Does dementia start in the mouth?

A number of studies in which the brain tissue of people who have died of dementia have revealed the presence of microbial species such as Porphyromonas gingivalis, Fusobacterium nucleatum, and Tannerella forsythia--all oral microbes. This is an example of translocation, i.e., the migration of microbes from one body site to another. But does this cause or accelerate dementia? This remains an unsettled issue. 

However, if you have had an oral microbiome test and you have one or more of these species in your mouth, should you eradicate it? Dental hygiene is likely not enough. For this reason, I created a homemade oral rinse using a combination of the fatty acid derivative, monolaurin, with the essential oil from peppermint that is intended for short-term use:

Monolaurin Oral Rinse
This recipe yields a 2% monolaurin solution. The inclusion of peppermint essential oil adds additional antimicrobial effects. 

Makes 100 ml (3.5 ounces)

2000 mg monolaurin (powder or liquid)
70 ml filtered water
30 ml glycerol liquid
4 drops peppermint essential oil

In clean glass container, combine monolaurin, water, glycerol, and peppermint. Cap and shake. Be sure to shake prior to use. 

Rinse, then spit (do not swallow), for 10 minutes once per day for no more than 14 days.
