After placing a crown on a primary molar, the key issue during follow-up is detecting problems that threaten the crown seal and the tooth beneath. If radiographs show recurrent caries at the crown margins or the crown is dislodged, it indicates a breakdown in the fit or cementation and a pathway for decay or bacterial invasion under or around the crown. This situation can allow quick progression of caries toward the pulp in a primary tooth or lead to infection of surrounding tissues, so it demands urgent reassessment to decide whether the crown needs to be re-cemented, repaired, replaced, or the tooth extracted if saving it is not feasible. In contrast, normal gingival health, only a change in crown shade, or minor occlusal wear without symptoms suggests stability and does not require immediate action, though continued monitoring is still appropriate.
