I got selected to review this product from ChickAdvisor, thanks again ladies ! :)

I received the package and instantly ran upstairs, ripped open the box and pulled out one of the foil packages. Either the instructions are very vague or I lack common sense because I put them on the wrong way the first time around. I realized halfway through I had them on incorrectly and by then they were glued to my teeth. After about 1.5 hours I had to remove them I had sharp pains shooting through my teeth from the gum line down, ouch! I had a little bit of a hard time removing them which was stated may happen in the pamphlet that came with it. I found it you pulled the tab from behind the teeth first it was a lot easier to remove the whole strip.

I found after the first use my teeth were slightly whiter. My boyfriend even noticed and he rarely notices things like that. They did leave a little bit of white spots behind on my teeth but that disappeared after a few hours. Later on that night my teeth were so sensitive I could barely even breath in because once the air hit my teeth those sharp pains were back. I also found I had a hard time eating certain things cause my teeth felt as if they were rubber for a few hours.

The next day I tried them again. I made sure I put them on the correct way this time and after about 30 minutes the shooting pain came back, I removed them immediately. I repeated the next day and so on for 5 days straight. I found if I only left them on for about 30-60 minutes, my teeth weren't as sensitive after yet I still achieved a whiter smile. I still have 2 more strips left. I found this product worked great, a lot better than I even expected. I have a much brighter smile, that quite a few people have noticed. I would try these again but I would try to do them every other day and not for the whole 2 hours of time. I would also recommend these to anyone looking for a quick way to whiten without dropping lost of $$$.

I've been wanting to get my teeth whitened for a while now. I was asking around and getting it done professionally is around $500?!??! I was so happy to be selected to review this product because I was able to save a ton of money. Also, I have heard plentiful times that this works just as effectively as getting it done professionally. Even my own dentist said so!

Anyways, after the first use I noticed a difference in my teeth. The first use was not noticeable from other people but I could definitely see a subtle difference. It was whiter already. Also, I was worried that it would be hard to keep the strips on for 2 hours but the advanced seal worked wonderfully. I was able to talk and even drink water with it on. It did not bother me as much as what I had originally thought. It's great especially if you decide to take a nap during the day while having this on so that by the time you wake up your two hour is done.

The only downfall I find with the strips is the sensitivity that it caused my teeth. Even after the first use, my teeth became extremely painful. Even if I keep my mouth closed, my teeth continued to hurt. I was not able to use this daily straight for 7 days, but using it once every few days was bareable and that's what I did. Even though my teeth became sensitive after for about 10 hours, it is totally worth it. I would def buy this product again and again.

First of all, let me say that this product works. I noticed after the first use that my teeth were whiter. Of course, my teeth aren't really stained horribly either, but I could still see improvement. On the first use, I experienced a little bit of lower teeth sensitivity, but it faded within a couple of hours.

But it got worse. Last night I used the sixth in the package and the effects of the sensitivity for my lower teeth has YET to wear off. I took the strips off nearly 12 hours ago and my bottom row still hurts. I can't even speak because the feeling of air rolling over my teeth makes it hurt even worse. It should be noted that I have NEVER really had issues with tooth sensitivity before (I say "really" because if I'm eating ice cream and I try to use my front teeth it stings a bit, but that's it).

I use whitening strips once a year. Last year I used Crest as well, but it was a lower grade on the intensity level and I didn't have any problems at all. Of course, I didn't see such great results either. There WERE results, mind, just not as...well..."intense" as these Intensive Professional Effects.

All in all, the product works, but you might have some pain WHILE it works. Then again, Beauty Is Pain.

i do like the whitestrips! but it was hard to put on my teeth as my teeth are not perfectly straight. but i do like the results i got. even tho it took awhile to put on my teeth the right way. i would recommed it. if you were down with a lil extra work to put on.

I was excited to receive the Crest 3D White Whitestrips Intensive Professional Effects for review. This kit contained 7 strips for top and bottom front teeth. I read the instructions and nowhere did it mention if this product was meant to use for 7 consecutive days (back to back). Since this is the intensive version, you have to keep the strips on your teeth for 2 hours. That proved to be quite long for me. Your mouth automatically produces extra saliva and it was hard not to have my tongue touch the strips or have saliva on them. I tried as best I could to keep my tongue in the back of my mouth and tried not to swallow too much. The first day was ok. During the time the strips were on my teeth, there was just barely a hint of taste. It felt comfortable enough. I started noticing a slight tingling sensation about 1 hour into the process. After removing the strips I rinsed my mouth. It should probably state somewhere in the instructions not to try to eat or drink anything hot or cold after a treatment. I found I had an issue with drinking water. Second day, I repeated the process and got the same tingling sensation about 1 hour into it but nothing too too unpleasant. After the second treatment, my teeth remained sensitive for hours. I could not drink water or coffee without it being very uncomfortable. I decided it best to discontinue using the product for a 3rd day in a row. I understand it states on the box that sensitivity is normal and temporary due to the intensive nature of the treatment, however it proved to be too uncomfortable to continue using. I am sure if I would had continued a 3rd treatment, I would have been in serious pain afterwards. I would not buy this product for myself due to teeth sensitivity nor would recommend it for anything who has sensitivity issues.

I was so very excited to receive Crest 3D White Whitestrips in the mail and I was so happy that I was chosen with others to review it from the chick advisor club. I just couldnt wait to test it out. I was surprised how easy the strips were to place on my teeth and how smooth it felt. So easy,just peels off nice and smooth and when i rubbed my tongue across my teeth,it felt like i just went to the dentist. I noticed after 2 days the change of color to my teeth.I drink alot of coffee and my teeth had light yellow stains...just enough to make me not want to show my teeth off....now,i can give a big smile and feel like everyone is looking at me. Thank you ChickAdvisor for this awesome package, i will surely reccomend this product to my friends & family xo

I recieved the Crest® 3D White Whitestrips Intensive Professional Effects, free to test as part of the chick advisor product review club. I was extremely excited to try this product upon recieving it. The first time i used it I noticed a major difference in my teeth colour. Although the bottom strip, did not stay on as well as I thought it would. I did experience a bit of tooth sensitivity, but mostly on my bottom teeth. After the fifth day of using this product, I am absolutly floored! My teeth are super white and feel amazingly clean. I will definatly be buying this product again, and will definatly be recommending it to my family and friends.

I got to review this product through ChickAdvisor's product review club (:

When i first received this in the mail, I was so excited to test it out, and tried it first that very day. Even after just one use, I could notice that my teeth were definitely whiter than before. Not extremely whiter, but definitely whiter.

Now, almost having used up the entire box, my friends and family have all been noticing my whiter teeth. My moderately yellow teeth have been changed to a very pale/light yellow. Many people have been complimenting my teeth lately, which is definitely a great sign.

The only downside to this product is that it makes your teeth a little more sensitive than usual, especially when you're outside and the wind starts to pick up. Nothing that a little sensodine cant fix, but other than that there are truly no down-sides to this product! I definitely would recommend this product to anyone who wishes to whiten their teeth in 7 days. For the professional quality and results this product gives, the price tag is definitely worth it!

I was so very excited to receive Crest 3D White Whitestrips in the mail and so happy that I was chosen with others to review it. The packaging is so cool,like a triangle type shape at the corners of the box,this would catch my eye in any store. Then I just couldnt wait to test it out. I was surprised how easy the strips were to place on my teeth and how smooth it felt. And I thought,I would watch a movie on TV and by the time the movie was done,i could remove the strips. So easy,just peels off nice and smooth and when i rubbed my tongue across my teeth,it felt like i just went to the dentist. I noticed after 2 days the change of color to my teeth.I drink allot of tea and my teeth had light yellow stains...just enough to make me not want to show my teeth off....now,i can give a big smile and feel like everyone is looking at me like i am a movie star. Thank you ChickAdvisor for this awesome package,i surely reccomend it and now i will be looking in the stores for the next time i want to whiten my teeth.

I was lucky enough to receive these items as part of the Product Review Club. The pack came with 1 small set of instructions and 7 packs.

The instructions I personally found lacking, and confusing. The instructions were more of a generic set of instructions they used with every type of product so you need to read them carefully to make sure you are following the correct instructions!

You open the sachet, which contains 2 small plastic rectangles stuck onto a clear sheet, one for your top and one for your bottom teeth, apply to unbrushed teeth. These strips are very adhesive and stick onto your teeth very well, press along them with your finger to guarantee a tight stick. For me, this part was easy they stuck very well, and fit very easy!

The bad part however, was the drooling. Almost immediately, I began drooling a lot. So much so it was actually dripping out of my mouth, I ended up sitting with a towel under my chin. But hats off to the product, it managed to hang in there through my river of saliva. I managed to keep it on through the 2 hours, and I finally peeled it off. It was a big tough to pull off, but it came off easily once I got it going. A little bit of residue was left on my teeth, so I gave them a wet brush to remove it.

Instantly, my teeth felt smooth, and clean! AMAZING!

Sadly though, that night whilst I was asleep, I woke up to severe and shooting pain down my front teeth, both top and bottom, the pain was so intense it woke me up. I got up took some pain killers, thinking nothing of it, then went back to sleep.

The next day, I applied my second set of strips. I managed about 1 hour and 10 minutes before the shooting pain started again. I applied them exactly the same way as the day before, but this time the pain was unbearable. I took the strips off. The pain stayed with me for about 2 - 3 hours, and then again in the middle of the night I had a shooting pain waking me up.

On the plus side, once again, my teeth were super clean, and looked a little bit lighter.

After 2 nights of waking up with intense tooth pain, I decided these strips were not worth it for me. I read the box, and they mentioned some pain would occur but it would only be temporary, and they said the strips do not in any way damage your teeth. I do trust this explanation, and I do think this product really works, but pain especially in my teeth worries me.

I am worried about permanently damaging my teeth, or making them overly sensitive, as much as I want white teeth I really cannot justify the pain. If the pain only lasted during the application I would reconsider, but being woken up 2 nights in a row with shooting pain is a problem which is interfering with my life.

In short, the technology behind these is great, the product works well as directed, but the side effects are a deal breaker for me. My teeth are a normal off white colour, a bit yellowy and I have always dreamed of TV White teeth. This product would probably get me there, but the risk of havign constantly sensitive teeth is not worth the reward, in my opinion. I have been to the dentist many times, my teeth are in good condition, and according to her I do not have sensitive teeth or gums, so the fact I am having pain worries me even more.
