This review focuses on the use of state-of-the-art nanotechnology in restorative materials, presenting many innovative approaches. With an eye on improving dental caries management, our findings point to a bright future for creating novel, superior biomaterials. Dental materials have benefited from the novel use of nanotechnology, which offers the possibility of creating materials with superior qualities and antibacterial abilities. In this overview, we review the development of functional nanoparticles and their potential uses in dental restorative materials as helpful tactics for managing dental caries. Additionally, we provide an outline of the suggested remineralizing and antibacterial processes. A systematic literature review from 2000 to 2023 was performed using PubMed, Medline, and ScienceDirect databases. The keywords used were "nanotechnology," "dental caries," and "restorative material." Nanomaterials have considerable promise in reducing the formation of biofilms, blocking the demineralization procedure, remineralizing tooth structure, and fighting microorganisms linked to dental cavities. These promising findings pave the way for further clinical research to determine the restoration products constructed using nanotechnology and their therapeutic efficacy.
