Poor oral health can have a profound impact on both the short- and long-term health of an individual. Left untreated, extensive tooth decay and the resulting pain and infection can cause eating, learning, and speech problems in children. Each year, oral problems are responsible for children missing almost 52 million school hours. In adults, studies have found correlations between severity of periodontal disease and risk of coronary heart disease and stroke as well as between periodontal disease and the mother’s chance of delivering a pre-term, low-birth-weight baby. And poor oral health can have a lasting impact on a person’s appearance, self-esteem, and ability to find work.
