, like, really strong. But when problems arise, they can also be very tough and painful. Toothaches, for example, can be total bummers by causing severe pain and sometimes even fever and headache, which make it difficult to maintain the daily routine.An artificial enamel
The team of scientists has developed a set of nano-sized cleaning robots that can clean the hard-to-reach areas deep inside dentinal tubules and kill bacteria via heat. The helically shaped material is made of silicon dioxide coated with iron, which can be controlled using a device that generates a low-intensity magnetic field,One of the problems with the current root canal treatment method is it uses chemicals to kill off the bacteria.
Earlier practices like using lasers and ultrasound to wash away the bacteria had their limitations, like being able to penetrate only about 800 micrometers into the tooth. But the new miniaturized robots provide a solution that gives an even deeper cleaning.
