Which term is used for a tooth that has not yet erupted into the oral cavity?

• A. Erupted
• B. Retained
• C. Unerupted
• D. Impacted

Answer: (C)

Describing eruption status uses terms that tell where a tooth is in the eruption process. When a tooth has not yet broken through into the mouth, the correct term is unerupted. It simply means the tooth is still within the jawbone or soft tissue and hasn’t emerged into the oral cavity yet. That’s exactly what the question describes. Erupted means the tooth has already emerged into the mouth. Impacted describes a tooth that cannot erupt because something blocks it—bone, another tooth, or abnormal position. Retained is used when a tooth has erupted but remains in the mouth or remains in the eruption path longer than normal (often referring to deciduous teeth that haven’t exfoliated or a tooth that has already erupted but isn’t shedding as expected). So unerupted is the precise term for a tooth that has not yet erupted.
