Question: 1 / 1775

What is hyperdontia?

Teeth that are underdeveloped

Teeth that appear in addition to the regular number of teeth

Hyperdontia refers to a condition in which an individual has an excessive number of teeth beyond the normal count. Typically, adults have 32 teeth, and children have 20 primary teeth. When someone has hyperdontia, they may develop additional teeth known as supernumerary teeth. This condition can lead to overcrowding, misalignment, or other dental issues due to the presence of these extra teeth.

While options that mention underdeveloped teeth, abnormal shapes, or alignment relate to dental conditions, they do not accurately define hyperdontia. Understanding this condition is essential for recognizing its implications in dental health and treatment planning.
