3D-Printed Teeth Can Kill 99% of Dental Bacteria (thestack.com)
An anonymous reader writes: A research group in the Netherlands has developed a new plastic resin that can destroy most dental bacteria when used for the creation of dental appliances via 3D-printing. The process involves embedding antimicrobial quaternary ammonium salts inside extant dental resin polymers. Since the salts are positively charged, these disrupt negatively-charged bacterial membranes. The process is also being mooted for use in the creation of knee arthroplasties, and in the manufacture of children's toys and food packaging.
I think by the time you *need* printed teeth, the bacteria pretty much has done its thing.
Ah yes, another wonderful example of god's amazing "Intelligent Design" in all its glory...teeth that inevitably decay, even with careful, meticulous daily maintenance.
Left to themselves they quickly become rotten and infected and kill you.
Stand in awe of the Wonders Of His Ineffable and Mysterious Plan!
