An innovative cavity treatment designed by scientists at King's College London and announced this week may eliminate the need for drilling injections and even pain. Rather than removing decay and refilling a cavity with manmade materials Electrically Accelerated and Enhanced Remineralisation (EAER) encourages teeth to patch-up on their own. The technique reverses the decay process by fast-tracking the natural conglomeration of calcium and phosphate minerals in the tooth causing it to re-mineralize and restore its health. Along with fighting tooth decay EAER can also be used to whiten teeth according to Professor Nigel Pitts from the Dental Institute at King's
