Nanotechnology is most usually associated with particles smaller than 100 nanometers and nanomaterials made with nanoparticles. Approaches to toxicological testing and risk assessment for human and environmental concerns are rapidly evolving. The extent to which nanoparticle and nanomaterial toxicity can be extrapolated from existing evidence for particles and fibres is a hot topic in risk assessment. Nanotechnology research and development is quite busy around the world, and nanotechnologies are already employed in hundreds of items, such as sunscreens, cosmetics, fabrics, and sports equipment. Drug delivery, biosensors, and other medicinal applications are all being developed with nanotechnology. Nanotechnologies are also being developed for uses in the environment.

Nanotechnology is the study of objects with a diameter of less than a nanometer. Our ability to build big, intricate structures with nanoscale precision is quickly evolving, and it is made up of both top-down reductive and bottom-up additive techniques. Nature, on the other hand, has perfected a variety of nanoscale biological machinery, structures that often self-assemble due to the molecular chemistry of subunit connections. We surveied current advances in nanofabrication and biological assembly, as well as propose approaches for investigating nanoscale biological systems using super resolution microscopy. Nanotechnology employs nanosized particles and surface characteristics with extremely high surface area to volume ratios that differ from bigger particles of the same composition in terms of bioactivity, solubility, and antibacterial properties. Thus, an inverse linear analysis of particle size cannot be used to infer changes in characteristics; instead, nanomaterials must be tested in vitro and in vivo. Nanotechnology in dentistry has been focused on the production of nanoparticle fillers to improve the aesthetics of dental composites. Nanotechnology is now used in a wider range of applications.

Nanotechnology is being employed in biomimetics to create materials that facilitate hard tissue remineralization. Biomimetic materials and processes imitate natural processes, such as component self-assembly to produce, replace, or repair oral tissues.

Nanoparticles are utilised to change dental implant surfaces to influence the host response at the cellular and tissue levels for dental implants and related devices. The techniques utilised to generate nanotextured, thin-film, biocompatible coatings for implant surfaces include electrophoretic sol-gel fabrication, pulsed laser deposition, sputter coating, and ion-beam–assisted deposition. To optimise the interaction with the surrounding apical tissue, these technologies minimise the thickness of the coating layer and increase the specific surface area and reactivity.
Metals, such as silver and ceramic powders, such as silica and titanium dioxide, are important nanoparticles. In situ–generated silver nanoparticles have been shown to be highly successful in preventing a variety of biofilm-forming bacteria in restorative resins, bonding resins, and prosthetic resins while not interfering with manipulation, curing, mechanical qualities, or other performance properties. From toothpastes to composites, silica nanoparticles are already widely used in dentistry. Titania nanoparticles are commonly utilised in dental materials as colours, however they lack the antibacterial properties of Ag.

Another nanotechnology that was just introduced destroys bacteria on contact with repair surfaces. The Infinix flowable composite, which contains quaternary ammonium bound to silica, was found to dramatically reduce Enterococcus faecalis on the material's surface without compromising the composite's flexural strength, radiopacity, depth of cure, water sorption, or water solubility.
