An apparatus and method is provided for preparing a tight proximal contact between a tooth to be filled and an adjacent tooth. A tool head provides a first convex surface extending downwardly to a linear ridge. The head is divided into a pair of side-by-side fingers separated by a channel. The linear ridge defines the tip of each finger. The head is of a size to fit into a prepared cavity in a tooth. The head further provides a stepped surface, in opposition to the first convex surface, that extends downwardly to the linear ridge. Alternately, the head provides a second convex surface, in opposition to the first convex surface, that extends downwardly to the linear ridge. An elongated tool handle has a first and a second opposing bent ends. The first bent end has a 90 DEG bend, and the second bent end has a 45 DEG bend, such that the single tool may enable the formation of both distal and mesial contacts. |
