Background: Green synthesized nanoparticles are perceived as an inexpensive, safe & ecologically beneficent approach to control pathogenic oral microbes compared to conventional methods. In the current study, silver nano particles (AgNPs) were effectively synthesised using clove and cardamom plant extracts. Methods: In the present study, aqueous silver nitrate was reacted with the clove, cardamom extracts and characterization was analyzed using UV-vis spectrophotometer and TEM analysis. Clove and cardamom reinforced silver nanoparticles were examined at 25 µL, 50 µL and 100 µL concentrations for their antibacterial activity against Staphylococcus aureus, Streptococcus mutans, Lactobacillus species and Candida albicans. Cytotoxicity was assessed using brine shrimp assays. Results: The formation of AgNPs was observed as shifting in color from orange-red color to dark brown at the end of the day three. Reducing silver ions to AgNPs, as shown by UV-vis spectroscopy, has produced an emission peak at 462 nm. TEM imaging showed that the particles were spherical and varied in size from 5-20 nm. Antimicrobial activity of the AgNPs at 100 µL was superior to that of antibiotics against Streptococcus mutans. Excellent antibacterial activity was shown by a zone of inhibition that was closer to that of antibiotics when examined against Lactobacillus. Staphylococcus aureus and Candida albicans were also moderately impacted. There was no evidence of cytotoxicity. Conclusion: Silver nanoparticles reinforced with clove and cardamom exhibited no cytotoxicity and showed promise as a potent antibacterial agent against oral pathogens
