molar (2)

[L. molaris, grinding]
A grinding or back tooth, one of three on each side of each jaw. The first permanent molar erupts between 6 and 7 years; the second between the 13th and 16th years. The third molars (wisdom teeth) are extremely variable, usually erupting between the 18th and 25th years; however, they may erupt later or not at all.
