AT BASELINE (Visit 2; Prior to Dental Prophylaxis):
1. A participant with 10% - 30% bleeding sites.
2. A participant with mean interproximal whole mouth TPI score \>=1.5.
Exclusion Criteria:

* A participant with, in the opinion of the investigator or medically qualified designee, an acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator or medically qualified designee, would make the participant inappropriate for entry into this study.
* A participant who has any other clinical serious or unstable conditions (example, cardiovascular diseases, diabetes, liver disorders, and kidney disorders) which could have affected study outcomes and/or participant safety.
