I can't say I have any patience, I'm not one to start something and stick with it however after buying the advanced seal strips I couldn't stop using them. I found myself looking forward to getting ready in the morning. I pop them in as I am preparing for work and by the time I'm walking out the door their ready to come out. It's a perfectly doable habit to get into. It's worth it's weight in gold! Would recommend to anyone.
Only downside is I have sensitive teeth so once in a while I get tooth pain during the day however with my sensodyne that should go away.

Well i just bought the Advanced Vivid Whitestips and i see the dramatic change and its only been 3 days, but im curious if they will get whiter or is it the whitest it will get. Although, i do think that the price to buy these whitestrips is a little too high. I have also recommended this product to my friend and she said that she'll try it out. The only thing that i think that should be improved about the whitestrips is that the bottom strip should be longer. :) (Posted on 29/07/2011)

I used a whole box of these, but I suppose halfway thru I saw full results. I'm 26 and have always had yellowish teeth... being a blonde, I was always so self conscious because my teeth looked almost the same color as my hair! I've tried whitening before with trays, and it KILLED my teeth (or nerves) after only 5 min of having them in... the whitestrips gave me ZERO pain and amazing results! I was so happy with this product that I just picked up the Professional Effects today to see if I can get them "white white." I literally went from grayish-yellow to off white with Adv. Vivid. Totally satisfied! (Posted on 27/07/2011)

I purchased the strips after a friend recommended them to me. I was a little skeptical and price was a little high but purchased anyways to see if they would work! These are the first whitening strips I have ever used and I will most definitely tell EVERYONE I know about them!!! RESULTS are UNBELIEVABLE!!! I'm only on day 8 and the RESULTS are AMAZING!!! Other reviews say bottom strip is too small, it is a little small! Read another review on someone having problems getting the strips off what I do is use tweezers to help get a grip on them and they come right off! BEST BEST BEST product BY FAR!!!! Want WHITER teeth go buy this PRODUCT!!!! (Posted on 20/07/2011)

Until now these strips are the best,but please changed the bottom strip-is sooo small and because of that whitening is not finished.
Thank you. (Posted on 19/07/2011)

The product deliver everything it promises. It love the fact that life goes on while you are whiteneing. I tried Crest Pro strips after using this product and I was very unhappy. The strip did not stick nearly as well and I could do almost nothing while wearing them. Usually, they did not stay in place unless I kept my mouth set in one position for the entire 30 minutes. I used 3 packets of the strips and I am not off to buy more of the advanced seal version - much better! (Posted on 16/07/2011)

Think the Advanced Seal Whitestrips are the best I have used. Do everything they promise. The big problem for me is that the strip for the bottom teeth does not peel off of the backing easily. No matter how careful I am at least half the time the strip comes off but still has the backing attached. It is really hard to separate the strip from the backing when it is "punched" out of the backing sheet. This problem should be checked as it is not cost effect to lose some of the bottom strips because of this problem. (Posted on 15/07/2011)

The new advanced seal white strips are the best so far..
(I've tried them all)
My only complaint is that the bottom strip is Too Small. (Posted on 14/07/2011)

I've used other strips in the past, but my teeth have never been as white - and I still have 4 strips left. These strips stay in place for the entire 30 minutes and do not leave an aftertaste. I'll never consider using anything else!!! (Posted on 10/07/2011)

This is the first time I have used the advanced seal and I cannot believe the difference in the adhesive. I loved the other products especially for the whiteneing but more than likely will continue to purchase the new advanced seal. I have shown my results to several people with my big smile and most have wondered how I have kept such white teeth. Believe me I ell them about your product. there is no need for anyone to go around with yellowing teeth with an array of products that you have available and very simple to use. Thanks for such a great product and I will continue using your whitiners in the future. (Posted on 10/07/2011)

Im 60 now and my teeth started getting darker and darker over the last 10 years. Ive tried everything that is out there. Advanced Seal is the only product that did the job and did it with no effort on my part. No trays to boil, no gooo to put in them and it didnt burn my gums. This is the best whitening product on the shelf. My teeth are nice and white and I reccommend it to everyone. Try it, you will see results so fast its amazing. Great Product !!!! (Posted on 09/07/2011)

these strips are amazing. they whitened my teeth and now i get compliments all the time on my great smile. the newer version...advanced....adheres great! 10x better then the other ones. i would def. recommend this and will buy again if my teeth are looking anything but bright again. one ify part if this product was the price. ouch! specially in this economy. but yet it is cheaper than going to a dentist. just hope they make it cheaper one day!!! all around great product. love it. purely amazing (Posted on 06/07/2011)

At 60 years of age I decided to get braces. After braces I wanted to whiten my teeth just once. I already had white teeth but with age they weren't quite as white as before. I tried a brand other than Crest . What a mess. Since I discovered Crest Advanced Seal there will be no others! This is the best system. Extremely easy to use, my gums didn't suffer, and my smile certainly seems whiter. Thanks Crest for another great product. (Posted on 05/07/2011)

I used the strips two times a day and five days in i saw a dramatic difference in my smile. Before going to the dentist, you should at least try these first. They might end up saving you a ton of money. The only downside is that the bottom strip isn't long enough but the product does deliver. TRY THEM!!! (Posted on 04/07/2011)

This is the best product i have used for whitening....i saw results the first day....and i now have confidence in smiling...this is the best product because it really sticks to your mouth u actually have to pull the strip off your mouth it doesnt just come off (Posted on 26/06/2011)

Crest whitestrips advanced seal is absolutely amazing. INSTANT change in my smile..WAYY faster than premium and classic. However, when I opened the first pack, I thought I got a stale/expired one. I had no idea what to expect and here the instructions are saying "gel". There's no "gel" on the strip..Just a sticker like material. I panicked a bit when I tried to take them off and it was stuck beyond stuck on my teeth.
on the PLUS side. ::
AMAZING results and very fast. I can't even begin to describe how fast they came. VERY well worth your money!
(Posted on 23/06/2011)

I had just gotten my braces of a few days before I started to use Crest Whitestrips and I saw results within two days of using the product. I now have people coming up to me and telling me how pretty my smile is and how white my teeth are. I would recommend this product to anyone, the whitestrips definetly boosted my confidence! (Posted on 21/06/2011)

Love the product. Well worth the money ( and it's very affordable )...you'll see noticeable results within the first few days...will continue to use twice a year. Highly recommend it. (Posted on 20/06/2011)

I was pleasantly surprised by this product. It was easy, fast and above all it worked. A pleasant after taste and good results. It is a bit expensive but still less than going to the dentist for a whitening. It worked well at home and I do recommend it. (Posted on 19/06/2011)

I love this product. It has made my teeth so white and bright. WOW (Posted on 17/06/2011)

I have used Crest Advanced only once and just within one day I noticed a huge difference in my teeth. My teeth were whiter and shinnier. I felt the urge to continuously smile. What I also loved about it was how easy it was to put them on, how it stayed on my teeth and how easy it was to take them off. The classic whitening is messier and does not stick as well therefore, I am more impressed with the advanced whitening. The only downer for the advanced whitenning is the price, which I cannot fit into my budget at this time. Overall, the product is great!! (Posted on 15/06/2011)

I really liked using this product. It was easy to use and stayed on well. People didn't even notice! I had no problem going about my day while these stayed on and did their job. Great product! (Posted on 08/06/2011)

Crest Whitestripes Advanced Seal is the best whitening product I have ever used!!!!
I skeptically put it on and thought it would be just like every other whitening strip I have ever used, But just like it advertises it stays in place,even when you drink something with them on!!!! My teeth are also whiter which made me want to smile alot more. They were sooo easy to use and stayed in place.They were definitely worth the money. (Posted on 07/06/2011)

Better than whitening products than the dentist has (Posted on 05/06/2011)

Much easier to use than other white strips. To soon to see improvement. (Posted on 05/06/2011)

Ill have to agree with other people this product is really good, except for the lower strip it will only cover 4 of my bottom teeth, why is it not the same length as the top one??? I wouldn’t buy them again unless i know they have changed the lower strip... (Posted on 04/06/2011)

Of the 14 strips in the Advance Seal box, three (3) of the lower strips would not adhere to my teeth! After one try- strip is pretty much useless. Luckily I had some of the Professional lower strips leftover from a previous purchase. I did like the 'advance seal' concept...felt I could keep on task without worrying that strips had moved. (Posted on 02/06/2011)

I purchased my first box and the results were awesome, just after the one day!! So Quick and Easy to use!!
Definitely visibly whiter teeth!!! LOVE THIS PRODUCT!!!! (Posted on 02/06/2011)

I recently just turned 18... i've always had nice teeth and wanted to finally whiten them so i decided to go with crest whitestrips. I noticed effects after the 2nd day and have had very little sensitivity only right after i take them off and drink cold things. The only con is the lower strip is a little too small and only covers the front four teeth. (Posted on 01/06/2011)

Wow!!!!!!!!!!!!!!!!!!! It's true guys..I have tried various other brands and got bored with them. I think I will stick with these. I am a former smoker and I really wanted to whiten my smile. The first time I used this product, it whitened my teeth by at least three shades. Yes, I said three shades. I did have a little sensitivity, but it subsided within 24 hrs. One of my friends told me to put brace wax on the edges of my teeth and it will stop the sensitivity. I will try that as my daughter just got her braces off and we have plenty of it around. Anyway, I can't wait to see what my smile looks like after 14 days! (Posted on 01/06/2011)

Well, overall, the strips perform just as noted on the pkg. The manufacturer DOES NEED to increase the bottom strip size left to right wise. The bottom strip at this point BARELY covers 4 teeth. I can not see any reason other than making a new punch die that this should not be taken care of---plently of space to do this without increasing the material needed to sell the product. (Posted on 28/05/2011)

Ok let alone the negative feedback Ive Read.
Before i put them on my teeth had a yellow look. I put this product on and followed the directions i put them on for 35 Minutes even though it says 30 I gave it an extra 5 Minutes. When i took the Strips off my teeth were very white. This is the first time I ever used a Whitestrip product let alone i couldnt believe my teeth were that white. If some of you guys read the directions and followed them Im sure the product will work. Some products work for some people for some it doesnt.
I would recommend this to someone along with this Crest Vivid White Fluoride toothpaste after I took the strips off I used this toothpaste and my teeth look whiter than ive ever seen them in my whole life!! (Posted on 27/05/2011)

I have found the strips too small for the bottom teeth and both are not wide enough. I do like the seal it has for staying on your teeth, however, it is a little hard to peel off. I have used the Pro Effects and those seem to be the right size. Hopefully, Crest will improve the size soon. (Posted on 27/05/2011)

I am extremely pleased with the better seal and hold of the Advanced Seal version of WhiteStrips. I have used WhiteStrips for - pretty much since they have been on the market...
The only thing I think I would change if I could would be to make them as potent as the Professional strength version of the original WhiteStrips. That would be an ace in the hole!
(Posted on 26/05/2011)

Really works great. They stick so much better than the old kind. Just wish you would make the lower strip longer. (Posted on 25/05/2011)

The advance seal is soooo much better than your first crest product. They stay on my teeth and actually are hassel free. Thanks for making a better product!!!!! (Posted on 25/05/2011)

The strips do stick better, and I did see results, I think they are good for people who"s teeth are a little dicolored. But I thought the lower strips are extremely small .
I think I'll stick to the less expensive one's (Posted on 25/05/2011)

I have used Crest Whitestrips for years with excellent results! I recently purchased the new Advanced Seal and was disappointed at how short the lower strip is. It only covers six teeth completely. It is much shorter than the daily whitning lower strip. (Posted on 24/05/2011)

Advanced Seal is a great improvement over the older versions. Easy to apply and they don't slide around like the old ones. I've only had one instance where the lower strip wouldn't adhere. I'd have given them 5 stars except for the fact that they are pretty pricey.
I could only suggest one minor improvement. I occasionally have to fumble a bit to know which side is which. I"d print something on the strip backing to indicate which is the "peel" side. If you do this, then I'd also add a small vertical line in the center of each strip, so you can more easily center them on your teeth when you apply them.
Otherwise, they work as advertised.
(Posted on 24/05/2011)

Crest Whitestrips Advence Seal are my favorite.
It is so easy to use and no uncomfortable gel taste in your mouth. You can really drink water with the strips in your mouth.
Only one disadvantage - both strips should have been a little bit longer to cover one more tooth. (Posted on 24/05/2011)

This is a great product, but the bottom seal does not stay on. I have used 7 strips and 5 out of the 7 bottom ones didn't stay on for even 1 minute. And the bottom strip should be longer. It is way too short. (Posted on 23/05/2011)

I am using my first advanced seal kit. I am fairly pleased. I will buy them again. I do find that the strips stick better. However, I am having a problem getting the bottom strips to stick. The top ones are working great. The bottom ones, I have had to throw out several in the pack, after attempting to get them to stay on. This is frustrating , of course after paying money for these. I only have four more days of strips left to use on this pack, and have thrown out about 4 bottom strips. I am hoping to have better luck with the bottom strips on the next pack I buy. (Posted on 21/05/2011)

I have tried all the Crest whitestrips and this one I like the best.
It adheres to your teeth and feels comfortable. You don't have to worry about the strips slipping off and It did a great job whitening my teeth. I did see a difference in 3 days. It also did not make my teeth sensitive as the other strips did.
The reason I only gave the product 4 stars is because I think the lower strip is too short. Make the lower strip longer and you'll have an excellent product. (Posted on 21/05/2011)

The top strip is the perfet length but the bottom strip does not cover all eight of my teeth that show when I smile. Maybe you could make the strip a little longer.
Thank you!
(Posted on 20/05/2011)

The strips adhere to teeth neatly. You feel comfortable wearing them. I used to dislike the other "older verion" whitestrips because they kept sliding around. These new "advanced" strips solve the "slippery" problem perfectly. Now I actually prefer wearing these advanced Crest whitestrips to wearing the dissolving Listerine strips which give a bitter hydroperoxide taste. Don't know how Crest do it, but with these advanced strips, there is no peroxide taste at all...and the teeth do get whiter noticeably only after 3 or 4 times of wearing.
The only thing that makes me hold back one star in the rating is that these advanced strips are too small. They barely cover the front teeth. They would be a lot better if they are longer and wider to cover more teeth on the sides and to remove the stain in the back of the teeth. Not sure if the cost is the reason why P&G makes these strips so tiny, but I think if they revise the size and upsell the bigger size a bit more, they still can definitely sell to those who seriously care about their smiles!

This iis a super whitening method that is easy to apply and it works great.It does not interfear with eveyday life.I don't like going to dentist,so this method is safe,affordable,and it worrks ! Thanks Crest ! (Posted on 18/05/2011)

I liked the new packaging of this product but did not like the new application of the strips because it did not cover the whole tooth in between the grooves to whiten them as well. (Posted on 17/05/2011)

I have used various Crest White strips in the past and all with great results. I especially love the new advanced seal white strips except for one thing. The bottom strip is Too Small. It only covers 4-5 teeth. I compared it with the other strips and there is a noticable difference in the size. I personally would like to whiten all of my teeth with your product not just a few. Otherwise, I love the sealing bond with the new strips. They don't move around. (Posted on 16/05/2011)

I have used Crest whitestrips a couple of times, but when I opened the package of my current box, I was disappointed. The bottom strip is so small! Other strips have been much longer to actually cover all of the teeth on the bottom. I don't know why Crest decided to go with these smaller strips, but it is unfortunate.
The seal of these strips is pretty good, though. And they work... just make sure you aren't going too bright against your old shade- because these strips are so small, people will be able to tell you used them! (Posted on 15/05/2011)

The product stays in place and is effective, but the strip for the lower teeth is entirely too small. It only whitens the very front teeth leaving the others your original color. I don't understand this as the old versions were better in size. If it were not for that major disappointment then I would give it 5 stars all the way. (Posted on 13/05/2011)

I thought that they were working well when I looked in the mirror, but then I looked in the mirror against my white shirt I was wearing and was not impressed at all. The bottome strip is way too small and does not peel off easily and sometimes I had to throw away the entire part and get a new one. Not very economical considering the price. (Posted on 13/05/2011)

Although I have had good results in the whitening aspect, as with the classic strips, I find the lower strip is far too short to cover the entire row of teeth.
To get coverage, one time I will apply to the right side, then alternately to the left side. The result is that my lower teeth furthest from centre only receive treatment every second time. The Advanced seals although more money, are actually shorter than the Classic, which are too short as well.
I would appreciate an email back if it would be possible to make the lower strip longer....same length as upper would be ideal.
As a long time user of whitestrips, I am puzzled as to why the lower strip is so short.
Otherwise, great product.
(Posted on 09/05/2011)

I like the Advanced seals but I feel the lower strips are to small and the tops could be a bit longer as well. I guess if you have a small smile then there great, But I have a large as life smile and I have been a fan of the Crest White strips for a very long time. A bit pricy but what else is new when it comes to something better.. You want it? You will pay the price. I'd like it as i'm sure other would to if they made kits for the whole mouth with say small,med,large as well.
That's it in a nut shell.. hope they listen to customer over at Crest. (Posted on 08/05/2011)

After i used the strips i noticed that my teeth are getting whiter, however the bottom row of teeth is a problem. The top "long" strip covers most of the top row of teeth. But the bottom strip only covers about "4 teeth" only because the strip is sooooooo short. As a result you have extra teeth on the front heading towards the back teeth, on both sides that are NOW yellow compared to your "NEW" white teeth. for this much money they should have ALL VISIBLE TEETH GET WHITE. Other wise you'll look nasty with 2 or 3 yellow teeth in bottom row. It does whiten from what i can see. BUT THEY NEED TO DO BETTER WHEN IT COMES DOWN TO THE CONSTRUCTION OF THE STRIPS. (Posted on 04/05/2011)

I do think the new advance seal product is better than the original, but I could not get the lower to stick or stay in place. (Posted on 02/05/2011)

I love the way the strips cling to your teeth. That they leave no film on your teeth is fantastic. I am a smoker and tea drinker and these whitestrips have definitely made a world of difference. After the 3rd use I was no longer self conscious of my smile. I have only one suggestion to improve this product. That the bottom strip could be bigger, it only covers basically 4 teeth and when you really smile you show at least 6 teeth and I don't consider my smile a big one. Over all great product. Would just like bottom strip to cover more teeth even if cost a little more money. Would have given straight 5 stars except for bottom strip. (Posted on 01/05/2011)

I have used Crest premium and Crest Pro Effects in the past and have been very pleased with both, so when the 3 D strips came out, I tried them. I was very unhappy with the results, they did not work as well as the pro effects. I could not tell much of a difference after using the entire box. (Posted on 30/04/2011)
