Abstract Nanodiamonds (NDs) are utilized for various purposes in dentistry, such as tissue regeneration, gene therapy, and medication delivery. Despite the examination of their potential for dental uses, there is currently no published review summarizing the conducted investigations. Additional investigations are required to comprehend the biological compatibility of NDs in dentistry. NDs have been proven effective for a variety of applications in dentistry because of unique qualities such as target cell selectivity, nanometer size, and fluorescence. Nanodiamonds find various applications in dentistry, encompassing roles in directed tissue regeneration, reinforcing polymers, and administering medications for treating infections and cancer. Researchers have also suggested the potential use of nanodiamonds as coatings for antibacterial or bioactive dental implants. Nevertheless, investigations on their biological compatibility have been scarce and insufficient so far, necessitating significantly further studies to envision the potential use of NDs in dentistry. It is believed that within the ten years to come, these emerging substances will discover several kinds of daily usage in dental practice.
