Dr. Rodrigo França is looking to strengthen teeth from the inside out and maintain enamel longer, using microscopic nanoparticles.
CTV: Nanoparticles may prevent tooth decay
A University of Manitoba professor is developing a better way to keep teeth healthier longer using nanoparticles

“Nano-particles are very small particles that are used for many years for many areas in medicine,” França said.
There are about 100 atoms in one nanoparticle, França said. Meaning one nanoparticle is about 4,000 times smaller than a human hair.
“When for example acids from other bacteria come, the tooth will be prepared to defend itself,” he said.
França said the particles will be attracted into the tooth’s centre using a magnetic field, travelling through tiny tubules that already exist in teeth.
