Nanomaterials are made of small particles and they have unique properties that differ from the larger bulk materials and the atomic level. The most common use of nano materials in dentistry today is in the form nanoparticles used in the composite materials. The transition to nanoparticles in dental composites has allowed for improved resistance to wear and less shrinkage all of which make the fillings better and long lasting. I use a nanoparticle composite which allows me to restore broken down teeth without any sensitivity after the treatment.
But recently other uses are starting to emerge. It has been found that small graphite particles can kill bacteria. This has been developed into a new technique to apply medication to dental plaque. As presented in the Dentistry Today journal the technique uses nanoparticles that can bind to the saliva-coated teeth within the plaque and transport the antibacterial agent to the targeted sites.
