Accelerated Dental Assisting Academy Practice Test

Dentin is the tissue that forms the bulk of the tooth and lines around the pulp. It’s produced by odontoblasts and makes up most of the tooth’s mass, providing the main structural support while surrounding the pulp chamber with a hard, tubulated mineralized matrix. Enamel covers only the crown’s exterior, cementum coats the root to anchor the tooth, and pulp is the soft tissue inside; dentin best fits the description of the tissue that forms the majority of the tooth and surrounds the pulp.
