Oral Microbiome

Improving the microbiome environment is presented as a way to influence gum health and help stop recession. Two pieces of potassium nitrate chewing gum per day for four days can meaningfully shift the oral microbiome toward a more nitrate-reducing phenotype. Prior literature on the oral microbiome focused narrowly on Alzheimer's disease, non-communicable diseases broadly, or cancer prediction, rather than covering all three major geriatric syndromes together. No prior systematic or scoping review has mapped the oral microbiome's role across frailty, sarcopenia, and neurocognitive disorders together. The oral microbiome has attracted interest as a potentially modifiable factor in the onset and progression of geriatric syndromes, though the research base remains nascent and poorly mapped. Emerging but limited evidence links oral microbial diversity to overall health and frailty status, specific oral bacteria to cognitive decline, and poor oral health to reduced muscle function in older adults. The term 'human microbiome' was coined in the 2000s and refers collectively to all microbes within and on the human body. The oral microbiome is necessary for nitrate-to-nitrite conversion in…
