Tooth Number or Letter Identification

The Tooth Numbering System tables support DC047 – Tooth Number or Letter Identification.

Permanent Tooth Number System

02 = 2nd Molar (12-year molar) - Upper Right	18 = 2nd Molar (12-year molar) - Lower Left
03 = 1st Molar (6-year molar) - Upper Right	19 = 1st Molar (6-year molar) - Lower Left
04 = 2nd Bicuspid (2nd premolar) - Upper Right	20 = 2nd Bicuspid (2nd premolar) - Lower Left
05 = 1st Bicuspid (1st premolar) - Upper Right	21 = 1st Bicuspid (1st premolar) - Lower Left
06 = Cuspid (canine/eye tooth) - Upper Right	22 = Cuspid (canine/eye tooth) - Lower Left
07 = Lateral incisor - Upper Right	23 = Lateral incisor - Lower Left

B = 1st Molar - Upper Right	L = 1st Molar - Lower Left
C = Cuspid - Upper Right	M = Cuspid - Lower Left
D = Lateral Incisor - Upper Right	N = Lateral Incisor - Lower Left
E = Central Incisor - Upper Right	O = Central Incisor - Lower Left
F = Central Incisor - Upper Left	P = Central Incisor - Lower Right
G = Lateral Incisor - Upper Left	Q = Lateral Incisor - Lower Right
H = Cuspid - Upper Left	R = Cuspid - Lower Right
I = 1st Molar - Upper Left	S = 1st Molar - Lower Right
J = 2nd Molar - Upper Left	T = 2nd Molar - Lower Right
