Dental Admissions Test (DAT) Practice Test

Question: 1 / 400

Which part of the tooth anchors it into the jawbone?

The crown

The enamel

The pulp

The root

The root of the tooth is the part that anchors it securely within the jawbone. It extends below the gum line and is embedded in the alveolar bone, providing structural stability and support for the tooth. The root is also surrounded by a layer of cementum, which allows it to attach firmly to the periodontal ligaments that connect the tooth to the bone. This anchoring function is crucial for maintaining the position of the tooth and for facilitating chewing and other functions.

The other options do not play a role in anchoring the tooth to the jawbone. The crown refers to the visible part of the tooth above the gum line, enamel is the hard outer surface that protects the crown, and the pulp is the innermost part of the tooth that contains nerves and blood vessels.
