This is one of the first teeth to appear in a child’s mouth, typically erupting around six to ten months of age, and it is one of the most immediately recognizable tooth types in the human dental anatomy.

The specific developmental characteristics observable in the Trail Creek tooth — the stage of crown development, the degree of root formation, and various morphological features of the tooth structure — allowed dental anthropologists to estimate the age of the child at the time the tooth was formed.

Their analysis indicated that the child was approximately one to one and a half years old.
