Oral Microbiome


What is the oral microbiome’s contribution to our health?

The oral microbiome refers to the community of microbes that reside in our oral cavity and is the second largest community (with over 700 kinds) that resides in/on our body [1]. The normal microbiome consists of bacteria, fungi, viruses, archaea and protozoa. Oral microbiota is now recognized to be able to engage the brain by producing metabolites that can influence the brain. The oral microbiome is known to work closely with gut microbiome, influencing conditions like IBD, liver diseases, heart diseases, metabolic diseases and cancer. The oral microbiome can be tested along with gut microbiome and may be specifically monitored to understand persistent conditions such as caries, periodontal disease and gingivitis.
