Preventive and Community Dentistry serves as the cornerstone of oral health, focusing on proactive measures to maintain healthy teeth and gums. This field emphasizes education, early intervention, and regular dental care to prevent oral diseases such as cavities, gum infections, and tooth loss. Community dentistry extends these practices to underserved populations, promoting public health initiatives like fluoridation programs and school-based dental check-ups. By fostering awareness and encouraging good oral hygiene habits, this branch of dentistry reduces the prevalence of oral health issues and bridges healthcare disparities. Collaboration among dental professionals, educators, and community leaders ensures widespread access to preventive measures, leading to healthier communities and brighter smiles for everyone.
