Minimally Invasive Dentistry Practice Test

Silver diamine fluoride is used in minimally invasive dentistry to stop active caries without drilling. It’s especially helpful for young children, uncooperative patients, or lesions that are hard to access where conventional restorations are challenging. The silver and fluoride components help kill caries bacteria and harden the softened dentin, effectively arresting decay and preserving tooth structure.

The main drawback is that the treated carious area darkens permanently, typically becoming a black or dark brown stain. This esthetic change is a significant consideration for anterior teeth and for patients who value appearance. SDF does not remove the decay by itself, and a definitive restoration may still be needed later for function or esthetics.
