Low-Sensitivity Formula, Mint, Developed by Dentist. Made in USA by Ultradent. : Health & Household Review: Great product and it works! - Forgot all about this product until I ran across my trays. I ordered it immediately and started using it again. I can already notice a difference in color with just a few applications, and have no sensitivity to it at all. It’s the same product my dentist uses for a fraction of the cost. 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 Β£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 Β£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. ## Features - World's #1 Selling Professional Whitening Brand: Opalescence is trusted by more than 25,000 dentists, backed by 35 years of dental science and has helped brighten more than 150 million smiles worldwide. - UP TO 10 SHADES IN 7 DAYS: Professional 35% Carbamide Peroxide Formula: Dentist created whitening gel provides professional level whitening at home and can whiten teeth up to 5 shades.

Mike said he would not send my other 2 until I took down a negative review! Not fair!!!! **Q: whats the difference between 20% and 35 %?** A: I think the lower strength has to stay on for a longer period of time. When I first started wiih this I kept the trays on for hours and the 35% only stays on for 1/2 hour **Q: I have a diy mouthguard that i made from a mold. could i use that for the mouth trays or should i buy new trays?** A: You maybe able to use it as long as there is room for the gel in the tray. **Q: how long do you leave it on?** A: I been leave it over night, and according to my dentist that was the cause of my gum damages.35% it’s too much, I should not use more than 15% or even better to be 10% ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product and it works! *by M***E on August 14, 2026* Forgot all about this product until I ran across my trays.

This stuff makes your teeth noticeably whiter after the first use. There might be a little sensitivity, but nothing that has actually bothered me. It's cheaper for me to buy it here than from my dentist. I am not sure if he still sells it, but it was cheaper here. I wish I could find the melon flavored ones again, but that might have been a different potency. I love this product. It does what it says, I leave it on for 30 minutes, take a shower, get ready and then remove it and do a quick brush and notice my teeth look more white. Sometimes I clean house or play a game while it works and you don't need to use a lot so it lasts a while. ## Frequently Bought Together - Opalescence Mint 35% PF Refill Kit - Opalescence Whitening Toothpaste - Pack of 1 - Fluoride Oral Care - 4.7 Oz - Cool Mint - TP-5166-1 - Whiter Smile Labs Bump Pa BPA-free Teeth Whitening Tray (4 Pieces) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1813623-opalescence-35-carbamide-peroxide-teeth-whitening-gel-syringes-5197-2](https://www.desertcart.tn/products/1813623-opalescence-35-carbamide-peroxide-teeth-whitening-gel-syringes-5197-2) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-09*
