Listen Now Tooth decay affects US children more than any other chronic infectious disease. It is five times more common than asthma and almost entirely preventable. Between 41% and 55% of children age 2 to 11 suffer tooth decay and upwards of 34% of this decay is untreated. Disparities in dental health, the CDC has termed, "profound." This is explained in part by fact that one-third of the population (over 100 million Americans) lack dental health insurance. That means uninsured children are 2.5 times less likely to receive dental care than insured children. All this matters because oral health is an integral part of both overall physical (systemic) health as well as nutritional health.
