Lesson Overview
About this worksheet
A tooth is easier to understand once a student can see inside it. The cross-section on page 1 shows the crown above the gum line and the root below it, with the three layers drawn one inside the next: enamel on the outside, dentin under it, and the pulp at the middle.
Section A is the labeling task with a shuffled word bank. Section B on page 2 asks which part each sentence describes, and Section C asks why a cavity stops being painless once it reaches the pulp, why the crown is the part that is armored, and what a person can do to protect enamel. Page 3 is the answer key.
The sheet fits a human-body unit and a dental-health week equally well.
How to Use This Lesson
Read the reference box and trace the three layers on the diagram.
Have students label the six numbered parts using the word bank.
Work Section B independently.
