From edible microrobot teeth cleaners to regenerating your teeth with a drug, the future of dentistry is poised to change

Imagine a world where you could regenerate a missing tooth with a single drug, and microrobots clean your teeth every night.

That future is getting closer, scientists say. “We are really looking for disruptive technology,” says Dr. Hyun (Michel) Koo, co-founding director of the Center for Innovation & Precision Dentistry at the University of Pennsylvania.

Teeth-cleaning microrobots
A swarm of microrobots could clean your teeth for you. These nanoparticles are approved by the Food and Drug Administration for uses ranging from imaging to food coloring, thanks to their ability to take on a red, yellow or brown shade.

“You can eat them,” Koo says.

Mouth bacteria as medicine
One person’s mouth bacteria might be another’s medicine. That is the idea behind oral microbiota transplants: transfers of bacteria from the mouth of a healthy donor to a patient. Scientists at Pennsylvania State University and the University of Adelaide believe this treatment could one day curb tooth decay and gum disease.

Red-light therapy for your gums
Imagine a tooth implant with built-in technology to deliver immune-boosting red-light therapy. It doesn’t even need a battery—the light is powered by the movements of your mouth.

Rebuilding enamel
Can scientists engineer stronger, less sensitive teeth?
