Abstract: A dental instrument device includes a middle body with two ends, a pair of removable instrument tips, a pair of securing collets, and a pair of removable end caps. Each end of the middle body terminates in a middle body/instrument tip connection interface that receives a right-handed instrument tip only in a first orientation and a left-handed instrument tip only in a second orientation differing from the first orientation. The removable instrument tips have a similar middle body/instrument tip connection interface, and a working instrument end with a right-handed or a left-handed orientation. A right-handed instrument tip is releasably connected to the first middle body/instrument tip connection interface, and a left-handed instrument tip is releasably connected to the second middle body/instrument tip connection interface, with the right-handed and left-handed orientations being visually distinguishable one from the other by casual observation of an ordinary observer.
