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% ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1813623-35-carbamide-peroxide-teeth-whitening-gel-syringes-5197-2-4](https://www.desertcart.us/products/1813623-35-carbamide-peroxide-teeth-whitening-gel-syringes-5197-2-4) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-09*
