What Is Silver Subfluoride Used For?

Silver subfluoride (Ag₂F) is a chemical compound that is used mainly in dentistry for the treatment of tooth decay. It has antibacterial properties and can be used as a cavity liner, which helps to protect the tooth pulp from further decay and infection.

When a tooth is prepared for a filling, some of the infected or decayed tissue must be removed. Once the decayed tissue is removed, the dentist will typically place a dental liner onto the remaining tooth structure before placing the filling material. This liner serves as a protective barrier between the filling material and the tooth pulp, reducing the risk of sensitivity and further decay.

Silver subfluoride has been shown to have a number of advantages over other cavity liners. It forms a strong bond with the tooth structure, is highly resistant to bacterial growth, and has a long-lasting effect. In addition, it does not break down over time, making it an ideal choice for patients who require long-term protection against tooth decay.

However, it should be noted that the use of silver subfluoride is controversial due to its potential toxicity. Some studies have suggested that it may cause harm to the surrounding tissues and organs, particularly if ingested or absorbed into the bloodstream. As such, it is important for dentists to exercise caution when using this material and to carefully monitor their patients for any signs of adverse reactions.
