The mouth,
finally
modeled.
ZERObrush replaces the manual toothbrush with a custom-fit mouthpiece and an AI layer that grows with every session. IRB-certified clinical data, FDA clarity, and a contract manufacturer already on board.
One data layer.
Many indications.
Every user starts with a digital impression. The AI generates a custom mouthpiece engineered to their dentition — no technician loop. Each session deepens the model.
Oral Digital Twin
A longitudinal model of the user’s oral health, refined over time. The same twin unlocks the full product line — retainers, whitening, diagnostics — on one data layer.
AI-Generated Custom Mouthpiece
Engineered to each user’s exact dentition. No lab, no technician. On-demand 3D printing with a contract manufacturer already onboarded.
Subscription Economics
Razor-and-blade model: one-time device + recurring mouthpiece refills. Per-unit economics validated. Path to ~70% gross margin at scale.
The data speaks for itself.
The platform monitors and adapts to real time clinical noise conditions, enhances clinician focus and communication, improves patient experience, and integrates into existing clinical workflows.
