A is correct. A cracked but intact acrylic denture should be professionally assessed and repaired; self-cured acrylic resin is an established denture repair material. The clinician should also identify predisposing factors, such as poor fit, occlusal imbalance or an inadequate base, because repair without correcting the cause risks recurrence. NHS advice is to bring damaged or broken dentures to a dentist to determine whether repair is possible. Household adhesive is unsuitable and may compromise accurate repair. Waiting for complete separation permits further damage and leaves the patient without a usable appliance. Immediate replacement is unnecessary when a repair is feasible. Composite applied only to the polished surface does not provide a proper structural acrylic repair. Reinforcement may be considered for repeated fractures, but it is not required routinely for this initial crack.
