Solution

The correct option is B

0,1,2,22,1,2,2


In each set, incisors (I) are indicated first, canines (C) second, premolars (P) third, and finally molars (M), giving I, C, P, M.

The dental formula for both upper and lower jaws together is written in the form of a fraction: I,C,P,MI,C,P,M

The dental formula for an adolescent human is 2,1,2,2 for upper teeth indicating 2 incisors, 1 canine, 2 premolars, and 2 molars on one side of the upper mouth. After losing the two upper incisors, Nirav's dental formula will be 0,1,2,22,1,2,2
