History and Usage:

Very powerful, 22 percent carbamide peroxide refill gel is a high-viscosity gel that is great for those seeking extra-whitening power for tougher stains and faster whitening. This is the strongest, nonglycerin-based gel made, so you get the highest power with the lowest sensitivity. This is the gel of choice for overnight bleaching with our custom lab-created mouthpieces. Our oversized, prefilled syringes (5 ml each) contain more whitening gel than most others and provide ten (10) whitening applications each, offering a total of 30 whitening applications. This gel is the exact formula professional dental offices use. 

Label Information and Ingredients: Each package contains:

• 3 Syringes (5ml each) of Professional Whitening Gel (22% Carbamide Peroxide)
• Detailed Usage Instructions
