What is the anatomical part of a tooth where the crown joins with the root called?

The anatomical part of a tooth where the crown joins with the root is referred to as the cervix. This junction is important because it represents the transition area between the portion of the tooth that is visible above the gum line (the crown) and the portion that is embedded within the bone (the root).

While enamel, gingiva, and cementum are all related to dental anatomy, they do not describe the junction precisely. Enamel is the hard, outer layer of the crown that is responsible for protecting the tooth from wear and decay. Gingiva refers to the gum tissue surrounding the teeth, providing support and protection. Cementum, on the other hand, is a calcified tissue covering the root of the tooth, which helps anchor the tooth within the jawbone. Therefore, the correct term for the area where the crown and root meet is the cervix, highlighting the crucial role of this anatomical feature in dental health and structure.
