This is necrotising gingivitis: pain, halitosis and punched-out interdental papillae in a smoker with a relevant stress-related risk factor. In a patient without fever, facial swelling or lymphadenopathy, SDCEP recommends local plaque/calculus removal as tolerated, oral-hygiene instruction and short-term chemical plaque control, such as 0.2% chlorhexidine. Therefore D is the best initial management. A inappropriately delays treatment of an acute destructive condition. B is unjustified before conservative management and assessment of prognosis. C is incorrect because antibiotics do not replace local measures and are reserved for spreading/systemic infection or inability to complete local treatment. E is not initial management; acute tissue excision would be unnecessarily destructive.
