Gingivitis?

In addition to daily good care ie brushing, flossing and of course a dental cleaning what rinses are good? Hydrogen peroxide, listerine, ???. ?
--------------------
My dentist recommends Plax for early stage gingivitis. Rinse thoroughly with it before brushing, soak your floss in the plax, floss your teeth, then brush your teeth and rinse with it again. The biggest favor you can do for yourself, if you smoke, STOP. Once I quit smoking, my gingivitis went away within a matter of a couple of weeks.
