Which tooth anomaly is commonly associated with ectodermal dysplasia?

Ectodermal dysplasia disrupts development of structures derived from the ectoderm, including teeth. Because tooth germ formation is affected, the most characteristic dental finding is hypodontia—the congenital absence of teeth. This is why hypodontia is the best answer: patients often have fewer teeth in both primary and permanent dentitions. Hyperdontia (extra teeth) is not typical for this condition, as the issue is usually missing teeth rather than extra ones. Microdontia (smaller than normal teeth) or taurodontism (enlarged pulp chambers with certain root changes) can occur in various conditions, but they do not define the dental pattern seen with ectodermal dysplasia the way missing teeth do.
