Researchers at the University of Leeds have discovered a pain-free way of tackling dental decay that reverses the damage of acid attack and re-builds teeth as new.
The peptide technology is based on knowledge of how the tooth forms in the first place and stimulates regeneration of the tooth defect.
The 'magic' fluid was designed by researchers in the University of Leeds' School of Chemistry, led by Dr Amalia Aggeli. It contains a peptide known as P 11-4 that - under certain conditions - will assemble together into fibres. In practice, this means that when applied to the tooth, the fluid seeps into the micro-pores caused by acid attack and then spontaneously forms a gel. This gel then provides a 'scaffold' or framework that attracts calcium and regenerates the tooth's mineral from within, providing a natural and pain-free repair.
In order to mold human organs from a clump of cells, Atala came up with creatively constructed scaffolds that would guide the newly grown cells into shape. In most cases — for the bladder, blood vessels and valves, for example — he uses a biodegradable material made of collagen, the structural component in skin. But in order to create more complex structures, such as the heart, he needed something far more sophisticated as a matrix. That's where the inkjet printer came in. One of Atala's colleagues had the bright idea that if a printer can spray tiny bits of ink in a pre-set pattern, why couldn't that same technique be used to scatter cells into pre-designed templates? So, instead of printing in one dimension, Atala's expert re-tooled the printer to "print" its cells in successive layers; the end result is a three-dimensional mold of cells that looks suspiciously like, for example, a rudimentary heart.

I agree i don't like fluoride either but according to science it helps re-mineralization of teeth
