Explanation:
Detailed explanation-1: -The mouth is divided into four parts called quadrants. The upper part of your mouth contains the first two quadrants, and the lower portion of your mouth contains the third and fourth quadrants.
Detailed explanation-2: -Behind the canines lie the bicuspids (or premolars). The bicuspids are #4, 5, 12, 13 (upper jaw) and #20, 21, 28, 29 (lower jaw). Bicuspids are a sort of “in-between tooth, ‘’ with the properties of both the canine and molar teeth. These teeth transfer food from the canines to the molars for proper grinding.
