An orthodontic bracket is made from crystalline alumina, preferably crystalline alpha-alumina. The bracket comprises a base member for attaching to a tooth and a body member extending from the base member. The body member includes walls that define an archwire groove. The walls comprise crystalline alumina. The bracket has sufficient strength to withstand normal torquing forces imparted by an archwire.
