Researchers have recently come up with a way to make a decayed tooth repair itself with a 2-step process. First, the damaged enamel is prepared for regeneration. After that, a small electrical current pushes the appropriate amount of calcium and phosphate minerals to the tooth, painlessly repairing the decay. This eliminates the need to drill into a tooth, as well as decreasing pain injections and administering amalgam or composite fillings.
The process was developed at King?s College London and has been named EAER, or Electrically Accelerated and Enhanced Remineralisation. The need was created not only for those who dislike receiving oral care, but also to eliminate the ?drill and fill? method currently used for cavities.
?The way we treat teeth today is not ideal,? Professor Nigel Pitts said about the new form of treatment. ?When we repair a tooth by putting in a filling, that tooth enters a cycle of drilling and re-filling as, ultimately, each repair fails. Not only is our device kinder to the patient and better for their teeth, but it?s expected to be at least as cost-effective as current dental treatments. Along with fighting tooth decay, our device can also be used to whiten teeth.?
EAER is not expected to hit the market for commercial use for another 3 years or so. Reminova, a company located in Perth, has been created and is beginning to accept private investment for the oral regeneration technology.
