Timothy Martinez DMD suggests that,  Primary oral health care refers to the range of preventive and basic dental services that promote optimal oral health and prevent dental diseases. It encompasses a broad range of activities, including health promotion, disease prevention, and diagnosing and treating dental problems.

The World Health Organization (WHO) defines primary oral health care as "the first level of care provided by a dentist or other oral health professional, which includes preventive and therapeutic care, education, and referrals for specialized services when necessary."

Primary oral health care services include routine check-ups, cleanings, fluoride treatments, sealants, and oral health education and counseling. These services are designed to prevent dental problems and detect and treat early signs of dental disease.

Preventive care is a critical component of primary oral health care. It includes measures such as regular dental check-ups and cleanings and advice on proper oral hygiene practices, such as brushing and flossing. Preventive care can help prevent tooth decay and gum disease, the most common dental problems.

In addition to preventive care, primary oral health care also includes diagnosing and treating dental problems. This can range from simple fillings and extractions to more complex procedures such as root canals and dental implants.

Oral health education and counseling are also essential to primary oral health care. Patients receive guidance on maintaining good oral health, including advice on healthy eating habits, tobacco use cessation, and protective devices such as mouthguards.

Access to primary oral health care is a critical public health issue, as dental problems can significantly impact overall health and quality of life. Poor oral health has been linked to various health problems, including heart disease, stroke, and diabetes.

In many parts of the world, access to oral health care is limited, particularly for disadvantaged and underserved populations. To address this issue, the WHO has called for integrating oral health care into primary health care systems to improve access to basic dental services and promote oral health equity.

In conclusion, primary oral health care is essential to overall health and well-being. It encompasses a range of preventive and basic dental services, as well as education and counseling, and is critical to preventing dental problems and promoting good oral health throughout life.
