A dental handpiece comprising: (i) a body having a first portion and a second portion, the first and second portions (21, 25) disposed at an ergonomic angle to each other, and (ii) a drive train disposed inside the body, which comprises a drive gear extending from the second portion toward the first portion, the drive gear having a first axis of rotation, the drive gear rotatably driving at least one driven gear having a second axis of rotation, the at least one driven gear operatively connected to a dental tool disposed in the first portion to rotatably drive said dental tool about a third axis of rotation, whereby the drive gear meshes with a gear at one end of a shaft that includes a gear at the opposite end of the shaft, which gear meshes with a gear disposed at one end of a shaft including a gear at the opposite end of the shaft, wherein the shaft is configured to rotate about an axis, wherein the gear meshes with a gear at one end of a shaft that includes a collet at the opposite end of shaft for securing said dental tool, wherein shaft is configured to rotate about said third axis, so that in response to a drive source, drive gear and the shafts (26, 32, 40) are urged into rotational movement about respective axes (24, 31, 38, 46) so that dental tool mounted in collet is rotatably carried about axis, wherein said third axis is substantially perpendicular to axis, whereby in the drive train, the second axis of rotation is not coplanar with a plane containing the other axes of rotation (24, 38, 46), and the second axis of rotation is non-intersecting with respect to the first axis of rotation, and wherein the drive gear and the at least one driven gear do not include a taper gear or a face gear.
