Objective: The objective is to remove the local etiological factors responsible for inflammatory gingival enlargement and restore the physiological form of the gingiva. Methodology: A 31-year-old female patient presented with soft, discoloured, tender gingiva with ballooning of the papilla and margins along with generalised plaque and calculus suggestive of generalised chronic inflammatory gingival enlargement on the basis of exclusion of other causes. Meticulous scaling and root planing were performed quadrant-wise weekly. Results: Within a month of non-surgical periodontal therapy, gingival enlargement had reduced markedly, and the patient was put on an oral hygiene maintenance programme. No remission of enlargement was observed after 6 months of follow up. Conclusion: For plaque-induced periodontal disease, non-surgical therapy is still a gold standard among all the therapies available.
