Oral microbiota is an important part of the human microbiota. Oral microbes can be colonized into the intestine in various ways. Oral microbiota is associated with a variety of oral diseases. Recently, increasing evidence has shown that the oral microbiota is closely related to the physical state of humans, such as diabetes, obesity, and cancer. In the future, oral microbiota will become a new target for improving the physical state of humans.
