The tooth numbering continues by assigning teeth numbers descending to the lower left third molar (number 17) and follows the lower (mandibular) jaw up to the tooth farthest back on the bottom right side of the mouth (number 32).
The first chart is a universal numbering system adopted by the American Dental Association; the most widely used by general dentists. In lower teeth, numbering continues from the upper, begins at lower left third molar (wisdom tooth) as number 17 and ends at tooth #32, lower right third molar (wisdom tooth). See first chart above for easy understanding of the system.
