Scientists have developed a technique that triggers the tooth’s natural repair process to reverse decay - and it could be available within three years.

The technique, developed at King’s College London, uses electrical currents to trigger minerals in the tooth to repair damage.

"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," said professor Nigel Pitts of King's College London Dental Institute in a press release.
