Researchers at the University of Leeds have created a paste that can be painted on to teeth to protect against decay.
The paste is said to contain naturally occurring molecules, peptides, which are absorped by the teeth.
The peptides create a gel that provides a ‘foundation’, attracting calcium from saliva.
The calcium builds up and provides a protective layer.
‘We already knew the formula could provide a certain degree of repair with tooth decay,’ says Professor Jennifer Kirkham, dean for research and innovation at Leeds Dental Institute.
‘However, we could also see that, in a paste or fluid, it could protect against acid attack.’
The Daily Mail Online reports this technology could be available within a year.
