New Tooth Cavity Protection: Nanoparticles Make Surface Too Slippery For Bacteria To Adhere
Researchers adopted polishing technology used in the semiconductor industry (chemical mechanical planarization) to polish the surface of human teeth down to nanoscale roughness. Roughness left on the tooth after the polishing is just a few nanometers, which is one-billionth of a meter or about 100,000 times smaller than a grain of sand.
Sokolov and Gaikwad showed that teeth polished in this way become too “slippery†for the “bad” bacteria that is responsible for the destruction of dental enamel. As a result the bacteria can be removed fairly easily before they cause damage to the enamel.
Yes we’re all going to die, nano-particles are going to destroy all life including bacteria.
