Abstract: Silver diamine fluoride (SDF) combines the antibacterial properties of silver and the remineralizing actions of fluoride in an alkaline solution that creates an unfavourable environment for collagen degradation. Clinical trials have proven the efficacy of SDF as a caries-arresting agent in primary teeth and root caries in the elderly. It is minimally invasive, inexpensive, safe and easy to apply, but a sign of arrest is the dark discoloration of the lesions where it is applied. SDF provides clinicians with a valuable additional tool in their armamentarium for caries management that aims to stop the disease process at the tooth surface, when traditional restorative therapy is not the best option, and when aesthetic results are not a concern.

Clinical relevance: Silver diamine fluoride (SDF) provides clinicians with an additional valuable option for arresting dental caries as part of a comprehensive caries management plan when traditional restorative therapy is not the best option.
