Nanotechnology in Dentistry

Nanotechnology is a field of study that deals with constructing things on the scale of atoms and molecules. Scientist Dr. Richard Feynman introduced engineering at atomic and molecular levels at a lecture. It became popular and thus academic and research interest in this field increased. But what does that have to do with dentistry?

Let’s take a look:

  • Dentin Hypersensitivity – Dental nanorobots have the ability to select and block dentinal tubules (dentinal tubules are found in the very small canals of dentin which is an inner part of a tooth). The point is to reduce hypersensitivity, and dentin hypersensitivity can cause discomfort and pain when you consume cold, sweet, hot or acidic foods and drinks.
  • Dentifrobots – Dentifrobots are the tiny little robots, nanorobots, that clean organic residue by moving around teeth tissue at a mind-boggling speed. It also can identify harmful bacteria in plague and eliminate it.  One of the fantastic things is it can be deactivated immediately when accidentally swallowed by the patient, reducing the health risk.
  • Nanorobotic Local Anesthetics – Imagine controlled anesthesia for your teeth. Nanorobots are incorporated in anesthetic molecules, traveling to the pulp of the teeth, temporarily deactivating its neurosensory sensations. The dentist can signal the anesthesia to activate or deactivate and select which teeth to shut down. This can help patients’ dental anxiety and provide more comfort, as well as greater control of the anesthesia.

Pretty cool, huh? Well maybe not for everyone, but like we’ve said before, any dental innovation is interesting to us!
