This review provides a comprehensive overview of dental materials that promote tissue healing while exhibiting antimicrobial properties. The focus is on materials that are biocompatible, bioactive, and non-toxic to host cells, with demonstrated bacteriostatic and bactericidal activities. Current advances in natural bactericides, antimicrobial polymers, and bioactive glass/polymer composites are summarized, along with techniques employed for surface modification and the coating of dental implants. Three major categories of antimicrobial coatings were identified: antibacterial phytochemicals, synthetic antimicrobial agents (including polymers and antibiotics), and metallic nanoparticles. Bioactive coatings were further examined to identify potential antimicrobial strategies within these materials, and existing research gaps were highlighted. A systematic literature search was conducted in PubMed, Scopus, and Web of Science for articles published between January 2010 and June 2025. Overall, this review underscores the growing potential of multifunctional dental materials that integrate bioactivity with antimicrobial performance, offering promising directions for the development of next-generation restorative and implant materials.
