BioMin

Founded by Prof Robert Hill and Prof David Gillam, BioMin toothpaste uses a specialist bioglass formulation which binds to the teeth and provides controlled release of low-level fluoride and an optimal concentration of calcium and phosphate mineral ions over a twelve-hour period.

The extra fine particles block the tiny dentinal tubules which lead to the nerve to tackle sensitivity and strengthen the enamel. Meanwhile, smart pH technology reacts quickly to food and drink, neutralising acidity and reducing the risk of decay. A clinical trial found BioMin reduces sensitivity by up to 90% in just one month, beating market leaders.

In 2024, BioMin was the active ingredient in products used by three million consumers in over thirty countries. As well as BioMin toothpaste, the bioactive glass technology is also licensed for use in other dental products. The spinout raised £1.5m from Group Pharmaceuticals in 2026 to fund the next stage of growth.
