Methods of using oxidative reduction potential (ORP) water solution that is stable for at least twenty-four hours in dental applications are provided. The ORP water solution can be administered to patients for the routine disinfection of the oral cavity as part of an on-going program of oral hygiene. The ORP water solution can further be used to irrigate and/or disinfect oral tissues and surfaces during dental procedures, oral surgery, or maxillo-facial surgery. Also, the ORP water solution can be administered to treat patients with damage to the oral tissues caused by disease or surgery.
