The Father of Biohacking
The mouth is home to the second largest microbiome in your body with trillions of microbes, some beneficial and others harmful.
Each individual has between 100 - 200 bacterial species in their mouth on average, and factors like nutrition & hygiene determine which species you have.
Most oral diseases and conditions are caused by an overabundance of harmful microbes.
