A bur block adapted for identifying and training dental personnel employs a block and a cover. The block has a surface having a number of holes sized to retain a number of dental burs. Each hole has indicia representing characteristics of the bur situated in the hole. The characteristics include sizes and shapes of the bur, colors, grits, part numbers, and the like. By putting the characteristics of each bur in proximity to the bur itself, persons can readily learn and/or become accustomed to the bur characteristics so that bur identification in the future is made easier.
