## Description

Opalescenece teeth whitening gel syringes.

Review: 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.
Review: I love Opalescence. It works so well. I wish I would have taken before and after pictures. I'm stingy with 5 stars, but they deserve it.

*by T***R on 16 March 2015*

These are definitely 35% and they are definitely STRONG. I cannot reiterate that enough. I used to use NiteWhite, but I switched to Opalescence after my dentist gave me a couple with my new whitening trays (my teeth have moved from my TMJ). He actually gave me 20%. I didn't like them at first because they are like a sticky gel, whereas the NiteWhite, which I was used to, was more like a toothpaste consistency. I ended up really liking the fact that the opalescence is a sticky gel, because it doesn't move around in the tray and sticks my trays to my teeth. Because of this, I also don't have to spit out the extra whitening stuff that seeps out from the trays like my last brand. Anyway, I go all out when I do things, so I decided on the 35% like I used to have in the NiteWhite, but these are SO much stronger. You should only leave them in 20 minutes to 35 minutes MAX! Otherwise you will have some serious sensitivity pain. I left them in for an hour once and I will never do that again. I also have to note that if you get this gel on your gums it will BURN really badly. To the point where you think it might actually burn a hole in your gums. Yikes. I've had to take them out and try again later because of this. That's why I'm giving it 4 stars. I feel like I can't get the gel as close to my gums as I would like to for fear of it burning the crap out of them. I'm going to give some of them to my siblings and I'll go for the 20% next time I order! Overall, this stuff is bomb. My teeth are noticeably whiter after even just one application. :)
