Over time, there has been a lot of interest in the synthesis of green AgNPs utilising plant extracts due to the remarkable antibacterial capabilities of these nanoparticles. These particles' nanosized makes it easier for them to pass through cell membranes, interacts with internal organelles, and eventually damages cells when they proliferate. With the exceptional benefits, including practicality, simplicity of usage, and the utilisation of specialised processes like bacteria, plants are currently the preferred method for synthesising metal nanoparticles. Based on the idea of converting silver ions (Ag+) to silver nanoparticles (Ag0), green synthesis techniques for the synthesis of silver nanoparticles are provided. The literature reveals that the modified metal nano particles modifying with green methods are already practicing by dental clinicians, whereas still less percentage of practitioners are using this green nano technology. Hence this narrative review includes different metal nano particles using in dentistry and different green methods using to modify the environmentally friendly dental practices.
