What do we refer to when describing the arrangement and usability of a set of teeth?

The term used to describe the arrangement and usability of a set of teeth is "dentition." Dentition specifically refers to the development and the positioning of teeth in the mouth, including their type, number, and relationship to one another. It encompasses how teeth are aligned, their function in chewing, and how they interact during oral activities. This concept is particularly important in dentistry as it affects not only aesthetics but also the efficiency of functions such as biting and chewing.

In contrast, "oral health" refers more broadly to the health of the entire mouth, including the teeth, gums, and other oral structures, rather than just the arrangement and usability of the teeth. "Tooth structure" pertains to the anatomy of individual teeth, including components like enamel, dentin, and pulp, rather than their overall arrangement in the mouth. "Dental arrangement," while it might seem similar, is less commonly used as a technical term and may not precisely convey the specific classification and systematic study associated with "dentition." Therefore, "dentition" is the most accurate and specific term for describing the arrangement and usability of a set of teeth.
