Chronic bad breath
Gut inflammation

Cavities and gum disease are the most common diseases on the planet - and largely preventable.

We only see a dentist a few times per year. Only 50% of US adults regularly go!

Oral disease is diagnosed based on the presence and severity of symptoms

Late-stage detection requires invasive and expensive procedures like cavity fillings and root canals
