Robot dentist: nanotechnology dental innovations

Scientists from the Indian Institute of Science developed nano-sized robots that clean hard-to-reach areas of the teeth and kill bacteria with heat.

The spiral-shaped material is made of silicon dioxide, coated with iron.  The iron coating enables the nanobots to be controlled by a magnetic field and taken up to 2,000 micrometers deep during a tooth operation.  Being penetrated deep into the dentinal tubules of a tooth, the tool is adjusted to generate heat and kill bacteria.  The tiny bots are then retrieved from the tooth once the operation is done.

These nanobots can help increase the success of root canal treatments since current techniques are not efficient enough to go deep in the tooth and kill the bacteria.
