A disposable dental mirror and methods of making same. The mirror includes a long, thin, flat blade that provides both a handle and a mirror mount and has a reflective surface applied to one end thereof. The blade is made of a material which need not be sterilizable, such as wood or plastic. In a one embodiment, the reflective surface is made of a metallized film directly applied to one surface of the blade. In an alternate embodiment, a thin, flat piece of a rigid material is located between the blade and the reflective film to ensure flatness of the reflecting surface, thereby reducing distortion.
