A LIVING GATEWAY
The Mouth
Beyond function and anatomy, the mouth becomes a place to consider expression, experience and the stories carried through a lifetime.

The Smile Gate explores the profound connections between the mouth, teeth, emotion, memory, identity and the wider human experience. Blending ancient wisdom with modern insight, Marc Mortiboys invites you to see the mouth in a completely new light.
THEMES WITHIN THE BOOK
