Your oral health is driven by your oral microbiome

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.

Your oral microbiome impacts your overall health
Oral bacteria are associated with a range of systemic and chronic conditions including:
