Fillings Could be a Thing of the Past: New Dental Treatment Revealed

New technology in the dental field will give patients an all new reason to smile. Scientists in London have unveiled new pain-free, self-repairing fillings to treat tooth decay.

What's the Latest?

Despite the amazing things a dentist can do for your smile, visits to his/her office are often accompanied with a frown. According to The Guardian, patients may have a new, pain-free reason to smile. An advanced new treatment called Electrically Accelerated and Enhanced Remineralisation (EAER) revolutionizes the way cavities are filled and could become available within three years. Unlike the current process of clearing decay and filling cavities with resin, EAER utilizes an electric current to expedite "the natural movement of calcium and phosphate minerals into the damaged tooth."

What's the Big Idea?

While patients will certainly be thinking of how much pain the new process can save them, EAER has potential financial benefits as well. The Guardian interviewed Professor Nigel Pitts of King's College London's Dental Institute, who explained the many future positives he predicts EAER will net:

"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.

"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."

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
