Our main objective for this study was to investigate the presence and prevalence of these oral bacteria in wastewater to determine the feasibility of using WBE for oral pathogens. We measured\n                    <jats:italic>S. mutans<\/jats:italic>\n                    and\n                    <jats:italic>P. gingivalis<\/jats:italic>\n                    nucleic acids in weekly samples for 24 months at a local wastewater treatment plant. Between June 2023 and May 2025, a weekly sample of untreated wastewater was collected, resulting in a total of 100 samples collected over the timespan. Samples were concentrated, extracted for DNA, and then tested for each bacterium. Our results showed that 89% and 58% were positive for\n                    <jats:italic>S. mutans<\/jats:italic>\n                    and\n                    <jats:italic>P. gingivalis<\/jats:italic>\n                    , respectively, which shows that wastewater surveillance is appropriate for oral bacteria. Average concentrations were 4.57 log\n                    <jats:sub>10<\/jats:sub>\n                    genome copies\/L and 3.03 log\n                    <jats:sub>10<\/jats:sub>\n                    genome copies\/L for\n                    <jats:italic>S. mutans<\/jats:italic>\n                    and\n                    <jats:italic>P. gingivalis<\/jats:italic>\n                    , respectively. Detections of oral bacteria were observed in the primary and final effluent, but concentrations were significantly lower in the final effluent than in the untreated wastewater. The high levels of oral bacteria in wastewater indicated a potential transmission mechanism for these bacteria through water, specifically for\n                    <jats:italic>S. mutans<\/jats:italic>\n                    .
