Scientists developed and created prosthetic teeth that can kill bacteria upon contact without posing any issues to the human. Using a 3D-printer, the teeth were made with a type of antimicrobial plastic that is positively charged to kill any negatively charged bacteria.

Many prosthetic teeth are vulnerable to damage and bacteria, making this scientific development a breakthrough in dentistry. The bacteria-fighting teeth will be more durable and longer-lasting than regular false teeth, saving people time and money.

This material could also be used in things like braces or retainers in the future, preventing damage and prolonging wear of the expensive dental gear. The fact that these dental implants can be 3D-printed also means they can be made quickly, easily and inexpensively.
