The bacteria in your mouth impacts the health of your whole body. Here's how to stay healthy from teeth to toes. Your Mouth Has a Microbiome, Too—Here Are 5 Ways to Take Care of It for Better ...
Mouth infections are most commonly caused by an overgrowth of bacteria that normally populate the oral cavity. [1] In a healthy adult, billions of bacteria, viruses, and fungi reside within the oral cavity and represent more than 500 different species. They are collectively known as the oral microbiome.
Teeth, saliva, and oral tissues are the major components of the oral environment in which the oral microbiome resides. Like most environments, some oral environments, such as teeth and saliva, are abiotic (non-living), and some are living, such as the host immune system or host mouth mucosal tissues- including gums, cheek ("buccal") and tongue (when present).
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.
The temperature and pH of saliva makes it conducive for bacteria to survive in the oral cavity. Bacteria in the oral cavity include Streptococcus mutans, Porphyromonas gingivalis, and Staphylococcus. [15] S. mutans is the main component of the oral microbiota. [15] A healthy oral microbiome decreases oral infections and promotes a healthy gut ...
It may not be that the mouth is vulnerable to the new coronavirus, but that Covid-19 may set up an immune circumstance such that other viruses such as herpes labialis — the herpes virus above ...
Bacteriophages (viruses that infect bacteria) that target S. mutans have been researched. Phages have shown promise in reducing S. mutans in lab settings, potentially offering a targeted approach to caries prevention without harming the mouth's natural microbiome.
In the neonatal period and in early childhood interaction of host immunity with the microbiome is critical. During this interaction various immunity arms are educated. They contribute to homeostasis and determine the future immune system settings, i.e. its susceptibility to infections and inflammatory diseases .
