You have dirty tooth or lost any of your tooth, you don’t have to worry much now, as researchers have developed a 3D printed tooth that can also clean your mouth. This 3D printed tooth will clean your mouth and get rid of backteria once and for all.
Andreas Herrmann from the University of Groningen in the Netherlands and his colleagues have developed an antimicrobial plastic that can kill bacteria on contact. Talking about this Herrmann said to New Scientist, “The material can kill bacteria on contact, but on the other hand it’s not harmful to human cells,”
This 3D printed tooth works by mixing antimicrobial ammonium salts with usual dental resin polymers. The salts used is positively charged, which disturb the negatively charged bacterial membranes that leads bacteria to burst. Researchers developed this artificial tooth by using 3D printer. Researchers created the replacement teeth, orthodontic braces and some others by putting the mixed material to 3D printer.
It killed more than 99 percent of the bacteria that causes tooth decay in the testing process. But this test was only performed in six days time period, so researchers need to do the test for longer period.
