Opalescence 35% - Teeth Whitening Kit Refill Gel Syringes (4 Units) - Carbamide Peroxide Gel. CP Mint - Made by Ultradent. 5197-2

First session teeth noticeably whiter this product is insanely good, I wouldn’t think twice about getting it. Only wish I would’ve went for the 45% instead of 35%. I don’t believe I’ll need another batch but if I do will go for the 45%.

Great whitening gel, great for sensitive teeth. My Dentist recommeded this to me. I'm a heavy coffee drinker and this product gave me back my pearly whites. Highly recommend

Bought these initially from my dentist, then realized I could buy them on Amazon at less of a markup. I load them into my retainer trays that I got after finishing Invisalign which gives me a great fit, but I imagine you could put them into any tray and get the same results. They last a while and are very very effective. I haven’t experienced any major sensitivity with responsible use and proper breaks between treatments.

I have sensitive teeth and gums, and I followed the included instructions and stepped up the time I had it on from 20 minutes, then 40, then 1 hour. After just 3 uses my teeth are noticeably whiter. Doesn't have any weird taste, is easy to use. Overall definitely would recommend.

Used before wedding for the first time - thought i was whitening the front of my teeth, but it even removed molar stains that have been around for years. Downside is it burns if it touches your gums and can cause discoloration, but it does the job effectively.

I was purchasing the identical product from my dentist for years. I was paying $50.00 for 2 tubes. I paid $35.00 for 4 tubes on Amazon. A wonderful whitening gel. I have no sensitivity at all using this as others have mentioned Highly recommend !!!

Product works, juts don’t leave for tos long. 10 minutes max. Will burn gums if you leave for more than 10 minutes. Also be ready to use sensitive tooth pastes the next week after use.

I couldn't be more pleased! My teeth look great and I'll buy another package to keep on hand for a monthly "refresh" I think. This 4 pack was half the price of the exact same product sold in my dentist's office. I already had custom molds but I'm pretty sure you could use them with the sport molds that you heat and put in your mouth to shape.

Best whitening gel on the market- sold at most dental offices. Be careful as it can easily bleach the gums if you do not have properly fitted trays! Only wear them for about 25 mins max. Bleaching goes away in about 2 hours (swish w warm salt water until gums heal).

Excellent products and excellent customer service as well
