What distinguishes the oral microbiome from other microbiomes in the body?

The oral microbiome is distinct from other microbiomes in the body due to its unique structure and composition. It is the second largest and most diverse microbiome, encompassing approximately 700 different species of bacteria that thrive in various environments within the mouth.

• Unlike gut microbiomes, where bacteria undergo regular turnover due to continuous movement and shedding, oral bacteria can remain unchanged unless disrupted by mechanical means like brushing.
• The varied niches within the mouth, such as the gum line and tongue surface, host different types of bacteria adapted to specific conditions.
• This diversity and the ability to have different strains lead to various health outcomes, depending on how well-balanced the microbiome is.

Thus, the unique characteristics and behaviors of the oral microbiome warrant special attention in the context of overall health.
