strips! I have at least two youtube videos (look up Naturallyjoli) describing my day by day experience with my first treatment as well as a detailed teeth hygiene regimen for those that want more details before committing. I rarely drink colorful drinks (from time to time I may sip wine or juice). The drinks never stained my teeth longer than a minute or so. Actually, my lipstick stains my teeth more than drinks and it's not a permanent stain (I'll lick it off and it's gone). I was so hesitant to use this product before (I kept reading reviews and it scared me). But I am happy I finally gave in. Now it's been a full 12 months since I started and I felt this was the perfect time to give a review. I look forward to seeing how much more white my teeth can look!

I am simply amazed by this product. I tend to be skeptical (and cynical) about just about everything, especially products that claim they'll increase whiteness by "three shades." (What the hell is a "shade" anyway?) Well, whatever a "shade" is, I got a zillion of them. My teeth are GLOWING after about four days of use. They even whitened my porcelain crown -- something I didn't expect, since it wasn't nearly as stained as my natural teeth and I figured it must still be the original color. The product is convenient, they STICK so I don't have to mess with them, and they leave my teeth feeling slick and looking awesome. I AM SO PLEASED! I just put them on before I lift weights in the morning and take 'em off before I brush and head to work. Easy breezy. I drink a lot of coffee and red wine (for the vitamins of course.) As a result my teeth really started to look terrible. I didn't notice it in the mirror so much but in pictures they always looked like crap. I kept thinking I would go to the dentist and have them whitened but then you have to take time off work. What a hassle. These are easy and they work. I just can't emphasize enough how happy I am. They do make my teeth hurt, but my teeth are naturally sensitive anyway so I brush with Colgate Sensidyne. I think it's important to put the strips on before you brush, then brush with desensitizing toothpaste immediately afterward. I haven't stopped using the strips yet but I suspect my teeth will slowly return to their typical level of sensitivity after I'm done with the box. I can easily do this once every few months if necessary. Totally worth it. Extra points to Crest if they decide to make whitening strips that already have fluoride in them so you don't have to use desensitizing toothpaste afterward. Another downside if you can call it that: The top strip is only wide enough to cover the smile of someone with a mouth the diameter of a broom handle. A lot of the yellow in my smile was on the front side of the rear molars which you can easily see whenever I open my gaping maw. The solution of course is to put the strip across the rear teeth on alternating days. You have to be especially careful not to get the rear side of the strips wet with saliva as you do this or they won't stick. It takes a little practice but it's worth the trouble. None of this came as any surprise. I did my research before buying the product. Anyway, definitely five stars.

I am 11 treatments into my 20 strip box, and so far, the results have been OK, at best. I used crest strips YEARS ago (10+ years) with similar results. At that time, my dentist told me that some people just don't have white teeth, after I asked him about an in-office treatment attempt due to the lackluster results from the white strips. It's not a matter of stains or wear, but just the natural color of some teeth is not brilliant white. He said those people would benefit for from bleaching as opposed to the peroxide treatments, as that's the only way the teeth would get 'white,' but bleaching can cause other issues. I had that in mind when going into this recent use, but figured I'd see if the results would be the same with the stronger, improved product. After the eleven treatments over 11 days, I am seeing SOME change. More of just a homogenization of the color as opposed to a super-whitening (which tells me the product is helping with some stains). There is some lightening as well, but it's not an 'expected' result based on the product claims (not even sure if qualifies as a one-shade whitening). I am starting to get some sensitivity now, but plan to continue the treatments until the end. I'll just use toothpaste for sensitive teeth to mitigate the sensitivity. Not expecting a miracle by the end of the cycle, but I'll see if the results improve at all. Just heed my story about what my dentist had told me, and temper your expectations for the product. UPDATE: I used the product down to the last strip (OK, OK...my wife used 1 of them before a vacation trip), and I can say my results above never improved. 'Whitening' was minimal. That's not to say the product didn't work, but as I pointed out above, I just don't have teeth that are going to get that luminescent whiteness. I think this will be the last time I give these a try, at least for another 10 years.
