You may not qualify if…

• Subjects are excluded from participation if any of the following apply:
• Advanced periodontal disease
• Active caries lesion(s) within 30 days prior to study drug administration (confirmed by dental examination and standard radiographs).
• Medical condition (e.g., artificial heart valve, history of infective endocarditis, cardiac transplant with valvular dysfunction, congenital heart disease or total joint replacement) for which antibiotics are recommended prior to dental visits and/or procedures
• Pathologic lesions of the oral cavity (suspicious or confirmed)
• Full or partial dentures, or orthodontic appliances, e.g. night guards, permanent retainers
• Impaired salivary function (unable to provide 2 mL of stimulated saliva within 5 minutes)
• Use of systemic antibiotics, topical oral antibiotics, or use of other drugs, which in the opinion of the Investigator could influence the study outcome, within 30 days prior to Screening
• Medical history indicating the woman is pregnant, breastfeeding/lactating or she has a positive urine pregnancy test
• Participation in a clinical trial or receipt of a non-FDA approved therapy within 30 days prior to study drug administration (depending on the specifics, participation in an observational study is not necessarily excluded)
• Presence of any condition or concurrent illness, which in the opinion of the Investigator, would compromise normal immune function (e.g., diabetes, rheumatoid arthritis, lupus, liver disease, organ transplant, etc.), interfere with the use of study dentifrice and oral care products, or interfere with the ability to comply with study requirements
