Opalescence 35% Teeth Whitening Gel Refill Syringes (4ct) - 5197-2 | 35% Carbamide Peroxide Whitening Gel for Custom Trays. Low-Sensitivity Formula, Mint, Dentist Developed Made in USA.

So I’ve used different whitenings products in the past but this one is the most effective one! Iam super happy with the results I have stains on my teeth of years smocking and drinking coffee, after 4 days started to whitening my teeth and they get whiter I will keep going with the treatment 4 more days, the only issue that I got is that burn my gums a little, after the 3rd use but the product should not touch the gums I will try to be more careful next time how about iam applying it, but iam supper happy. Usually I don’t have sensitive teeth or gums, I have the 35% and I keep it one hour every night before I go to bed. So I got trays that I mold, I apply half tube on each tray I place them the product is thick and helps the trays to stick in my mouth without moving and that’s very helpful and I keep them on for one hours as the box saying, and after I brush my teeth to take the excess product out and clean my trays very well with toothbrush and water. Be careful to do not touch the gums it’s very strong whitening gel.

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 !!!

I am not so consistent with it just because of how sensitive your teeth are after you use. But combine it with the toothpaste and you will use it al the time.

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.

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.

This really works.

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 custom made dental trays and started bleaching in the 1990's, using Philips Nite White Zoom. The results were amazing, but my dentist office switched to using Opalesence, so I ordered due to wearing it just a short while an hour or so, instead of overnight. So far I've used 2 syringes, this stuff is way more sticky gooey, perhaps it's old product, or stored in wrong temperature? Zoom was never thick like this, it went into the trays much easier. This is the first time I've used 35%, I use to use16 or 22% but so far I don't have sensitivity. I saw my dentist yesterday and he could see the difference in 2 weeks since I was last there. I like the mint flavor Opalescence offers. I have 2 more syringes to use and get about 2 applications out of each syringe. I'm only doing upper teeth so I can detect changes easily by comparing to bottom teeth. I wear it for about 1 hour of just over. I will update my review if there are more noticeable changes. Price for product was reasonable, and shipping was very fast.

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
