Scientists develop better alternative to fillings

16th June 2014

A new treatment called Electrically Accelerated and Enhanced Remineralisation (EAER), has been developed at King's College London.

dentaltoolsThis new process works by repairing the teeth rather than filling in the gaps caused by tooth decay. This could potentially signal the end to a painful procedure and improve dental healthcare.

Old process

Tooth decay is currently removed by dentists with drills and the cavity is then filled with a material such as amalgam.

However, EAER accelerates the natural movement of calcium and phosphate minerals into the damaged tooth.

Prof Nigel Pitts, from King's College London Dental Institute, said: "The way we treat teeth today is not ideal. When we repair a tooth by putting in a filling, that tooth enters a cycle of drilling and refilling as, ultimately, each 'repair' fails."
