Dentistry is concerned with the protection, assessment, and therapy of a wide range of illnesses, disorders, and diseases that affect the teeth, gums, and facial (jaw and facial) region of the body. Dentists provide services for oral care and tooth health in general. Dentistry should ideally be preventative. To promote optimum dental hygiene and functionality, the Indian Dental Association (IDA) suggests that you visit your dentist regularly (at least once every six months). Regular dental examinations and oral care help avoid the onset of major dental disorders that necessitate expensive treatment.
