Evidence grows that oral health is strongly linked to overall health

"The eyes may be the window to the soul, but the mouth provides an even better view of the body as a whole," The Wall Street Journal's Melinda Beck writes in her Health Journal column. "Some of the earliest signs of diabetes, cancer, pregnancy, immune disorders, hormone imbalances and drug issues show up in the gums, teeth and tongue—sometimes long before a patient knows anything is wrong. There's also growing evidence that oral health problems, particularly gum disease, can harm a patient's general health as well, raising the risk of diabetes, heart disease, stroke, pneumonia and pregnancy complications."
