Crest 3d White 2-Hour Express Teeth Whitening Strips 4 Count

()It's a box of four sets of whitening strips. It seems to suggest that this OTC whitening strip finally contains enough concentration to whiten enough in merely 2 hours that the effect will last 3 months, as the box suggests that it's good for a year's supply. Typically over the counter whitening strips doesn't contain nearly high enough concentration of peroxides, that only after multiple and frequent applications will any results start to show. I wonder if this is different.

Application is painless. It doesn't even suggest brushing your teeth first (in fact it recommends that you don't brush your teeth immediately before application). The whitening strips has a relatively thick layer of gel, and the substrate film material is very pliable yet durable. Its purpose is trying to simulate a dental office treatment, where your teeth will be immersed in a tray of (highly concentrated) peroxide gel/mud. It stuck to my teeth with little effort and dexterity. Within minutes, my teeth was engulfed in a bubbly peroxide bath.

Having this on feels a bit strange in the mouth, and I talked like I had a big tongue, but I tried to carry on as normal. It stuck to the teeth very well, despite my biting right over the strips and licking them. The bubbly area also largely stayed put, and little disturbed by saliva and movement of the lips and tongue. Bubbly substance does seep out in the form of thick gooey film(or it's just a mixture of saliva and gel substrate). My teeth felt the effects: I wouldn't call it discomfort, but after 5 minutes I started feeling something is happening to my teeth, though it's very slight (and probably depends on people's sensitivities).

Taking it off after two hours was easy: just rip it off. I deliberately left a few teeth half covered to see if there are any before/after differences. I noticed that many of my teeth developed white marble-like patterns, or probably what the instruction referred to as "white spots". It seems to develop around areas where the teeth's surface may have imperfections and crack lines. It's said to eventually go away and I believe it.

Thus interestingly, while I wasn't expecting much effects, it seems to have done something. Alas, the experimental tooth where I left half uncovered didn't reveal much difference between the treated and untreated area, other than the marble pattern of white lines that formed on the surface of many treated teeth. I probably have deep coloration problems that cannot be treated by surface oxidation through a moderate peroxide concentration? Anyway, in other words, it didn't work all that much for me.

That said, those white marks on my teeth suggests that the strips did contain a decent amount of peroxide concentration to at least show its effects in two hours, which is on the faster end of average home treatment strips. I had my friend try it and it didn't seem to make that much difference for her either, however.

Therefore, while the active ingredient seems to be layered on thicker and more concentrated than average, it still doesn't seem to whiten that much for us. I wonder if more applications will help, but certainly not at only 4 times a year or once every 3 months. It's probably not strong enough to give off that much lasting effect with such infrequent use.

()I'd never used a whitening strip before, so wanted to give 'em a try.I really wanted bright teeth for a client meeting, and my teeth really needed a brightening up.What surprised me was that you don't brush your teeth first. That was counter-intuitive.I stuck in the strips, waited two hours, and saw a slight difference.Not a lot, but some.Well, I was in a hurry.I used another strip four days later, and another a few days after that.That really gave me some great looking teeth. Not blindingly white, but attractive white.

My only complaint is that there's gummy residue remaining on your teeth after removing the strips. I had to pick / wipe it off for a few minutes.

I was happy with the strips. Sure they were supposed to be used over a few months, but I had more immediate needs.I have slightly sensitive teeth, and these did not bother me at all.The strips are a little strange feeling, but they did not effect my speech. There was a Peroxide taste after a few minutes. I had to hold off on eating and drinking for a couple of hours though...

I give 'em a thumbs up!

I have used various at-home teeth whitening strips and gels several times in the past and had also had my teeth whitened professionally once. So when I saw these 2 hr ones, I thought "wow, great--should be really good". I applied the strips and waited 2 hrs. The strips really did stick great and I didn't have as much problem with them moving around that I normally have with whitening strips.

However, when I removed the strips the effect was very slight--not really noticeable at all. But, a few hours later I started having pain in my teeth and I've NEVER, EVER had any tooth sensitivity before. The pain lasted quite a few hours and even though I took 2 Aleeve the pain was still there. Cannot imagine the pain if a person has tooth sensitivity to begin with. I wouldn't advise anyone to buy this product.

These strips made my teeth horribly sensitive. A few hours afterward, my teeth were shooting pain, even when I wasn't drinking or eating anything. I don't normally have sensitive teeth, but if you have even the slightest bit of tooth sensitivity I do not recommend these. The whitening was ok but the pain afterwards....not worth it.

()I regularly use 3D White toothpaste which works, so I have a good general impression of the brand.And so, I was excited to try 3D White Whitestrips which are convenient and affordable professional results.Per the product page these wonderstrips claim:

-To show visible results in 2 hours (the level of whitening will vary)

-To use the same agents used by dentists (whitening peroxide) to whiten teeth

-To be easy to use (simply peel, affix, wait and remove)

-To be easy to maintain (the standard box comes with a year's supply of treatments, and the strips only need to be applied every 3 months).

-To be safe (when used as directed).

I can whole heartedly confirm that these strips ARE easy to use, and cost just a fraction of what you'd pay a dentist.The AdvancedSeal does allow you to talk and fixes on better than any whitestrips I've tried in the past.However, I have to say that after 2 hours my teeth only appeared mildly whiter.I got a second opinion from my spouse who said, "they did look a little better".And so, I am not wildly impressed.Also, the next day, my teeth were noticeably sore.Coincidence?I'm not so sure. The final result isn't worth the emotional letdown, two hours of downtime, and weird aftertaste that lingers for a day or so.
