What is the purpose of a periodontal dressing?

The primary purpose of a periodontal dressing is to be placed over a surgical site following periodontal surgery. This dressing aids in protecting the surgical area, helps control bleeding, and assists in the healing process by keeping the tissues in position. It acts as a barrier against physical irritants and contaminants that could affect healing, providing a protective coating that helps maintain stability in the area where periodontal tissue has been manipulated.

Other options do not fully capture the specific role that a periodontal dressing plays. While temporary restorations and filling materials serve distinct functions in dental procedures, and aesthetic purposes can be relevant in some contexts, the defining characteristic of a periodontal dressing is its protective and supportive role following surgical interventions.
