Question: 1 / 1775

What would indicate an impacted tooth?

Presence of decay

Tooth that has fully erupted

Tooth that has not erupted

An impacted tooth is one that has not erupted properly and is unable to break through the gums. This condition usually occurs due to a lack of space in the jaw, abnormal angles, or other dental issues that prevent the tooth from coming in as it should. It is most common with wisdom teeth but can occur with any tooth.

In contrast, the presence of decay refers to a different dental issue, indicating that the tooth is not healthy but does not necessarily relate to whether it has erupted. A fully erupted tooth means it has emerged through the gums and is functioning typically, thus not being impacted. A removed tooth, on the other hand, is no longer present in the mouth, making it irrelevant to the concept of impaction, which specifically concerns teeth that are unable to emerge properly.
