## Summary & Core Narrative
Bacteria can grow in the tiny gap between a tooth and its filling, causing infection and damaging the restoration. During graduate research at U of T, Cameron Stewart formed porous silica particles around an antimicrobial so it could be released slowly near a filling. That work became the basis of Mesosil.

The company secured FDA 510(k) clearance by supplying its technology to established dental companies rather than selling directly to dentists. Mesosil raised $2.3 million in 2024 and maintains research ties with U of T. Stewart is now considering how to increase production, potentially through a small chemical manufacturing facility, while exploring other applications.

## Key Takeaway
