In brief: Daily - if diluted

One cup of water mixed with 1 tbsp.
Of 3 percent hydrogen peroxide is an easy and antiseptic home remedy mouthwash that can be used daily. You can mix equal parts hydrogen peroxide and water if you have canker sores. Don't worry if the mixture foams a bit when you're rinsing. Make sure to spit and rinse afterwards. Do not swallow.

In brief: Don't

Peroxide is a great antiseptic wound cleanser. There is no real benefit of rinsing your mouth with peroxide than something like listerine won't do as well or better.
