Dental treatment uses industrial coating to fight tooth decay

Developed by researchers at Queen Mary University of London (Queen Mary), Varnish VLC is designed to combat tooth decay and acid erosion caused by everyday habits, particularly in children.

Key to Varnish VLC is flake glass technology, which protects against moisture and other harsh elements. It has been used in the maintenance of steel bridges, including the Forth Bridge, providing up to 25 years of protection before requiring major maintenance.

According to Queen Mary, this is the first time scientists have adapted this technology to create this novel treatment for tooth decay. Varnish VLC mimics the natural properties of enamel, offering an effective way to reduce wear and prevent damage.

In a statement, research lead Dr Saroash Shahid, Reader in Dental Biomaterials at Queen Mary, said: “It might sound unusual, but the challenges are similar: both teeth and bridges are exposed to harsh conditions, both suffer from corrosion, and both are difficult to protect. This project shows the power of looking outside of traditional fields for inspiration.”
