This gel can regrow your lost tooth enamel

Technology Nov 05, 2025

Big news for anyone who's ever worried about their teeth: scientists at the University of Nottingham, along with international researchers, have created a gel that can actually help regrow lost enamel.
The gel uses minerals from your own saliva to rebuild the tooth's protective layer—something current dental treatments just can't do.

Gel could change the way we deal with cavities

In lab tests, the gel restored strength to damaged teeth by forming new crystals that fused right into natural enamel, making them tougher against wear and acid.
While it's not ready for dentists' offices just yet, this breakthrough could seriously change how we deal with cavities and enamel loss in the future.
