Reuters Health reports on a new study that finds children who develop cavities and gum disease may be more likely to develop risk factors for heart attacks and strokes decades later than kids who have good oral health. Kids who had even one sign of poor oral health were 87% more likely to develop subclinical atherosclerosis; children with four signs of poor oral health were 95% more likely to develop this type of artery damage. Periodontal disease in adults has long been linked to increased risk of cardiovascular disease.
