Over the past two decades, nanotechnology has profoundly transformed restorative dentistry by enhancing the mechanical, physical, and aesthetic properties of dental composite materials. Conventional resin composites exhibited clinical limitations, including polymerization shrinkage, marginal degradation, and inadequate resistance to occlusal forces, which often compromised long-term restorative success [1,2,3]. The integration of nanoscale fillers has improved filler distribution, filler–matrix interactions, and mechanical strength [4,5,6]. Nanofilled and nanohybrid composites demonstrate higher flexural strength, reduced polymerization shrinkage, superior wear resistance, and enhanced optical properties compared to traditional composites [6,7,8]. The small particle size contributes to improved surface polishability, gloss retention, and color stability, while functionalized and bioactive nanoparticles enable ion release for remineralization and antibacterial effects [31,32,36]. This review provides a comprehensive analysis of the role of nanotechnology in modern cosmetic dental filling materials. It covers structural classification, mechanical and physical properties, clinical performance, biocompatibility, limitations, and future perspectives. Current evidence supports improved durability, aesthetics, and oral health outcomes, making nanocomposite materials highly suitable for both anterior and posterior restorations [9,10,11].
