These defense mechanisms include the formation of sclerotic and tertiary dentin.

All of these wear away the tooth's enamel, allowing the dentin to show through.

The researchers used cut-in-half teeth in the study, which exposed the dentin.

The underlying dentin is softer and dissipates energy via plastic deformation.

Because of continuous deposition of dentin, the pulp becomes smaller with age.

Dentine: bone (calcified tissue) surrounding the pulp cavity of a tooth
Dentin (BE: dentine) is a calcified tissue of the body, and along with enamel, cementum, and pulp is one of the four major components of teeth. Usually, it is covered by enamel on the crown and cementum on the root and surrounds the entire pulp. ...
Inner layer of tooth structure, immediately under the surface enamel
The calcified tissue located in the middle of the tooth. It is blanketed by the enamel. It comprises the majority of a tooth's composition.
The bone-like (calcium) part of a tooth below the enamel.

This is the main tissue that forms the shape of the tooth. Dentin is the material which exists between the pulp and the enamel, and is comprised of a series of dentinal tubules stacked on top of each other.
