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.
