 1. Silver has been used in medicine for centuries due to its antimicrobial properties. 2. Silver nanoparticles have been synthesized and incorporated into biomaterials, providing great antimicrobial effect at low filler levels. 3. This review discusses the current progress in using silver nanoparticles in dentistry to prevent or reduce biofilm formation on dental material surfaces, highlighting aspects such as antimicrobial potential, mechanical properties, cytotoxicity, and long-term effectiveness. Further studies are needed to determine optimal concentration and release of silver nanoparticles over time.
