A removable dental mandrel guard, the mandrel shaft defining a longitudinal axis, the guard comprising: a collar portion extending from a first open end to a transition region along a longitudinal axis parallel mandrel shaft axis, the collar including a first portion comprising a hollow cylindrical interior cross-section with first interior diameter not greater than the diameter of the dental tool to which it is intended to attach and a second interior diameter proximate the transition region, the transition region reducing from the second interior to a third interior diameter; a shaft guard extending from a first end rigidly connected to the transition region to a second end rigidly connected to the disc shield along a longitudinal axis parallel with the mandrel shaft axis, the shaft guard having a hollow cylindrical interior cross section extending greater than 180 degrees in circumference defining the third interior diameter; a disc shield comprising opposed first and second transverse walls, each of the first and second transverse walls having a partially enclosed perimeter edge joined by coextensive edge wall extending from a first edge point to a second edge point, the second transverse wall extending transversely from the first edge point to the second edge point, the interiors of the first and second transverse walls and edge wall defining a disc cavity; and, a continuous open seam extending longitudinally from the collar portion first open end to the shaft guard second end, the seam merging with the disc cavity.
