1 Amyloidosis
2 Does tooth bacteria cause Alzheimer’s?
Who knows? I am not sure how settled this research is, but it could really incentivize dental hygiene.
Gingivitis destroys your brain, according to this pop science article and its many journal references, by enabling P. Gingivalis buildup and eventual brain damage through the “gingipains” they produce.
PR about Melbourne research into gingivitis vaccines.
This company gets some free publicity for their anti-gingipain drugs.
Sanctimonious but sensible article about how to brush your teeth to minimise this nastiness.
