I bought this at Shoppers Drug Mart the other day when I went out to buy some type of whitening product to use with my whitening toothpaste to hopefully boost the minimal results. This was the only non-strip type product available and much cheaper than any of the other products. I was sure it was probably garbage considering the major price difference from the other products (about $6.50 CAD compared to $30-$70 CAD) and that the box resembled the cheap-looking "As Seen On TV" style of packaging. I decided to try it anyways since the strips are all fairly expensive and I don't know whether they'll work either. From what I understand, this product used to come with a whitening tray. Now they just expect you to apply it to bare teeth with a cotton swap and try to leave it on for 5 minutes, which has proven to be very difficult for me. The gel doesn't want to stay in place, especially on my lower teeth where the saliva gathers, and it makes the insides of my lips feel weird. With a tray, I imagine this would sooo much easier! However, I've used it 4 times now (2 days of treatments) and I am seeing a small improvement already, so I guess it still manages to work in these less-than-ideal conditions! I guess I should add that I'm also a non-smoker and I don't drink coffee, tea or wine, so my teeth aren't that far from white to begin with, not to mention that I'm also using a peroxide toothpaste (Colgate Visible White) 2-3 times daily. I have yet to experience any sensitivity, even with using two whitening products together, but my teeth have never been sensitive. I guess only time will tell how well this stuff really works. It's only been 2 days so I've still got a long ways to go. I'll update my review if/as needed.
Update 08/30/2008: I've been getting really frustrated trying to get this gel to stay on my teeth (and off my lips) for any amount of time, so I had an idea today. I cut up some old costume vampire fangs to use as whitening trays. I'll see how that goes.
Update 08/31/2008: So, the vampire fangs makeshift whitening trays do help. I need to find some cheap ones that fit better though because the only ones I had (just really cheap ones that came with some fake blood from a past halloween costume) are way too big and square for my jaw and are painful to wear. Should be easy enough to find different ones right now considering that most of the stores have their halloween stuff out already. They just have to fit around my teeth half decently. I feel pretty goofy wearing them twice a day but they're a lot cheaper than buying whitening trays and they keep the peroxide on my teeth and off my lips! Sometimes you just have to be creative!
Update 09/09/08: I stopped using this for a bit as I was frustrated with the application, but then I started again, trying different ways... and my teeth are definitely looking whiter! They're not quite paper white but definitely noticeably whiter. I'd highly recommend this product. You just need to have patience. I've never tried Crest Whitestripes but from what I've read and understand, this is probably more effective... and so much cheaper! And probably a lot less sensitizing compared to a lot of the whitening products. I still haven't experienced any sensitivity while using this product. The worst it'll do is make the insides of my lips feel weird if I don't protect them.
Update 10/29/2008: I'm still using this on and off as needed and will be starting my second tube soon. It really does make a difference. I can get my teeth looking almost paper white with just this product and an Arm & Hammer toothpaste. I noticed the bottoms of my lower front teeth (where I was a bit lazy with application before) were looking stained in contrast to my now-whiter upper teeth, so I started focusing the gel application more in those areas and the difference in colour is now becoming less obvious as those areas are becoming whiter as well. I would recommend giving this stuff a try. It's cheap enough to take a gamble on anyways.
