The Health Smiles Healthy Growth 2018-19 Report found that the oral health of Illinois children is slowly improving, but tooth decay is still a significant issue affecting two in five Illinois children. Approximately 22 percent of third-grade students have untreated tooth decay, down from 30 percent in the previous decade. While more children now have dental insurance, there are still significant disparities in the oral health status of certain population groups.

Good oral health care is important for children. Poor oral health can lead to pain, missed school days, distracted learning, difficulty eating, poor nutrition, loss of social confidence, and in severe cases, even death. Healthy baby teeth also help properly guide adult teeth into alignment.
