Question: can you rinse your mouth with hydrogen peroxide to whiten teeth?
Answer: Using hydrogen peroxide as a rinse: Mix equal amounts hydrogen peroxide with water, such as 1/2 cup to 1/2 cup. Swish this mixture around your mouth for about 30 seconds to 1 minute. Stop and spit out the solution if it's hurting your mouth and try not to swallow any of the mixture.
