Dentistry is the specialized branch of medicine concerned with the diagnosis, prevention, and treatment of diseases and conditions affecting the teeth, gums, and supporting oral structures. The field requires comprehensive knowledge of oral anatomy, microbiology, and biomaterials to understand the complex physiological processes involved in mastication and oral health. Modern practice encompasses a wide range of interventions, including preventative care, which focuses on maintaining tissue integrity, and restorative procedures designed to repair damaged tooth structure. Advanced techniques utilize specialized imaging and materials science to address conditions such as periodontal disease, enamel erosion, and malocclusion, thereby aiming to preserve both the function and the aesthetic appearance of the mouth.
