Dental materials are essential in modern dentistry, facilitating the diagnosis, treatment, and prevention of oral diseases. They are utilized in restorative, prosthetic, preventive, endodontic, and orthodontic procedures, with selection guided by mechanical, biological, chemical, and aesthetic properties. Innovations in nanotechnology, bioactive compounds, and digital dentistry have greatly enhanced both functional and aesthetic outcomes. This review explores the classification, properties, and recent innovations in dental materials. It examines restorative materials like composites, amalgams, and glass ionomer cements used for tooth repair and caries prevention. Prosthetic materials, including metals, ceramics, and polymers, are analyzed for their roles in fabricating crowns, bridges, and dentures. Additionally, impression materials, endodontic substances, and orthodontic wires are reviewed for their contributions to diagnostic and therapeutic procedures. Key material properties, such as biocompatibility, mechanical strength, and adhesive bonding, are critical in determining clinical performance and longevity. Emerging technologies, including nanohybrid composites, bioactive glass and CAD/CAM systems are revolutionizing dental care by enhancing precision, durability, and patient-specific customization. The incorporation of bioactive compounds has further introduced materials capable of tissue regeneration and disease prevention, aligning with minimally invasive and regenerative dentistry goals. Technological advancements continue to drive innovation in dental materials, improving patient outcomes and treatment efficiency. Understanding the classification, properties, and developments in dental materials is essential for clinicians and researchers striving for enhanced performance in restorative, prosthetic, and diagnostic applications. Future progress is expected to integrate smart, bioactive, and digitally designed materials, advancing patient-centered dental care.
