## Description

desertcart.com: Opalescence 35% Gel Syringes Teeth Whitening - Refill Kit (12 Syringes), Made by Ultradent, Carbamide Peroxide in Mint Flavor. Tooth Whitening 5197-12 : Health & Household

Review: Love my pearly whites! 😁 - 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 desertcart 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 desertcart, 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!
Review: Excellent but take caution as it can cause chemical burn on gums - Recently I decided to take care of my oral and dental hygiene. After visiting the dentist and having some fillings carried out I asked him whether my teeth could be whitened and how much the cost was. He replied yes and the bill was around £300! Not exactly small potatoes. Whilst I had no inclination whether the price was reasonable at the time I decided to do some research and try out certain products. I have tried the Crest strips a year or so ago and unfortunately they did very little after buying 2 weeks worth supplies and whitening every day. Upon further research it was mentioned that the active agent would be neutralized with saliva so the whitening effect wouldn't be as effective as a professional job. All it would do is froth up in your mouth and not produce noticeable results. This led me to having custom dental trays made from Ebay where they send you some putty for you to make a mould of your teeth and you send it back for them to make custom dental trays. I then ordered some Opalescence 35% from desertcart USA. EU laws unfortunately require anything over 0.1% Hydrogen Peroxide can only be carried out by dentists so I was forced to take that route. Not knowing how much I would need I just bought a 3 pack. Each pack contains 4 syringes. Also since I was going to get stung by customs which I paid for in advance during checkout I took the gamble and bought extra just in case they gave good results. In order to quantify any difference I bought a basic tooth shade guide of Ebay. I started of at a shade 9-10 (My teeth still had intrinsic tar stains from my smoking days and heavy tea stains. We Brits love tea) I finished at a shade of 2 (I only used 5 syringes to get this result. Amazing! Dazzling! Very Joey Essex lol). I decided that this was bright/white enough. Anymore then I would look like Ross from Friends. Please bear in mind monitors and taking camera pictures may distort the colours. I did not add any extra artificial effects, ISO were the same, no exposure was added but due to the difference in lighting the F stops may have been different. Pictures were taken 5 days after whitening treatment so there is no dehydration on the teeth which produce fake whiter results. I was able to use one syringe to do two treatments which I did every second day if my gums needed time to heal or my teeth were too sensitive. Prior to receiving the Opalescence I rubbed vitamin E oil onto my gums, twice a day. As long as you don't overfill the dental trays there should be minimal "spillage" onto the gums that cause chemical burn. I did find that my gums went white when spillage happened and it did cause chemical burn but it healed after a day. My pain threshold is quite high so I was able to bear it but I did give time to heal until I started treatment again. The whitening agent I could hear gently fizzing away slightly during treatment so I knew that it was doing it's magic. Common sense is just involved, if gums hurt then give it time to heal and using vitamin E which is an anti inflammatory does wonders. My whitening treatment contained 35% carbamide peroxide which is around 14% hydrogen peroxide so if it causes excessive pain then reduce the treatment time. I could only bear 30 mins at the beginning but after the second syringe I was able to withstand an hour session. The longer the whitening agent stays on your teeth the more it will be able to break down the bonds of molecules that cause stain. To combat the inevitable tooth sensitivity I used GC tooth moose which also remineralizes teeth and brushed my teeth with Biorepair plus toothpaste. Sensodyne Pronamel works equally well in repairing enamel. Things like Blue plasma lights are a placebo. They do nothing and research has proved it. You can buy a cheap one from Ebay for £3 for psychological assurance but trust me not worth wasting money on (I bought one and it did nothing). I have 6 syringes left and plenty to retouch my teeth over the year or longer to maintain brightness/whiteness. Overall I am very pleased with the outcome but would advise that anyone who wants to go down the DIY route sees a Dental professional first during their checkup and ask whether their teeth is in good condition for whitening treatment. Edit on Novermber 12th 2016. This product has a shelf life of 2 years if refrigerated. I came back to re-do my whitening after 11 months and the potency of the product has reduced greatly from when I first bought it. They were kept refrigerated as specified but don't seem to work as well as when I first received them. So buyer beware if you intend to buy in bulk and store them.
