Scientists have developed a new pain-free filling that allows cavities to be repaired 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 the repair site. It could be available within three years.

I'll have to get my teeth out of the cup in the cupboard, I had got them when they were pulled, and get them fixed up. I still have dental on my insurance even though I do not have teeth.

It will not happen for a long time, or will be very expensive or not used. Dentists are very happy with the current system, patching up, not repairing. Like painting directly over rust, it looks good but not for a very long time.
In another words they would not be making enough money.
"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."
A spinout company, Reminova, has been set up to commercialise the research. Based in Perth, Scotland, it is in the process of seeking private investment to develop EAER.

Three years my arse...
I remember hearing about similar dental innovations decades ago on Tomorrow's World.
Guaranteed I'll be dead buried and forgotten and this news item will mysteriously reappear in some magazine or other.
Just science porn.
