Biomin Technologies, a UK-based dental additive supplier spun out from Queen Mary University of London, attracted £2m ($2.6m) on Friday in a funding round backed by toothpaste manufacturer Guangdong Kanwan Cosmetics.

The round also featured a range of unnamed investors, identified only as trade partners of Biomin.

Founded in 2014, Biomin produces toothpastes that contain bioactive glass, a material capable of replenishing worn mineral on the tooth’s surface. The technology helps alleviate tooth sensitivity and halt the progression of decay.
