This study aimed to investigate the effects of the ethanolic extracts of &lt;em&gt;Psidium guajava&lt;/em&gt;, &lt;em&gt;Glycyrrhiza glabra&lt;/em&gt; and &lt;em&gt;Syzygium aromaticum&lt;/em&gt; against cariogenic properties of &lt;em&gt;Streptococcus mutans&lt;/em&gt;. These medicinal plants have been used traditionally as the ingredients in the herbal mouthwash for the management of dental caries. &lt;strong&gt;Methods:&lt;/strong&gt; The 95% ethanolic extracts of these medicinal plants were prepared and their phytochemical contents were analyzed by using thin layer chromatography-densitometry. Antibacterial activities of the extracts against &lt;em&gt;S. mutans&lt;/em&gt; were evaluated according to broth dilution method. The effects of the extracts against cariogenic properties of &lt;em&gt;S. mutans&lt;/em&gt;, which are surface adherence, biofilm formation and acid production, were also investigated. &lt;strong&gt;Results: &lt;/strong&gt;The biological active constituents, quercetin, glycyrrhizic acid and eugenol, were found in &lt;em&gt;P. guajava, G. glabra and S. aromaticum&lt;/em&gt;, respectively. The three extracts possessed anti-bacterial activity against&lt;em&gt; S. mutans&lt;/em&gt; with the MICs of 1.562, 0.195 and 1.562 mg/mL, respectively. The extracts at every concentration tested (at lower than their MICs) significantly inhibited cariogenic properties of &lt;em&gt;S. mutans&lt;/em&gt;, which included inhibitions against surface adherence, biofilm formation and acid production. &lt;strong&gt;Conclusion:&lt;/strong&gt; The ethanolic extracts of guava leaves, licorice roots and cloves produced anti-bacterial and anti-cariogenic activities against &lt;em&gt;S. mutans&lt;/em&gt;. These plant extracts thus can potentially be developed as a product for the prevention of dental caries in the near future.&lt;/p&gt;
