The bacteria are the most numerous: there are 100 million in every millilitre of saliva and more than 600 different species in the mouth. Scientists studied healthy tissue as well as tumours in the mouth and found three strains of bacteria called Prevotella that could not be identified.
The dark, wet, and warm environment of the mouth, with the occasional meal running through it, makes it an excellent niche for microbes to live. Over the past 40 years, scientists have been arduously working to discover the over 500 different species of bacteria in and around the mouth known today. The mouth is comprised of an oral cavity, which includes the teeth and gums, surrounded by the lips, cheeks, tongue, palate, and throat.
