Opalescence PF 35% Teeth Whitening, Mint Flavor (2 Tubes with 4 Syringes)

The gel has gone off even if it was still in warranty. It is almost solid and cannot be spread well in the trays and it has a gone off smell. It also burnt my gums after a few minutes of using, probably because the texture is not good anymore and too much gel goes in the tray.

After 5mins my gums were burning and bleeding. I instantly washed the product off. The bleeding, swelling and burning lasted 3 days. Would not recommend.

This product truly does work and whitens your teeth very quickly! People are CONSTANTLY complimenting my smile and asking me how I keep my teeth so white. Mind you, I am a smoker and I drink coffee and tea all day long. I initially paid $400 at my dentist to get the professional trays that are a mold of my teeth and 8 syringes of this stuff. When used properly, it should last you a *minimum* of 2 months after DAILY use. It goes a long way, but I didn't realize how badly I was being ripped off! After finding it here on Amazon for this price, I was ecstatic! I immediately ordered it and have been using it since. There's absolutely no difference between this one and the one my dentist gave me, so I know it's the real deal. The only downside of this is that just like with most whitening solutions, your teeth do feel sensitive for a day or so after using. There were a couple of times I fell asleep with the mouth trays still on, and woke up in the morning to SEVERE sensitivity- but that was my fault since you're only supposed to leave it on for one hour. However, the super bad sensitivity only lasted one day. Also, don't use too much to where it's oozing out onto your gums because it burns like hell when it sits on your gums for a while! (Use only a tiny drop per tooth.) I got a remineralization gel here on Amazon, which is supposed to help with the sensitivity post-bleaching and it's made a world of a difference! As for the opalescence, I apply a small dot of the bleach closer to the bottom of each tooth on the tray that touches the front side of my teeth (so that it doesn't touch my gums when it spreads), and leave it on for about 1 hour before bedtime. I do it every night until I get the results I want, and then just maintain by using it for a 3-4 days in a row each month. (That's just my personal preference though, since like I mentioned, I smoke and drink tea and coffee every day so my teeth get stained rather quickly). Anyway, I can absolutely say that I truly do recommend opalescence to anyone who needs their teeth whitened. It WILL work, just remember that a little goes a long way!

I wasted a lot of money on a cheaper brand you can find on here (rhymes with MyShmile) for it to only whiten my teeth by a hair. This was even with their 35% gel and over week of treatments. It probably whitened by half a shade if at all. I should have just splurged on the Opalescent to begin with, because it would have saved me a lot of time and money. I'm an idiot for not taking a before, but it actually got my teeth noticeable whiter (beyond a doubt) on day 7. One thing I love is that if you have natural vampire fangs like me, whitening them makes them look a little more sharp and pointy. That was a pleasant surprise I wasn't expecting. I think it's because the white contrasts with your skin and the shadows in your mouth. Before you buy this, please be aware that you can severely burn your mouth and gums if you aren't careful with this stuff. Your enamel is strong enough to withstand it, but your flesh isn't. If you don't have the custom trays like me, I reccomend using a cheek retractor while painting each individual tooth with the syringe. This will also help to keep saliva away from the teeth/gel as it can deactivate the peroxide somewhat and won't be as effective. If the gel makes you drool like me and you want to further protect from saliva, tuck some cotton balls under your tongue and beside your back molars to absorb the moisture. Also tuck a towel under your chin like a bib. It's a learning curve to apply without the tray, but you get used to it.

I first got custom whitening trays about fourteen years ago - right after I had my braces removed. I have used just about every gel from several dentists. All of the gels have been far less than 35% and of course took a lot longer per treatment (usually overnight) and many more treatments than this product at 35%. And the gels cost SEVERAL times more from a dentist. One can achieve the same results as this 35% product, but it will take much longer, and will cost much more. There is a balance between the percentage of carbamide peroxide and gum irritation, however - and it varies from person to person (the irritation, that is). But here is what I have found. If I floss my teeth once a day and brush them two to three times a day and use a fluoride rinse "Act" at night, I can use the Opalescence 35% for one hour per treatment in custom trays. Even after one hour, I can see clear results. If my teeth are still too "dim" I can use it every day until I get the results I want. I know (sort of) if I have over done it because my dentist will tell me my teeth are "too" white and off his colour chart. I never tell him this, but I think his teeth are dim and stained. (Sorry if that is mean.) My tips: Brush your teeth at least twice a day with a fluoride toothpaste. Floss once a day and use Act fluoride rinse at night and use THIS gel. This gel is the best I have tried. It works quickly. Short treatment, few treatments. If you cannot tolerate an hour; use the recommended half hour. I don't have sensitivity, but if you do, switch to "Sensodine" sensitive teeth toothpaste and use the Opalescence less frequently, for a shorter time or both. Also, stop doing those shots of straight Bourbon, because that compounds the irritation to your gums. I vacillate about how often to touch up my teeth - so I asked another Amazon reviewer. Anyway, that is what works for me and I hope this helps you. A bright smile makes an awesome first impression. And second, third... Cheers, Dan

Wow, so I've been dabbling with 12% carbamide peroxide gel (aka hydrogen peroxide urea or CH6N2O3) for quite some time, purchased from a different company called SmileSciences. Their product worked ... albeit slowly, giving moderate results that were noticed over 2 to 3 weeks. Additionally the SmileSciences gel was used during the night (so, 6 - 7 hours) over that 2 to 3 week span. The Opalescence PF 35% Teeth Whitening carbamide peroxide solution, however, had noticeable effect on my teeth after a _single_ 30 minute treatment (using an AuraGlow 5x Blue LED Light Teeth Whitening Accelerator Light ). Everyone's biology is different, but the treatment left me with no teeth sensitivity aside from mild chemical burns on some of the gums that descend interdentally between my canine and pre-molars. The first time I used the solution, I was certainly liberal with the amount of gel applied within the retainers. The second time however, I used as little as possible to limit gel from escaping over the edges of the retainers, helping to prevent chemical burning of my gums. Another pro-tip is to not brush your gums as abrasively before applying the gel. I find that waiting 30 mins. to 1 hour after brushing helps limit chemical burns of the gums. HOW I TREATED THE TEETH: I use the Invisalign clear aligner system, and my dentist / orthodontist said the modern variants of the 3D-printed trays can double as whitening trays. That's what I use. From personal experience, using the store-bought, silicone ones that you bite into after submerging into boiling hot water, honestly, do not perform well at all. If you're seriously considering teeth whitening, you might want to consult your insurance for their orthodontia coverage and get a moulded tray. WARNING: DO NOT put too much Opalescence 35% gel in the aligners, because this particular gel with its high concentration of CH6N2O3 WILL almost certainly burn your gums. Vitamin E gel will almost immediately soothe the pain and also immediately promote healing. Get it at Trader Joe's or online: you'll thank me.
