The oral microbiome, mainly comprising bacteria which have developed resistance to the human immune system, has been known to impact the host for its own benefit, as seen with dental cavities. The environment present in the human mouth allows the growth of characteristic microorganisms found there.
Since bacteria that normally reside in the oral cavity cause mouth infections, proper dental hygiene can prevent most cases of infection. As such, mouth infections are more common in populations with poor access to dental care (homeless, uninsured, etc.) or populations with health-related behaviors that damage one's teeth and oral mucosa ...
Different areas of the oral cavity present different ecological niches, and each species has specific properties for colonizing different oral sites. S. mutans is most prevalent on the pits and fissures, constituting 39% of the total streptococci in the oral cavity. Fewer S. mutans bacteria are found on the buccal surface (2–9%). [7]
The oral microbiota consists of all the microorganisms that exist in the mouth. It is the second largest of the human body and made of various bacteria, viruses, fungi and protozoa. [14] These organisms play an important role in oral and overall health. Anthony Van Leeuwenhoek was the first to view these organisms using a microscope he created ...

A member of the human microbiome, Eikenella corrodens is a commensal bacterial species found in the mouth and upper respiratory tract.It is an unusual cause of infection and when it is cultured, it is most usually found mixed with other organisms.
Oral candidiasis is the most common fungal infection of the mouth, [77] and it also represents the most common opportunistic oral infection in humans. [78] Infections of the mouth occur in about 6% of babies less than a month old. [7] About 20% of those receiving chemotherapy for cancer and 20% of those with AIDS also develop the disease. [7]
Bacteria were first detected under the microscope of Dutch scientist Anton van Leeuwenhoek in the late 17th century from his own healthy human oral sample. [1] After using this technology on a healthy sample, Leeuwenhoek applied his tool to the decayed tooth matter of his wife, where he noted that the organisms present were highly similar to those found in cheese.
