ABSTRACT:
A method and means facilitating the application of etching agents to a tooth surface for bonding, laminating or the like dental processes. A manually manipulable matrix of a relatively flexible absorbent material dimensioned to correspond to a tooth surface to be treated is provided. This matrix is impregnated with any suitable etchant. A carrier handle is provided which may be formed integrally with or secured to the matrix. In use, positioning of the etchant impregnated matrix adjacent to the surface to be bonded insures the desired application of etchant to the tooth area to be etched.
