Tooth decay, often known as dental caries, is one of the most common paediatric disorders globally. Despite significant breakthroughs in preventative and treatment strategies, it continues to harm the community. Silver Diamine Fluoride is an alkaline, colorless solution containing silver, fluoride, and ammonia. The use of silver diamine fluoride in the treatment and prevention of dental caries has been proven. Both children and adults have benefited from its use. Apart from these, the other features of SDF are being investigated and studies are being carried out. SDF is a non-invasive treatment that takes less time in the chair and is useful for individuals who are unwilling to cooperate. This treatment does not require the use of local anesthetic. When compared to other fluoride solutions, SDF penetrates deeper into the tooth. SDF contains fluoride, which induces remineralization and the development of fluorapatite crystals, making tooth structure more caries-resistant, silver which has antibacterial properties, fluoride, which has remineralization properties, and ammonia which acts as a stabilizer.
