This may be plaque induced gingivitis, so professional prophylaxis along with oral hygiene instructions should be sufficient to treat the disease.

This may be plaque induced gingivitis and patient needs comprehensive periodontal assessment as the next step to establish the diagnosis.

This may be periodontitis and subgingival debridement/instrumentation would be the next step in the treatment of the disease, followed by open flap debridement.

This may be periodontitis and the next step is comprehensive periodontal assessment which will enable establishment of an accurate diagnosis prior to proceeding with subgingival debridement.
