Opalescence35% CP Mint - Gel Syringes Teeth Whitening - Refill Kit (2 Packs / 4 Syringes Total) Carbamide Peroxide Gel. Made by Ultradent. Tooth Whitening Refill Syringes 5197-2

These 35% teeth gel whiteners are the same brand and percentage that was supplied to me by my dentist. These work really well. I find the application makes it very easy to drop just the right amount into my retainer. You can also just put the whitener on specific locations within your retainer. These cost much less than my dentist charges and they do the exact same job.

I recently purchased the Opalescence Teeth Whitening Gel, and I must say, it has exceeded all my expectations. This product is nothing short of wonderful!Effective Whitening: The gel delivers noticeable results in a short amount of time. After just a few applications, I could see a significant improvement in the whiteness of my teeth. The difference is remarkable, and I feel much more confident with my smile now.Easy to Use: The application process is straightforward and user-friendly. The gel comes with clear instructions, making it easy for anyone to use at home. The syringe-style applicator ensures precise application, reducing wastage and ensuring even coverage.Comfortable Experience: Unlike some other whitening products I've tried in the past, Opalescence Teeth Whitening Gel is gentle on the teeth and gums. I experienced no sensitivity or discomfort during the whitening process, which is a huge plus.Professional Quality: This product feels like it provides professional-level results from the comfort of my own home. It's evident that a lot of research and quality control has gone into making this gel effective and safe for everyday use.Great Value: Given the impressive results, I find the Opalescence Teeth Whitening Gel to be excellent value for money. The pack contains enough gel for multiple treatments, making it a cost-effective solution for maintaining a bright, white smile.

I used Opalescence years ago as a Dental Assistant before we could buy online and it was my favorite. I tried this for only 15 minutes to check sensitivity and it honestly whitened at least one shade with no sensitivity. Oh the glory of carbamide peroxide!*Please note*You only need one tiny drop in each facial side of your trays in the tooth-groove. It will liquify and surround the surface of teeth. If you use too much, you run the risk of getting on the gum surface and it will cause irritation. Start slowly if you have sensitivity. This stuff is awesome

Excellent productLove itWhitening your teeth is so easy

Works well! It’s super strong and burnt my gums, it hurt and turned them white which was scary! I came up with the idea to put the gel on a q-tip, put it on my teeth and then I insert the retainer that way it never touches my gums, works perfectly!

oh my god this stuff works miracles! i am a vape user as well as a coffee drinker and after three 30min sessions (once a day for 3 days) i have pearly whites again! the results were visible after just the 1st sessionit is very strong and the reviews about it burning your gums are very true, i read someone say they applied it with a q-tip avoiding the gums and it works great :)

I notice a big difference with this gel in comparison to competitors like Crest. Using these in a molded teeth tray are less messy than the disposable crest strips

With products as this, it is best to precursor the review with some instruction and expectation setting:Instructions:--This product is meant to be used as a refill to custom trays fitted by your dentist. Otherwise, you will have issues with uneven application and gum burning.--Application muust follow instructions that are provided. Do not overapply or the gel will burn your gums and turn them white for a little while.Expectations:--At the end of the day, research suggests that the 35% whitens as much as the 15%. The difference is twofold: The 35% needs to onlt stay on for 30 minutes, but the 15% needs to stay on an hour. Second, the 35% will get your teeth whiter faster. E.g., if it takes 12 weeks for the 15% to get to the desired whitening, it may take 8 weeks for the 35%.--The 35% will make your teeth more sensitive than 15%. For me, it was worth the extra sensitivity to get faster results.--It takes time! Results do not occur overnight for most people. Expect 12-16 weeks, applying once a day at night for 30 minutes. If it occurs faster, use the remaining gel to periodically keep them white.--The gum line part of the tooth may still be yellowish. My guess is it is hard to get right to the gum line without burning. So the application will still be a little uneven.My review:I had noticable results after 4 weeks, from 2-4 shades. One tooth was 4 shades, most were 3, and the rest were 1 to 2. I am under Dentist care for the entire process.For the 4 week period, the Dentist was highly pleased with the progress. I was pleased as well. After 6 weeks, though, the progress seemed slower, and the lower teeth are still too yellow.As well, one issue remains: one upper front tooth would not whiten well. It had undergone tramua when I was young. So, the 2 upper front teeth will need veneers. Right now it is a race to whiten as much as possible to get the whitest shade of veneers possible.My method:-- I used 12) 15% gel for 6 weeks that the denstist provided-- I used (8)35% gel for 4 weeks that I bought from Amazon-- I applied twice a day for at least half the time-- I used between 1/3 to 1/2 of the syringe per applicationIn all, you have to be patient and not expect quick results. Some teeth will whiten faster and others may not whiten much at all. From what I researched and the Denist's input, results widely vary. However, you should certainly see viable results and the effort is not hard. 30 minutes after bushing and flossing is pretty easy.I disagree with the low ratings for this product. Just because someone does not use the product properly, does not reflect on the product quality. Results based on non-custom trays are invalid in my opinion and should not reflect on the rating.I would have given a 5 star, but I felt somehow they need to get the gel to the gumline without burning, providing full tooth coverage.
