Canadian scientists develop fillings with antibiotic nanoparticles. Such fillings are able to protect the tooth from caries throughout life.. Previous developments did not give such a long-lasting effect, and the antibiotic was quickly washed out..

Ben Hutton from the University of Toronto spoke about the principle of the miracle filling. Chemists have calculated the optimal ratio of antibiotic and silicon in the filling so that the medicine works for years, and does not wash out almost immediately.

Previous developments allowed the antibiotic to be placed only on the surface of the filling.. Now, thanks to the new technology, the drug gets into the nanoparticles already in the assembly process, and not after it.. Thus, the amount of antibiotic in the filling increases by 50 times and slows down the process of its washing out..

According to the results of the first experiments, the antibiotic, which is part of the filling, destroys streptococci, which provoke the development of caries, even after two years.
