Nanodentistry is a good approach to assess onset or progress of oral diseases and to identify the targets for their treatment. Using nanocharacterization tools, various oral diseases can be understood at molecular and cellular levels. It can be used to design the biocompatible, microbe resistant dental materials and implants. This nano technology will make possible the maintenance of oral health by using nanomaterials in dentistry. Nanodentistry is developing very fast and is set to transform the dentistry in a huge way.
