Micronutrients in Oral Health

Oral health is inseparably linked with nutrition, and among the key dietary factors, micronutrients play a vital role in the development, maintenance, and repair of oral tissues. Vitamins, minerals, and antioxidants, though required in small amounts, exert powerful effects on enamel formation, periodontal health, mucosal integrity, immune defense, and overall oral well-being. Inadequate intake or imbalance of micronutrients has been associated with a wide range of oral conditions, including dental caries, periodontal disease, oral mucosal lesions, delayed healing, and increased susceptibility to infections. Conditions such as zinc deficiency, fluorosis, oral lichen planus, oral cancer, and anemia further illustrate the profound clinical consequences of nutritional deficiencies or excesses. On the other hand, optimal nutrition and targeted supplementation open promising avenues for prevention and management in dentistry. This book, “Micronutrients in Oral Health”, has been prepared to bridge the gap between nutritional science and oral health care. It brings together fundamental concepts, clinical evidence, and applied perspectives to highlight the indispensable role of micronutrients in maintaining a healthy oral cavity. . The chapters have been carefully structured to provide readers with a comprehensive perspective on the role of micronutrients in oral health. Our aim is to provide a comprehensive, accessible, and practical resource that will serve as a guide for dental professionals, nutritionists, researchers, and students who wish to deepen their understanding of this vital subject. We hope that this volume will not only contribute to academic knowledge but also inspire greater emphasis on preventive, nutrition-based strategies in oral health care.
