This gel can regrow your teeth's enamel

Technology Nov 08, 2025

Scientists at the University of Nottingham have made a protein gel that can actually regrow tooth enamel—no fluoride needed.
Just like regular fluoride treatments, this gel fills in cracks and defects, helping teeth repair themselves.

How the gel works

The gel acts like a scaffold, guiding minerals from your saliva to rebuild enamel through a natural process.
It even forms an enamel-like layer on sensitive spots, which could mean less pain and better protection for your teeth.

Why this matters

Enamel loss is super common and can't fix itself, often leading to cavities or fillings.
This new gel could be a game-changer for dental care—offering an easy way to keep teeth strong and healthy for the long haul.
