<p>Dental oncology, a vital branch of special care dentistry, addresses the oral health needs of patients undergoing cancer treatment. This narrative review explores the critical role of dentists specializing in cancer care, known as "onco-dentists," in managing the unique oral complications caused by cancer therapies, including chemotherapy, radiation therapy, and surgery. These treatments often lead to a range of oral health issues, such as mucositis, xerostomia, dental caries, periodontal disease, and trismus, significantly impacting a patient's quality of life and potentially disrupting cancer care. By providing tailored preventive and therapeutic interventions, onco-dentists enhance treatment outcomes and improve overall patient well-being. Furthermore, their collaboration with oncologists and other healthcare professionals promotes integrated care plans that address both cancer treatment and oral health management, emphasizing the importance of a holistic approach to patient care. This review aims to highlight the multifaceted role of onco-dentists, the significance of interdisciplinary collaboration, and the necessity of proactive oral health management in comprehensive cancer care. Moreover, the review underscores the importance of education at multiple levels—integrating dental oncology into medical and dental curricula, raising public awareness, and providing patient education to empower individuals in managing their oral health during cancer treatment.</p>
