From a research study:
77% of children with S-ECC had ferritin levels below normal. I think we'll get dd tested. Ds had iron deficiency when he was 2 yo and it took a year to correct with supplementation. He has perfect teeth but dd has S-ECC so presumably she is at higher risk

| The results suggest that severe Early Childhood Caries may be a risk marker for iron deficiency anemia. Since iron deficiency has permanent effects on growth and development, pediatric dentists should recommend assessment of iron levels in S-ECC patients regardless of their anthropometric appearance. |
