An uncooperative patient with a cavity traveled a long distance to see you. What is the most appropriate non-invasive management?

Silver diamine fluoride (SDF) is an ideal choice for uncooperative patients because it is a non-invasive caries-arresting agent. It requires no drilling or anesthesia, making it suitable when patient cooperation is limited. SDF kills cariogenic bacteria, remineralizes dentin, and arrests active caries. The primary limitation is that it stains the carious dentin black. Composite and amalgam require proper isolation and cooperation. Interim therapeutic restorations are another option but still require some preparation.
