A team of researchers at the University of Leeds' School of Chemistry is developing a pain-free method to combat cavities.
The technique uses a fluid called P 11-4 that has a fibre-like peptide. When the fluid is applied to a damaged tooth, it fills the tooth's cavities and forms a gel matrix that attracts calcium.
Slowly, this matrix will rebuild the damaged part of the tooth. Best of all, there's no Novocaine, no drilling and no maniacal dentists involved. [GizMag]
