Dentistry, also known as dental or oral medicine, is the branch of medicine concerned with teeth, gums and the mouth. It studies, diagnoses, prevents and treats diseases, disorders and conditions of the oral cavity, focusing on the development and arrangement of teeth and oral mucosa. Dentistry can also include aspects of the craniofacial complex, such as the temporomandibular joint, and the primary professional is the dentist.
Treatments are carried out by dental teams comprising the dentist, assistants, hygienists, technicians and dental therapists. Most operate in private practices, clinics or dedicated facilities, while the modern evidence-based approach requires high-quality scientific research to guide every clinical decision: from prevention with fluoride prophylaxis to the management of conditions such as caries, periodontitis or systemic diseases involving the oral cavity.
Key tools include oral radiology, haematological tests to prevent surgical complications and protocols shared with cardiologists or other specialists in at-risk patients. According to the World Health Organisation, oral diseases are a global public health problem because they disproportionately affect more socioeconomically vulnerable groups. This is why most therapies aim to prevent or treat caries and periodontitis with restorations, surgical extractions, scaling, root planing, endodontic and aesthetic treatments.
