How many quadrants are in the mouth?

Explanation:
Quadrants are used in dentistry to organize the mouth for charting and planning. The mouth is divided by the midline and across the arches into four sections: upper right, upper left, lower left, and lower right. In adult dentition, each quadrant typically contains eight teeth, giving a total of 32, while in primary dentition each quadrant has five teeth, totaling 20. This four-quadrant system helps clinicians locate teeth quickly and communicate clearly about specific regions.
