ASPEN Dental Assisting Practice Exam

The nerve of the tooth inside the root below the dentin is called

Pulp Pulp Chamber Dentin Nerve

Correct Answer:

Pulp

Explanation:

The soft tissue inside the tooth that contains blood vessels and nerves is the dental pulp. In the root, this tissue fills the root canal and is known as the radicular pulp. The phrase “inside the root below the dentin” points to this pulp tissue, not the hard dentin that surrounds it. The pulp chamber refers to the crown portion of the pulp, while dentin is the hard tissue forming the tooth walls. The term nerve isn’t used by itself to name the tissue; nerves are part of the pulp’s contents. So, the tissue inside the root beneath the dentin is the pulp.
