Researchers at the University of Leeds have developed a paste that is painted on to the teeth and can protect against decay
Researchers at the University of Leeds have developed a paste that is painted on to the teeth and can protect against decay.
The paste contains naturally occurring molecules — peptides — which seep into the tiny holes in the tooth’s surface.
The peptides form a gel that provides a ‘scaffold’ that attracts calcium from saliva. The calcium provides a protective layer.
The paste was originally developed for treating early decay.
‘We already knew the formula could provide a certain degree of repair with tooth decay,’ says Professor Jennifer Kirkham, of the university’s school of dentistry.
‘However, we could also see that, in a paste or fluid, it could protect against acid attack.’
