Silver Diamine Fluoride....

Silver diamine fluoride (SDF) is a liquid Used on cavities to help stop tooth decay

and prevent the damaging progression of the disease. It can be used in conjunction with other therapies and also can help relieve sensitivity. Treatment with SDF does not eliminate the need for dental fillings or crowns to Repair function or Aesthetics

Upon application to the decayed surface, a layer of silver protein conjugates forms, increasing resistance to acid dissolution and enzymatic digestion. Hydroxyapatite and fluorapatite form. The treated lesion increases in mineral density and hardness while the lesion depth decreases. The silver acts as an antimicrobial, the fluoride acts to remineralize, and the proteins that break down the dentin are inhibited. The ammonia acts as a stabilizer. SDF will always color anything with collagen. It will stain decayed or demineralized sites and soft tissues, but not healthy areas.
