Periodontal Disease (tooth and gum disease linked to the oral microbiome) causes brain inflammation linked to neurodegenerative disease.
Other studies have shown links with multiple gut illnesses hence the need to get your oral hygiene good. (not fluoride based products and alcohol based mouth washes)
These results suggest that the periodontal inflammation-induced expression of IL-6 is related to neuroinflammation and BBB disruption in the hippocampus, ultimately leading to cognitive impairment.
Periodontal therapy may protect against neurodegenerative diseases.
