Oral health and general health and well-being are associated, with many medical conditions affecting oral health and vice versa. Oral health professionals may include dentists, dental hygienists, dental therapists and community dental health coordinators. Oral health professionals may diagnose and treat oral disease, manage patients' oral health, educate patients on good oral health behaviors and refer patients to their health care providers as needed.
