Hydrogen Peroxide Halitosis 3% Hydrogen Peroxide And Water As Mouthwash?

3% Hydrogen Peroxide and Water as Mouthwash? - hydrogen peroxide halitosis

I have bad breath (the white sheet of bacteria on the tongue) and if the Swiss half water and half of the% hydrogen peroxide 3 was going on and I can my day without worrying about the breath away.

(I wash my tongue with Colgate at a time)

Is it harmful if I am going to use and before bed, as a mouthwash? What's the worst?

Thank you.
