## Description

desertcart.com: Opalescence 35% Carbamide Peroxide Teeth Whitening Gel Syringes - 5197-2 | (4 Units) Refills for Trays. Low-Sensitivity Formula, Mint, Developed by Dentist. Made in USA by Ultradent. : Health & Household

Review: A favorite of mine. - This stuff is the bomb. I have a retainer as I had braces (as an adult). 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.
Review: Amazing product, be careful about the gums shouldn’t touch them! - 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.

## Questions & Answers

**Q: How often can you use it?**
A: DFW Dental Supplies only sent me 2 syringes. 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%

### ⭐⭐⭐⭐⭐ Great product and it works!
*by M***E on August 14, 2026*

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.
