To sum it up - this product works as advertised.

I used white strips many years ago, and my biggest complaint was the strips slipping all over my teeth (thus making it hard to keep them on for any length of time). This time, there were no issues with that at all :)

The strips made my teeth noticeably whiter after only a couple uses...very impressive.

I was worried about teeth sensitivity, but had no problems with that.

I have already purchased another kit for my husband to try - he's jealous of my awesomely white smile ;)

At first I was wary to try these. I had heard of Crest strips causing tooth sensitivity, the horrible taste and the leftover stuff from the strips. They were effective but a lot of cons to go with the pro.

I sucked it up and tried them out. I found the instructions were too vague on how to use them properly for the best results, ie. before/after brushing, after eating, in the morning/evening etc. Once I figured it all out, they were super easy to apply but I did find myself picking at them a lot. I was very aware of them on my teeth and although they did not hurt or anything, it was slightly irritating. There was a taste but it was rather mild. I waited the full 2 hours the first day and had some sensitivity after but it wasn't too bad and I did notice a difference in shades of my teeth. I also noticed the tip of my tongue was tingling a lot but I figure it was from me picking at my teeth so much.

The second time I tried them, I took them off after about 1hour 40min. I was going out and had to take them off a bit early. I noticed a lot less sensitivity with this slight amount of less time and again noticed my teeth were whiter.

I did the remaining days at the 1hour 40min mark and had no issues at all. My teeth are noticeably whiter and to put it to the test, I didn't tell my husband I was using the strips while he was at work. I told him when I was done with all the boxed and he commented that he had noticed something different with my smile but couldn't pin point it. I notice myself smiling with teeth more since using the strips.

The price for me is a bit out of budget just for teeth whitening, so I probably wouldn't buy it myself. I would happily use them though and recommend to people who can afford it.

I rec'd my kit, I love this stuff, it works. It stays where you apply it, it adhears to the teeth perfectly, and stays put while talking for the entire time. I did find tho, wearing the strip the first time and for two hours, my teeth were so sensitive afterwards, so I did cut the time down by half hour and that seemed to make a difference, but I still got the 'awesome' effect that the 3D Whitestrips are supposed to give you. I would recommend to anyone to purchase this product, and I will be using it again.
Thank you Chick Advisor for giving me the opportunity to try this product out.

I got the email August 30th that I had been selected to participate in the product review club offer for Crest® 3D White White strips Intensive Professional Effects. I was sooo excited as I always wanted to try this but couldn’t bring myself to pay 60 dollars for it. I couldn’t wait to try it. The first day wasn’t so bad. With the Advanced Seal technology, it was a convenient, no-slip whitening treatment. unlike whitening toothpaste i have used in the past i saw a difference after the first day i used it. Even my friends noticed and commented on it. After the 3rd and 4th day though my teeth became sensitive so I skipped a day and then continued treatment. Now I have Perfect pearly whites to make me feel more confident about my smile, and without the hefty price tag from the dentist. I wouldnt recommend it if you have sensitive teeth however if you want the bright white smile this is surely the best way to go

Thank you so much to ChickAdvisor for letting me try and review this product!

I was surprised that these strips cost $70! It's a bit pricey for me but if you compared it to what you pay for a professional whitening, it's a fraction of the cost.

I was very hesitant (but excited) to try this product as I have never use whitening strips before. I heard that they go jelly-like and doesn't stay well on your teeth. However, this was not the case. The whitening strip stayed on for 2 hours without feeling too weird in my mouth. At first, it tasted kind of weird but I got used to it after a few days; it has a minty, plastic-ky taste to it. On a side note, I found the instructions really vague as of which is the upper and lower strip.

Onto the results, I could tell by the first day of using it, my teeth was whiter. Amazing! Just 1 use. However, I did experienced some major sensitivity (sharp pains I would say) possibly because this is the first time using whitening strips. As a result, I use the strips every other day instead of using it daily. For the rests of the application, I deliberately used it a few hours before bedtime so I won't have the sensitivity after I woke up. But I still had mild sensitivity a few hours after I woke up. I would probably buy the strips that are one level lower so that I don't have to put them on for the full 2 hours. Note that there was residue left on my teeth that was quick removed by brushing.

Bottom line: this product works amazingly and delivered on its promises.

I would recommend this product to those who:
- experience very little to mild sensitivity
- wants instant results to a "brighter, whiter smile"

I was lucky enough to received Crest 3D Whitestrips for free from the Product Review Club. I have tried Crest White strips in the past when they first came out with them and they have come a long way! When I first tried the product years ago, they were very effective but I hated the taste and texture of the product when taking the strips off. They also smeared onto my gums while using the product so it wasn't very pleasant.

I was excited to try these as it has been quite a few years and I was curious to see if I would get the same great results without the gooey/messy after effect. I was pleased to see that they did in fact make my teeth noticably whiter and weren't as messy. I don't have tough stains as I'm not a coffee or pop drinker however I love a glass of red wine and the occassional tea.

One thing I did notice about this product and the previous crest strips I've tried is that I do not need to do it for the full term they suggest, the full 7 days. I find they got the job done after a few days which helps for someone who is worried about spending the money for 7 days worth of white strips.

Wearing the product for 2 hours/day can be difficult and time consuming as I wasn't able to talk comfortably in them and my mouth produced a little more saliva than usual. So I wouldn't recommend wearing them to work or on the go as some commercials suggest.

I didn't find my teeth more sensitive than usual, but I didn't eat ice cream or really hot beverages so that might be why.

Altogether, the product is a little pricey but it definately works and I did see improvements. Would I buy them? YES! Like I mentioned earlier, I've used them before and these are new and improved so I would definately use them again when needed. If you're someone who is in the market to whiten your teeth without going to the dentist I would say GO FOR IT! or if you're someone like me who has little staining and wants to brighten up your smile for a vacation/event spend the money and go for it too! You don't need to do the whole treatment time, a few will do and you'll have enough for another few days :)

I received Crest 3D Whitestrips for free from the Product Review Club and was really excited to try them. The product worked really well and the strips were easy to use. I noticed a difference in the shade of my teeth, they were considerably whiter. I would definitely buy this product again .

I was very fortunate to be selected to review this product for ChickAdvisor. The RRP of $70 is rather steep, but after seeing the results, I do feel that it is justifiable as a twice yearly treatment. The strips are quite easy to use, and adhere well to the surface of the teeth for the 2 hr duration that it needs to be left on. I highly recommend NOT eating or drinking with the strips in place. The first few days that I used the product, I felt some sensitivity, and did not leave the strips on for the full two hours. For the last four days of the full week trial, I was able to keep them on for the full two hours and the sensitivity had decreased quite a bit. Even though I didn't have them on for the entire time at the beginning, the product still did what it says it would do, which is to whiten your teeth. Now, my teeth did not go to the shade of blinding, pure white that you see on the veneers of movie stars, but there was definitely an improvement, so that overall, my teeth did not look as dull and "yellow" as they did before. I also like that very clean feeling that I get on my teeth after the strips come off.
I had already recommended this to my girl friends, but not as something that should be used regularly. First, the price tag is quite high. Secondly, having to leave the strips on for 14 hours over a week is a bit inconvenient. I also don't think that this is appropriate for people who have very sensitive teeth or gum issues. But if your teeth and gums can handle it, then it's worthwhile to treat your teeth to this every 6 months or so to maintain that bright smile.

I've purchased whitening strips before but never the advanced seal. I highly recommend it! I noticed a difference after the first application. It really is like getting your teeth professionally whitened. You do tend to feel some sensitivity after the entire treatment but the sensitivity does go away and you are left with a beautiful sparkling smile! It is pricey to purchase it but completely worth it.

I've used Whitestrips for quite some time, and tend to buy a box every two years. While they are pricey, they do offer significant whitening for a price far below that you would pay at a dental office. I was provided a box to review by Chick Advisor, and this was my first time trying the Intensive Professional Effects. I love the Advanced Seal technology, and will never go back to the regular Whitestrips. These ones stuck tight for the entire two hours, and did not leave a goopy mess all over my teeth or slide around.

I had my front teeth filed years ago, and do get sharp sensitivities when whitening. I did get some unpleasant sensation about 20 minutes in which faded away, and chose to use the strips every second day which helped.

Finding two hours to use the strips was also difficult - I tried wearing them while on the elliptical, but my mouth produces a lot of extra saliva when wearing Whitestrips so it wasn't really practical. I ended up using them in the evening, with the only downside being that I couldn't drink tea during that two hour period. I found I was easily able to sip water with a straw while using the Whitestrips.

After 12 days of whitening (7 two hour applications) my teeth are several shades whiter, and I have gotten compliments. I haven't experienced any lasting sensitivity. In the future I would purchase the next level of Whitestrips down, so I could use the Advanced Seal but not have to apply the strips for two hours daily.

If you need white teeth in a hurry and do not experience sensitivity, I would recommend this product. If you have more than 7 days, I would recommend another Crest Whitestrips product with less intense effects.
