Public Health Dentistry (DPH) is the branch of dentistry that promotes professional oral health care by providing preventive and curative methods for oral infections to the community or population instead of handling individual patients at the clinic. Public Health Dentists responsibility is to encourage the oral health of society and generate consciousness about it within the popular of all age groups. With the increasing population, it becomes complicated to provide equal health services to the communities, and dental care is most often overlooked by people as compared to any other health inspection. 

People, especially in rural zones or impoverished areas, have a general idea that brushing teeth twice a day is the only oral care you would ever need, but it is more than that. Oral care requires proper checkups every six months, just like any separate body checkup. Lack of education and loss of understanding are the prime elements of its laxity, and to encourage this at the public level that is when Public Health Dentistry comes to the rescue.

Most of the Primary Health Dentists are primarily recruited in government background and there is more of an office work which includes gathering data and information and then working on to correct the loopholes in the public health sector.
