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.

    Yeah, but then you can bite people without infecting them.

    that is if they would even have children in the first place, why would they, if they are going to live forever

    I didn't have kids because I'm going to die someday, I had kids because I wanted someone else to do the dishes.
