The tooth-rebuilding technique developed at King's College London does away with fillings and instead encourages teeth to repair themselves. Tooth decay is normally removed by drilling, after which the cavity is filled with a material such as amalgam or composite resin. The new treatment, called Electrically Accelerated and Enhanced Remineralisation (EAER), accelerates the natural movement of calcium and phosphate minerals into the damaged tooth. A two-step process first prepares the damaged area of enamel, then uses a tiny electric current to push minerals into the repair site. It could be available within three years. Professor Nigel Pitts, from King's College London's 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...." (read more at link above)
