I'm sensitive to common tooth stripes so i switched to this product several months ago. Honestly i didn't expect too much. I only applied to 8 of my teeth daily, which took me 5 seconds a day. Today when i looked at my teeth in the mirror, those 8 teeth are so distinct, they are in a different color from the rest of my teeth, much whiter. Amazing product, i will continue use it lifetime.

I love Paula and her products! I have given pretty much all of her products five stars, and many of her products are my holy grails. This unfortunately, was not one of them. It didn't do anything to remove stains, and while it didn't 'hurt' my teeth, it didn't exactly feel great. I'm sure it will work for other people, just not for me. I actually bought this a little while ago but just couldn't use it, so I'm passing it on to my dentist friend. Hopefully she'll like it and recommend it!

I use this product as a quick touch up to ensure that my teeth stay white. This is not a product that will whiten heavy stains. A more powerful treatment is need for that purpose. This is effective for basically maintaining white teeth or perhaps touching up very mild staining in a quick manner.

I have never used a whitener on my teeth as I didn't want the hassel of buying something and it not working. I was shopping on Paula's site and came across this and said sure why not! I don't have perfect teeth but was still able to angle the applicator to get into certain spots with no problem. It's quick, easy, and i saw results. I plan to get one for my husband who has tea stains, as other whiteners hurt his gums drastically! I would recommend this to anyone!!

This is didn't work for me at all. I was going to return it but realized that I bought it more then 2 months ago - shouldn't have waited that long to return; but I was hoping that I will find a way to use. NO ... it did ubsolutly nothing regardless of how i tried to use the product & it is very hard to apply ... very disappointing.

Was thrilled when I finally got the courage to purchase this product as I drink a fair amount of tea and soda drinks that I thought that this would brighten my smile and fill me with more confidence. However, I found that the times I have tried it I am there grinning so my teeth get the proper treatment and I feel like I'll get wrinkly just by waiting in that position - and then when it has been on the recommended amount of time there is no change what so ever. What a let down.

Long story short... This stuff is amAzing and extremly cheap.. Only thing is it doesn't last very long but WELL WORTH IT 100%

I use this touch up tool, not for long term whitening but for looking good for special occassions, or even daily for that white teeth look. And -- my teeth became whiter in general. While I was already using a toothpaste that whitens, this enhanced that whitening. In my 2X year visit, my son noticed my teeth were whiter. (He himself likes white teeth & goes to dentist for cleaning plus whitening.) I want more of this touch up tool so I always have it in my purse. Applicator could be better.

I do not see any difference though i have been using this for a month. Is it because I do not smoke and drink coffee? I regret buying this product and see why this is on 50% sale 24 7. I would recommend you avoid buying this product if you are don't drink coffee or smoke.

I think it works but the way it's dispensed leaves a lot to be desired and the instructions are vague at best. You look at the twist up tube and think really? I just put it right on my teeth? Doesn't get right in there. There's got to be a better way to put this on.

Just scraped the last of the product from within the tube: I liked the results although because my teeth aren't absolutely smoothly straight, I couldn't ever apply straight from the tube. I had to use my fingers to keep the product from gooping or getting stuck in corners. When the container is improved (and, I believe it will be) to be less wasteful, I'll order again.

I think this works pretty well for what its intended use. It's easy, does seem to lighten stains and doesn't cause sensitivity. My only concern is that the product becomes quite hard after it has been opened. I have to press/rub HARD to get the product onto my teeth, even if I first scrape off the tip. I ordered several of these (a couple for me, as well gifts for others), so hope the unused tubes don't have the same issue.

i have been using PC products for years but this one dissapointed. i used it as directed religiously but it did nothing for me. it does not apply well and the applicator is flimsy. i will not be getting this item again. 0 stars.

My teeth are naturally yellow and I'm a heavy coffee drinker. Using my Sonicare toothbrush and whitening toothpaste everyday has kept heavy stains away, yet I'm still left with yellowish cast and light stains on my teeth. I started using the Brighten Up product! I've never been able to tolerate other whitening products, and Paula's is so mild and fresh. First time I used it, I saw my teeth take on a less-yellow pearly gleam and mild stains disappeared. A handy, easy product that works.

I've been using this product because it's faster and less messy than what I was using previously. I go to the dentist twice a year for cleanings, and even the hygienist has noticed a difference in my teeth since I began using it a couple months ago. It is a pain to get the last remaining bit of stuff out of the twist-up tube, but the fact that it works so well without leaving my already sensitive teeth even moreso, I think it's well worth it.

This is a good product that does what it claims. My teeth are crooked, so using it from the tube doesn't reach everywhere. I solved this with a small, soft brush that brushes the product into all the crevices. For deep cleaning, repeated applications are needed. I tend to use it before parties or holidays, etc. Sadly, the last time I went to use it, it had turned to rock and no amount of effort helped.

When I purchased this I didn't expect it to work nearly as well as the whitening strips I've used in the past. However, within a few days, I saw comparable results without that terrible burning and sensitivity I have with the strips!

I wanted to love this. However, in practice it just doesn't work for me. It could be that it isn't strong enough. But that being said, the form of the product leaves much to be desired. I don't have very crooked teeth--had braces but teeth have shifted a tad--but the stick form just can't really get to some areas. The slight "foaming action" helps, but not enough. And because it's a twist-up tube, you can't use a large amount as you near the end, so it's wasted. Disappointed.

I like most of the Paula's Choice products I've purchased and decided to give this one a try. No bad taste or sensitivity but it was totally ineffective, a waste of time & money. My teeth are professionally cleaned 2 x a year, maybe this product works best on people who visit the dentist annually, and having surface tartar accumulation resulting from drinking black tea, colas and coffee throughout the day, smoking , or diet.

I've been using this for the past 2 weeks along with a drug store at home whitening system. The whitening system leaves my gums sensitive and I have to wait a few days between treatments. I use the Paula's choice whitener on the "off" days and it seems to help at least maintain the whiteness from the other stronger system. I'm not sure if it adding to the whiteness, but I'll keep using it for now. I don't know yet if I would repurchase.

I have been using this for more than two weeks but I do not see any difference. Is it because I am not a smoker? Anyways, this is the most disappointing product from PC. I guess there is a reason why this is on 50% sale for more than a month. I would never purchase this again.

I have used this product as needed for a few years now and at every visit with the dentist they always comment on how white my teeth are. As a 40 yr old coffee and tea drinker, I think that is a pretty good demonstration of the effectiveness of the product. I apply it when things start to look a little tan and use it once a day until they are pearly white again. I apply it as far back as my lips will allow and can definitely see a difference between the teeth applied and those that couldn't be reached. I have used the various tapes and trays, this is by far simpler to use and just as, if not more, effective for me. Sounds like it might not work for some other folks, that's really too bad. It's been a fantastic product for my coffeepot a day drinking husband also!

I have a real problem using teeth whiteners due to pain and nerve sensitivity. This one works really well, and is extremely gentle! It works quickly, doesn't travel all over my mouth and doesn't have a horrible taste or smell. On top of that it's extremely affordable compared to the ridiculous strip systems which left my gums in agony. It also gets in the space of my crowded teeth quite well. It's also ideal for using right before you hop in the shower, by the time my shower is done my teeth are significantly whiter! In addition, the added comfort means that I can use it more days in a row and get better results than I ever did with strips or other systems... which I tended to abandon quickly due to discomfort. Good job with this product PC, I hope you never stop making it -- or my teeth will suffer!!!

I am a 53 year old smoker and it works wonderfully for me. My teeth are very yellow, and I cannot use anyother whitening product at all. My teeth and gums became extremely sensitive after profesional whitenings ten years ago. I cannot even use minty tooth paste at all, it just burns. Any kind of Peroxide whiteners for my teeth burns greatly. So I am very satisfied with the ever so slight taste of this. Plus it really took off some of the yellowing from smoking. my teeth are getting better and better every day. I also noticed the diference the first use. Its a keeper for me. And it works for me. I love it. Please advise us if you ever discontinue this product, I will stock up.

I am surprised that people haven't loved this. I think it's amazing! I used it for several days in a row to deal with some yellowing I have on my front lower teeth. I'd also developed a couple of blue stains on my lower teeth (tops are veneers) from my toothpaste. Both were eliminated or significantly lightened. I have had my lowers professionally whitened, so this is more of a touch up than an overhaul. If you are looking for an overhaul, this is not the product for you. But, if you've had your teeth whitened and have minor discoloration from coffee, tea, etc, this is really great. Please keep making this product!
