EverSmile® PreOp™ is a 15-second pretreatment rinse designed for all dental patients. PreOp™ uses a 3.8% hydrogen peroxide, anionic surfactant formula to clean, disinfect, and debride the entire oral cavity before dental procedures begin. This exceeds the current American Dental Association recommendation of a 1.5% hydrogen peroxide pretreatment rinse. PreOp™ comes in mint.
