Oral health means more than just an attractive smile. Poor oral health and untreated oral diseases and conditions can have a significant impact on quality of life. And in many cases, the condition of the mouth mirrors the condition of the body as a whole. Recent reports indicate a relationship between periodontal (gum) disease and stroke, heart disease and preterm low-birth-weight babies. Likewise, more than 90 percent of all systemic diseases have oral manifestations, meaning your dentist may be the first health care provider to diagnose a health problem.
