floater
n.— «Verts doesn’t consider himself a doctor, anyway. He’s a horse floater, one who “floats,” or files down, teeth. Some say floaters got their name from their partiality to drifting about the country. Others think they were named for the similarity of their hardware to the flat-faced tools—floats—used for finishing concrete.» —“Horse dentist floats around in a stable job” by Ellen Barlett in Davie, Florida Washington Post Dec. 1, 1982.
