Crest Whitestrips Advanced Seal

I'm writing this after using the Crest Advanced Seal twice in one day . I LOVE IT . I see the results just after using it the second time . The first time I used it I only got two pangs of sesitivity for a few seconds and that's it . I see people here complaining that it hurts so bad and I think they're being ridiculous . What do you expect ? It doesn't slip at all as promised . I can't wait to see the results in 10 days !

PAIN PAIN PAIN... yes they work but after 2 days i was in the worst pain EVER. i do NOT have sensitive teeth but NOW I DO. they ruined my teeth.


WORST PAIN . not worth it for white teeth.

Product did not work at all. I followed directions EAXCTLy and see no difference what so ever.

It olny got my teeth a few shades whiter, the bottom one is not sticky at all, barely fits over my teeth, have so much sensitivity on the bottom teeth
would never recomend these at all.

I have been using this product for the past 3 days and I can definitely see the difference. The best part is the no-slip strips and you can still drink a beverage while using them. The strips are not very difficult to remove either. I have noticed some tooth sensitivity, but nothing that I cannot tolerate. I would say that they are alittle pricey.....but I found some coupons which helped. I would recommend this product as it does exactly what it says.....I am definitely one satisfied customer.

I used this - two applications in the first day a couple hours apart and I saw results the next morning. I mean big results. I still have 18 packs so I really think my teeth will be blinging by the time I use them all- that is if I even need te, all. These work well! Now I should mention that my teeth were not very yellow at all- more like a dull white but now after one day they look like a stark white! Good luck.

Love love loveeeee thiss! first time ever whitening! Seriously after about 1 day literally I could see the difference! less of a yellow tint already! But experiencing horrible amounts of sensativity atm:( mayb because i feel asleep in them for two hours! Anyway hope to see even better results by the end of it:D

I just bought this product a few days ago. Im only on my third day but i already see the difference. My teeth werent really yellow to begin with but they are making my teeth really white. The only negative is that i put my strips on at night and i couldnt sleep because of all the pain and it lasted all the next day but i realized it was because i put them too high up on my gums! great product! =]

Good results but... bottom strip not long enough, bottom strip will not stay in place on teeth, top strip sticks too well - hard to remove. Found them for a great price at Big Lots. Will be trying another formula next time.

I'm only on my fourth day, but im already seeing improvement. I experienced very very slight sensitivity on s few of my bottom teeth, but it went away within hours. I am very pleased. THe only problem is these strips are hella expensive! but its okay because they work pretty well

I have used advanced strips for quite a while now. when I used them this time they would not adhere to the teeth. When I opened the package they were not stuck on to the plastic paper. They were useless. I'm going to change brands. Too expensive for this to happen. yours truly, Lavinia Syvertson. I was satisfied until this happened

Pain. I got a sample a long time ago and hadn't tried it until now. stuck great but bottom strips are small like everyong else is saying. took them off, brushed my teeth to get the extra gel off and went to bed. woke up in the middle of the night in pain. they just plain hurt. couldn't sleep for a long time because they hurt so bad. they didn't hurt today until AFTER I ate. I've used various whitening products in the past with only slight pangs of sensitivity. Nokrvthing like this

I just started using this and trust me it works Great.And people that say it dosent is only because they have really yellow teeth.I feel bad for them.Too bad they dont have semi yellow teeth or it would have worked!!!

This product didn't work for me at all. It's the last day and there's absolutely no difference, the only thing i can see is some white strips on some of my teeth, hopefully it'll disappear after a while cause. I drink a lot of coffee so I wanted a quick fix. Afraid of Zoom and the zingers, this seemed like a nice alternative. I was wrong, a complete 60 bucks rip off

The lower stripes are too short, don't understand why they can't make it longer. It was OK to put on and no sensitivity issues (I used Sensodyne before and thru) but I wouldn't recommend it to anyone.

so i have been using the strips for 7 days and so far no real results; the strips do stick better than others and they dont cause as much saliva build up as the other strips i've used. i havent had any teeth sensitivity either so thats a good thing; i really wish they would have whiten better because i feel this is a waste of 40 dollars

im lo 15 and im going to prom in a few months w/a senior woooo!!!haha so uhm my sis got the normal strips i dont know why because her teeth are super white anyways on to me <333
i had braces first grade to fourth so i thought that i can get away with out brushing my teeth bs my teeth were hecka ugly and the dentist who took them off scrapped to much of my front tooth so now i look like a hill billy with a yellow teeth and a stain there not even straight anymore :l
sooo i bought this product crest advanced seal thing and this is my second day they look clear'er but the stain on my tooth stands out now my brother in law put me on blast for it but idc he has beaver teeth ha >:D.
So so far my bottom teeth are sensitive but hopefully its just today ,i already love this product minus my stain but
hopefully it goes away (:

I already have white teeth but I wanted to try making them even whiter. In one day I did see a difference but there are parts of my teeth that are whiter than the other? It didn't seem right. But my teeth hurt like a bitch. They hurt so much that I can't use them anymore. But it's probably because I wore them when I was sleeping and your supposed to wear them for 30 min.

I have used all Crest White Strip products in the past; I have fairly white teeth from in office procedures. I like to use Crest White Strips to maintain the whiteness between visits and they have ALWAYS worked wonders for myself. I was anxious to use the Advanced Seal because regular strips do tend to move around easily. These definitely are advanced in the sealing process, but lack the ability to make fairly white teeth whiter. I would assume that this product would work on somebody who had a lot of discoloration, but not for somebody who is just looking for that little extra bit of white. The bottom strip looked like what Crest had originally come out with years ago. I was disappointed that they didn't use the bigger strip for the top and bottom like the Premium Strips do. Overall I would not recommend this product for somebody with already white teeth. Compared to the $500.00 spent at the dentist, it is a great price, but inconvenient to have to do 2X per day for multiple days. Hope this helps!

This product worked very well for me. I'm 56 and always took good care of my teeth but againg, smoking, drinking red wine, tea and coffee discoloured my teeth. After using these Crest strips it's as if they're thoroughly clean and thus whiter. Will use them again for sure.
My teeth are indeed a bit more sensitive but I gather that will get better and I'm using products for sensitive teeth for a while.

I loved these whitestrips. They stayed on really well and I did see results in just 3 days..I'll buy them again!... but you probably don't want to wear them while drinking water because they start to fall off

I was so happy that after 3-days I experienced zero sensitivity. Sadly, at the end of 14-days, I did not experience any noticeable whiteness, either. Waste of time and money. 10% peroxide is nothing compared to what dentists use.

The strips work pretty well if you stick to the plan (2 a day, don't brush right before), i have whiter teeth and yes they are a little sensitive at the beginning where cold water is like brain freeze for your teeth. But no major problems with the strips, make sure to wash the gel off your skin (bleaches your skin), and get some toothpaste designed for sensitive teeth. Also, for people saying the bottom strip is too narrow...i think you have it backwards. the bottom strip is actually wider than the top and you'd need some huge bottom teeth for it to not cover them.

I give this product a very low rating. Ive been using them for a few months and I still dont have white teeth. Im very disappointed with it.

Okay, so I've been wanting to try these for a while.
I finally got some and all I have to say is ouch! My bottom teeth
are hurting pretty bad. The strips stick very well to my teeth
which I love. But the bottom strip is too narrow and too short.

I have been using the strips for 3 days now, i had pretty white teeth to begin with and i am already noticing a difference. i probably go through a box of white strips 2 times a year just to whiten my smile. before using the strips i had mildly sensitive teeth, basically they never bothered me unless i ate something cold like icecream and it was bearable just uncomfortable. anyways today is my fourth day and my teeth are soooo sensitive. its ridiculous they hurt if i breath through my mouth smiling. but, for the difference they are making in my smile i am continuing to use them and will be purchasing a tube of sensodyne
