Hydrogen : Hydrogen peroxide helps in reducing bacterial levels around the gumline. By releasing oxygen, it kills anerobic bacteria and also helps flush out debris. I would not mix it with listerine. Use the listerine separately, on a different day. Hope this info helps.

The : The standard answer applies here: do not reinvent the wheel. Dental companies spend an enormous amount of resources researching which mouthwash works. Listerine and other ada accepted mouth rinses work. Generally peroxide is not considered a mouth rinse. What keeps your mouth cleaner is the actual action of brushing and flossing your teeth. The effects of oral rinse are minor. Concentrate on brushing and flossing. It is start more important than the marginal effects of rinsing.

Do not use: Hydrogen peroxide is very toxic and not meant to be used in this way. Brushing and flossing is main defense against gum disease. Using an antiseptic mouthwash may add a small benefit but doesn't take place of brushing and flossing.

Not recommended: Hydrogen peroxide is safe to use topically for your teeth. However, do not use hydrogen peroxide as a regular part of an oral care routine.
