This gel can help your teeth rebuild lost enamel

Technology Nov 11, 2025

A team from the University of Nottingham has created a protein-based gel that helps teeth rebuild their own enamel—using minerals already found in your saliva.
Unlike regular dental treatments that just prevent damage, this new gel could actually reverse it, making it a pretty big deal for anyone who dreads cavities.

Gel can handle everyday chewing

Lab tests on extracted human teeth showed the gel forms a tough new layer and even protects sensitive areas.
The researchers say the enamel it builds can handle everyday chewing.
Human trials are set for next year, and if all goes well, startup Mintech-Bio is looking to commercialize the gel.
