When using any mouthwash, it is vital to swish it around your mouth for at least 30 seconds before spitting it out. This will give the mouthwash enough time to kill the bacteria in your mouth. If you have any cuts or scrapes in your mouth, it is essential to avoid using hydrogen peroxide. The chemical can irritate and delay healing. If you have open wounds in your mouth, consult your doctor or dentist before using hydrogen peroxide.
