Mesosil develops antimicrobial additives for bacteria-prone dental restorations
Mesosil is developing a dental-materials business around a small ingredient rather than a finished treatment. Its antimicrobial silica additive is intended for manufacturers that make products dentists already use to restore teeth. That supplier model could put Mesosil’s technology into a manufacturer’s existing product without requiring dentists to adopt a separate treatment.
An ingredient, not a separate treatment
Bacteria can accumulate around the boundary between a filling and a tooth, contributing to recurrent decay and damage to the restoration. Mesosil markets its Mesosil 500 additive for restorative materials that address this problem.
The University of Toronto’s Faculty of Dentistry reports that Mesosil chose to supply technology and additives to established dental companies rather than sell directly to dentists. In 2026, BetaKit reported that the technology was integrated into an unnamed client’s dental products.
Building the material into a product
Mesosil makes its particles by assembling a drug and silica together into a porous structure. The company offers different particle sizes and says the surface and surrounding matrix can be customized for a manufacturer’s formulation.
The particles are designed to release antimicrobial agents over time. Mesosil says they can be mixed into existing polymer and composite materials during manufacturing, and it offers development support to product makers.
