3D Printed Teeth Could Fight Bacteria

Researchers in the Netherlands are making dental implants that kill microbes that settle on them.

The researchers printed teeth with and without antimicrobial properties to test their material. They then put tooth decay-causing bacteria on the samples. More than 99 percent of the bacteria died on the treated teeth, while only about 1 percent were killed on the untreated ones.

According to the World Health Organization, poor oral health is tied to “poor living conditions, low education, and lack of traditions.” Some 26 percent of adults have untreated tooth decay. It’s particularly prevalent in low income populations, and it’s been linked to a whole host of health issues, including heart disease, stroke, diabetes, pneumonia, poor pregnancy outcomes and dementia.
