The presence of bleeding on probing indicates that there is some inflammation in the area, which may be due to the accumulation of subgingival plaque biofilm. Rescaling the area will remove any plaque biofilm that may be present and help to reduce the inflammation. The other options, such as subgingival irrigation, local or systemic antibiotic therapy, or antiseptic therapy, may be considered if the bleeding persists despite rescaling or if there are other signs of active periodontal disease, such as pockets or bone loss.
