Nanoparticles to prevent tooth decay; looking to put dentists out of business

Nanoparticles to prevent tooth decay; looking to put dentists out of business

April 20, 2015

We’re never at a loss for toothpaste choices, but we may see the addition of “With Nanotechnology!” advertised on the tubes in the future. Researchers from the University of Rochester and University of Pennsylvania have designed drug-releasing nanoparticles to protect the teeth from bacterial damage and decay.
