Whether you know it or not, you may have already experienced the fruits of nanotechnology while trapped in the dentist’s chair. Yet, in a new review of nanodentistry, one team of scientists say the nano-evolution has just begun. Next-generation dental materials will help your teeth self-heal, rebuild your enamel, and may even protect against bacterial infections.
“Recent developments in nanomaterials and nanotechnology have improved and will further advance dentistry and oral health care in the near future,” wrote the team of Brazilian and Spanish researchers. “Nevertheless, great challenges involving ethics and safety regulations, as well as cost-effectiveness, need to be addressed and overcome before new nano-based dental materials are introduced in the market.”
