Scientists in London develop pain-free filling that allows teeth to repair themselves without drilling or injections 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...

Dental fillings could become a thing of the past By Laura Clout  Last Updated: 12:23am BST 05/04/2008     Dentists will one day be able to dispense with fillings and help decaying teeth repair themselves, scientists believe.Researchers say they have developed a way of regrowing dentine, the yellow mineral substance in the middle of teeth that is most affected by decay. They hope that within a decade, dentists will be able to use the technique and eliminate the need for fillings.Prof Sally Marshall, of the University of California, said the technique involves painting a calcium solution onto the damaged dentine.This...

Swedes urged to pull fillings from corpses May 19 2004 at 07:33PM Stockholm - Amalgam tooth fillings made with mercury should be pulled out before people are cremated to cut emissions of the highly toxic metal, a Swedish government agency report proposed on Wednesday. Mercury, also known as quicksilver, has been linked to neurological problems and is especially harmful to young children and foetuses. It would be "difficult from the ethical point of view, but it it is nevertheless desirable to be able to decrease the emission of quicksilver", the Chemical Inspectorate report said. It calculated that since three quarters...
