A gear (60) for use in a gear pump (2) having intermeshing gear teeth (62) includes indentations (64) formed on one or both of first and second sides of at least one of the multiple gear teeth of the gear. Each of the indentations is of sufficient size to allow material to flow into the indentation during counter-rotation of the intermeshing gears (60u, 60l). Material processed by the gear pump and otherwise trapped between the intermeshing gears flows into the indentation, which forms a channel that connects to the outlet chamber. The otherwise trapped material flows into the outlet chamber. The gear having gear tooth indentations decreases the amount of material trapped between the intermeshing gears and thereby decreases the amount of material squeezed out the sides of the gears and improves material flow within the gear pump.
