The Salivary microbiome is the nonpathogenic, commensal bacteria present in the healthy human salivary glands. It is distinct from bacteria that may cause infection in the glands. It differs from the oral microbiome which is located in the oral cavity. Oral microorganisms tend to adhere to teeth. The oral microbiome possesses its own characteristic microorganisms found there. Resident microbes of the mouth adhere to the teeth and gums. "[T]here may be important interactions between the saliva microbiome and other microbiomes in the human body, in particular, that of the intestinal tract."
