1. A method for producing a serration, comprising:
a) selecting a root-side starting contour configured as an ellipse segment and a head-side partial contour of a tooth;
b) selecting an adaptation region for at least a part of the root-side starting contour;
c) determining for the adaptation region a correction specification determined using a correction function configured as an at least third-order polynomial having at least one adjustable function parameter comprising adjustable coefficients;
d) modifying the root-side starting contour using the correction specification to form a root-side final contour, and
e) producing, by chip-removing machining, a tooth geometry comprising the head-side partial contour and the root-side final contour.
