Down syndrome is a chromosomal disorder that occurs when a child inherits an extra copy of chromosome 21. This extra copy leads to both intellectual and physical disabilities, as well as related health problems like gingivitis. Gingivitis, also called gum disease, is a serious problem for people with Down syndrome, and severe gum disease tends to develop early for those with this condition. A particularly serious type of gum disease that affects Down syndrome children is acute necrotizing gingivitis.
