Fillings which REPAIR tooth decay and protect against further cavities 'will revolutionise dentistry'
Fillings which help teeth to self-repair from ongoing decay have been invented by scientists.
Hailed as a revolution in dental care, the compound - known as bioactive glass - not only blocks cavities but repairs bacterial damage.
It releases minerals such as calcium and phosphate, which the tooth uses to replace what was lost during the decay and repair itself.
The technology, developed by experts at Queen Mary University of London, is set to do away with the need for mercury fillings, experts hope.
Unlike existing fillings, the new compound has almost no risk of falling out.
