Read the full article: Electrical Current To Heal Cavities - Business Insider:

"Researchers at King's College London have developed a technique called Electrically Accelerated and Enhanced Remineralzation, in which a device they've dubbed a "healing hand piece" is placed over the site of a cavity. The tool emits a small electrical current that promotes the remineralization of the tooth, driving calcium, phosphate, and other substances back into the enamel, the scientists told the Washington Post (cavities happen when bacteria break down, or demineralize, the enamel with acid). The technique would take about as much time and cost about the same or less than a traditional filling, and publications describing the technique should be published "in coming months," they said."

I'm pleased to say that after having a mouthful of these things, I'm now down to just one amalgam. OK, so the rest of my teeth are crowns, oh well. This FDA News Release, FDA Issues Final Regulation on Dental Amalgam, reports:

• The regulation classifies dental amalgam into Class II (moderate risk). By classifying a device into Class II, the FDA can impose special controls (in addition to general controls such as good manufacturing practices that apply to all medical devices regardless of risk) to provide reasonable assurance of the safety and effectiveness of the device.
• The special controls that the FDA is imposing on dental amalgam are contained in a guidance document that contains, among other things, recommendations on performance testing, device composition, and labeling statements.

Mercury-Containing Dental Fillings - Health and Environmental Concerns

Dental amalgam. You might also know these as mercury containing dental fillings. I've got them, you've got them, we've all got them. Yesterday there was a bit of a brouhaha over them in a hearing in Washington DC, Dental Industry Gets An Earful On Mercury. The hearing considered whether dentists should be required to keep pieces of fillings from getting into public wastewater, using special equipment. In any event, the hearing created opportunities for legislators to attack the dental industry on the purported health risks of having mercury-containing fillings in your mouth, and the ramifications of mercury getting into wastewater. If you're interested in the health risk aspect of this, I recommend this page on the FDA's website, Questions and Answers on Dental Amalgam. On a personal closing note, I rotted my teeth on childhood candy, resulting in amalgams in all my teeth; thankfully now, I have a mouthful of caps and crowns, and only one remaining amalgam.
