Tooth decay begins when acid produced by bacteria in plaque dissolves the mineral in the teeth, causing microscopic holes or “pores” to form. As the decay process progresses the micro-pores increase in size and number to the point that eventually the damaged tooth may have to be drilled and filled, or even removed.
“This may sound too good to be true, but we are essentially helping acid-damaged teeth to regenerate themselves. It is a totally natural non-surgical repair process and is entirely pain-free too,” says Jennifer Kirkham, a professor at the University of Leeds Dental Institute.
Researchers led by Amalia Aggeli designed the fluid that contains a P 11-4, a peptide that will assemble together into fibers under certain conditions. In practice, this means that when applied to the tooth, the fluid seeps into the micro-pores caused by acid attack and spontaneously forms a gel.
