Correct answer: A — Incision and drainage with dental source control

A localised dentoalveolar abscess in a healthy patient is treated with drainage and removal of the dental source through endodontic treatment or extraction. Antibiotics alone are not appropriate when drainage and source control are achievable and there are no systemic signs. The pearl is that drainage provides immediate decompression and reduces unnecessary antibiotic exposure.
