Question: how often should i gargle with hydrogen peroxide?
Answer: These active ingredients help to control or reduce gingivitis, plaque, halitosis, and tooth decay. Over-the-counter mouthwash products will contain 1.5%-3% hydrogen peroxide. The recommended at-home dilution for a hydrogen peroxide mouthwash is half water, half 3% H2O2 rinsing for one minute up to four times daily.
