DNA from another person can remain in your mouth for a short period, typically hours to a few days, depending on factors like saliva production, oral hygiene, and the mode of DNA transfer (e.g., kissing, sharing utensils). However, it generally gets cleared away through normal oral activities such as eating, drinking, and brushing teeth. In forensic contexts, trace amounts of DNA may sometimes be detected for longer, but this is not common in everyday scenarios.
