Just use your own trays with our bleach to keep your teeth as white as possible.
The delicious melon or mint flavored Opalescence gel is worn overnight, while you sleep for ultimate performance and maximum convenience. The patented formula bleaches in as little as 30 minutes in 1-3 daily treatments or for 1-6 hours daytime (if worn overnight, gel will stay active for 8-10 hours).
The active ingredient in Opalescence, carbamide peroxide, has been recognized by the FDA for many years as an oral antiseptic and is now used for its superior tooth whitening properties. Fluoride and potassium nitrate are added to reduce the amount of tooth sensitivity.
