About us

We’re putting the mouth at the front of everyday healthcare.

Gum disease is a public emergency. Almost half the adults over the age of 30 have some form of the disease, and inflammation from the gums opens the floodgates to a range of diseases including diabetes, CVD, and Alzheimers. We're going to change that.

What are we doing?

We’re building a new system for oral care management focused on prevention. This includes using the power of salivary diagnostics coupled with machine learning, and our own range of products to take control of the oral health crisis.


Our values


Who are we?
