The Oral Biofilm

A study published in the Journal of Pathology, Microbiology, and Immunology revealed that the average human mouth harbours more than 700 species of bacteria. These bacteria typically don't exist as single cells but instead live in communities known as biofilms. The oral biofilm is a thick and sticky layer that covers the teeth, gums, and tongue, appearing as a white, yellow, or tan coating on the tongue. If left unremoved, the biofilm matures, resulting in a complex of pathogenic bacteria that leads to oral health issues such as caries, gingivitis, and periodontitis.

Which bacteria are harmful in the oral biofilm?

It is worth noting that when the mouth is cleaned regularly and effectively, the oral biofilm and its population of bacteria are typically harmless. However, when left, they can lead to dental diseases and serious health complications.

Some of the harmful bacteria that can be found in biofilms include Fusobacterium, Streptococcus, Prevotella and Porphyromonas.
