Chlorhexidine is a broad-spectrum antiseptic with lasting substantivity in the oral cavity, meaning it continues to exert antimicrobial effects after use. This makes it a reliable choice as a rinse to reduce dental plaque and the associated gingival inflammation, a well-established and widely studied application in everyday dental care.

In endodontics, chlorhexidine is valued as an irrigant because it provides persistent antimicrobial action within the root canal system and helps suppress residual microbes after mechanical cleaning. While it does not dissolve tissue like some other irrigants, its substantivity adds antimicrobial protection during and after canal preparation.

Subgingival delivery systems, such as gels or chips, have been explored, but the two most consistently supported and tested contexts in many resources are its use as a rinse and as an endodontic irrigant. Hence, combining these two uses reflects the main, well-established antimicrobial roles of chlorhexidine in dentistry.
