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 don't think these teeth would kill off all the bacteria in the mouth. It would just prevent them from adhering to the tooth itself to cause trouble.
