Crest Whitestrips Advanced Seal
Quite Impressive even when compared to Pro products
I am making this comparison to Opalescence 35% professional gel that I used in dental trays about a year ago. That was I believe the highest concentration of hydrogen peroxide (the common bleaching agent used in pretty much all the whitening products) readily available through mail order. They also offer 15% and 20% I think. At the time I went overboard testing its effectiveness by taking photos of my teeth before and after each treatment under fixed white balance setting and comparing the results with the color picker tool in a drawing program. Yes it worked and it worked well. However filling the tray was a pain and remaining pretty much motionless for half hour at a time was more of a pain. Add to that the fact that your mouth is constantly producing saliva, which you do not want to swallow so it drools down your cheek. Sorry for the graphics but to be helpful with the review I feel its important that you understand the do it yourself alternatives. My teeth color is only very slightly off white due to tea, coffee and wine. I would have to repeat the treatment about every three months to keep a natural (not bright) white appearance. After I ran out of Opalescence, I did not re order due to the involved treatment procedures. Hence the White strips. The regular , not "advanced", products are just as much of a pain due to the fact that they will not stay on. The advanced strips stick on like Velcro. I usually dry my teeth with a paper towel first to make sure the bond is good, and have had them stick for an hour with no problem. As soon as you stick the strips on you can see the foaming hydride start to do its work. Surprisingly I found the whitening achieved after 1 hour (30 min recommended) to be a close equivalent of the pro gel. There is no peroxide concentration spelled out anywhere on or in the box so I would guess that it is below the 15% offered in pro products, but the close proximity of the gel to the teeth without any saliva dilution makes up for some of that. Crest recommends that initially you should use them twice a day for best/fastest results, I would agree with that. I use the strips to maintain the color only now, so one application (out of the 14 sets in box) per month will last a year. Crest recommends that you use two entire kits of 14 per year. Here are additional things you should know:
1. Not one of the 14 foil packs containing the strips opened up correctly by pulling where the arrow shows. It rips above the seal. Don't try to do it from the other side, just get scissors.
2. The top strip is just 5/8 by 3 inches long. That is too short in the up and down direction for me. I have to start applying the strip at the top of the teeth by the gum and there is hardly any left to wrap around to the back of the teeth. Another 1/8" please?
3. After you apply the top and bottom strip, gently use the tips of your fingernails to push in the strips between the teeth. Quite often these areas are most discolored.
4. If you have any tartar buildup, have it removed/scraped first. The contrast between it and tooth enamel will be exaggerated by the whitening process.
5. When its time to remove the strips, it is a bit of an ordeal. They really stick very well, but do peel off easily if you start at a corner and youse your fingernails for a good grip. When the strip comes off, there will be remnants of the glue and gel stuck on your teeth. Don't panic, but I wish the instructions would have mentioned this. It will dissolve completely after about 5 minutes.
6. I had no tooth sensitivity issues at all.

YOU SHOULD TOTALLY BUY THESE WHITESTRIPS IF YOU REALLY WANT WHITER TEETH. Don't whine about sensitivity, it says right on the box that it can happen. I had no issue with the "goo" on these bleaching my clothes or fingers. They only became gooey when I removed them from my teeth.
I had been thinking about whitening my teeth for awhile -- I had the Rembrandt 2-Hour Whitening kit, but that thing TORE MY GUMS UP. It did whiten my teeth slightly though, but not worth the $50 and the pain. I asked my dentist about getting professional whitening, but he said it's basically the same thing as everything out on the market that has a tray (like the rembrandt kit), just wildly more expensive (I love his honesty).
I had the old whitestrips from about 3 years ago -- they didn't do too much for me. I got this new set of Crest Whitestrips in a fit of optimism. The shipping took a little longer than most stuff I get from Amazon, but nothing outrageous. The packaging was nothing to hoot at (mine came wrapped in the Classifieds section in a manila envelope, the box was a little crushed, but the innards were fine).
I read the instructions, and DID NOT brush my teeth beforehand, and slapped those suckers onto my lower and upper teeth. I like these better than the old whitestrips, they aren't gooey and slippery like the old ones. They're more a tacky feel, like they get sticky only when they get wet, so you can readjust them without them sliding all over your mouth. I do have a fairly wide smile, and the upper strips cover just about all of it, and the lower ones cover about 6 of my teeth. These don't taste as bleachy as the old ones, and they didn't irritate my gums AT ALL either.
I've been using them every other day to cut back on the risk of sensitivity (but I fell asleep with them on one day, which you're NOT supposed to do - so i ended up leaving em on for like 2 hours instead of just 30 minutes, so I had some sensitivity after that session that faded eventually). I noticed a visible difference in the shade of my teeth within 3-4 treatments and I think i still have about 5 packets left. My teeth are pretty white now, but not unnaturally white (by unnatural, i mean like Ross in that episode of Friends where he dates the girl with the blacklight). My teeth aren't paper-white, but let's be honest -- that would be creepy. The walls at my job are a pale cream color, and my teeth are now whiter than the walls.
The only thing that could make these better is if they paid my bills and told me they loved me once in awhile.
Oh, and maybe included a whitening scale, so that you could compare your teeth when you start to when you finish.

I Noticed results in 2 days personally. I only used the sample... However I gave this 4 stars instead of 5 stars because whenever I use any products that whiten your teeth. Mine become extremely sensitive for the next 3 or 4 days. I tried for a week to do it every other day... Nights only. And it still worked well. You can even use this product once a week if you wanted.
I would suggest using Enamel building tooth paste AND mouth wash to help with sensitivity.

I only used half and my teeth looked great. I whiten my teeth once per year with this. It works great.

Dang, reading these other reviews, I feel like a freak. I agree with everything the other reviewers have said regarding the stickiness: these strips do hold much better than the old ones, and are quite unobtrusive. I have somewhat prominent canines, but had no problem wrapping the strip around them and tucking it into the crevices between teeth.
The only problem is, it didn't do much to whiten my middle-aged choppers, which are rapidly declining into the yellowed ivory of an old piano key. Rats! I don't smoke and I don't drink much coffee. I even gave up soda drinking recently (for the sake of my dental health, not cosmetics). Maybe it's that these strips work better to remove stains than to reverse the yellowing that comes from age? In every other respect, these were winners. But what can I say? They just didn't whiten my teeth!
I think I'll give it a try for one more box's worth and see if my once-pearly teeth just need more applications.
(EDITED TO ADD: Well, the first few strips of the second box finally produced noticeable whitening. What's more, my daughter tried them, and her smile was visibly brighter after three days. I don't feel like such a freak anymore :-)

For reference, this is the first time I've ever attempted to whiten my teeth. I drink coffee and soda occasionally (1-2x a week or every other week.) I am also Asian, so a lot of my meals include sauces that can stain teeth (i.e. soy and duck sauce). My teeth also have a bit of worn out enamel.
- Easy to use
- Effective (lightened my teeth about one shade)
- After taste not that strong (the after taste wasn't bad, but I experienced a phlegm like buildup when I swallowed the foam. So after the first day, I decided to spit out my saliva every 5-min while using these).
- Instructions too vague (didn't mention when you should eat/drink/brush teeth. In my case, I waited 1-hr after/before eating to use this and brushed my teeth afterwards).
- Lower strip too small (it would be nice if it covered more teeth; it covered 6 teeth for me but only the 4 middle teeth actually whitened).
- Tooth sensitivity (I did experience sensitivity for the 1st week; it wasn't so bad the 2nd week. It felt like my teeth were weak, kind of like when you first have your braces removed or when you first use a retainer -- I couldn't drink really cold or hot drinks / chew on hard food).

I used this product three times. First time I used this strips it was okey. The second time was a disaster. I felt acute pain in my teeth soon after I removed the strips from my teeth. I didn't know right away that the Crest strips were the culprit and was blaming the citrus flavor mouthwash that I used in the morning. I didn't use the strips for a couple of days. By this time I didn't feel good about using these strips in my teeth. Two days later I used the strips on my teeth again. This time soon after I removed the strips from my teeth I got the most severe pain in my teeth. I took four painkillers and still the pain didn't subside. I couldn't sleep properly due to the acute sensitivity in my teeth. Fortunately it was the Saturday night and I could sleep the next day.
I will never use these kinds of strips again. It was the worst feeling I felt in my teeth.

Crest "White Strips Advanced Seal" come in boxes of 14 strips to be used over a period of 2 weeks.
By no means is this some miracle product that will make your teeth pearly white, but the effects are noticeable. The change in whiteness was most noticeable during the first three days of use, but it seemed to slow down after that.
The strips are pretty inexpensive and somewhat effective for the price. Applying the strips is quite simple as it just requires a simple folding of the strip around the front teeth. After using the product for the first time I found that there was a slight discomfort and increased sensitivity in my teeth where the whiting strip was placed. However, after continuing the usage of the whitening strips I found that the pain eventually disappeared (around the 7th day of using the product) and the sensitivity was also gone.
I'd give the product a 3/5 for effectiveness, 2/5 for comfortableness and a 5/5 for ease of application with an overall score of 3/5.

I've used Crest White Strips about 5-6 years ago when they were pretty new and they worked fabulous! My teeth were so white they would glow in a black light and I loved it. Now that its been a while (about 5 years) since I've used them I realized my teeth weren't very white anymore and I was no longer getting any compliments, so I knew it was time to do them again.
Last night was day 5 of using the new 3D ones and there was no change at all except for my gums hurting so much! I was thinking omg maybe I've ruined my teeth cuz they were so white before and they can't get white again. So I did some research and apparently the new 3D ones aren't working for many people. I actually had a few extra old ones left over, so today I put the old ones (from a couple years ago) on just to see if they would make a difference. HOLY CRAP! They instantly turned my teeth whiter and they even cover most of my smile where as the new 3D ones only cover like 4 teeth. So overall, these new 3d ones suck and do not work.. try and find the older ones!

While other adds for Crest 3D White Advanced Vivid Whitestrips from different sellers count upper strips and lower strips as 1 each, this seller labels it as 2. So when it says 28 count in the title it means 14 upper strips and 14 lower strips, not 28 uses total.
I thought I was getting a bargain but I ended up spending more because I could have gotten the same pack of 14 uses for about $10.00 less from a different seller on Amazon. Oh well, I advise reading the count more carefully and doubt they will accept my request for a return.
