Abstract
A method for retaining a dental dam comprises the steps of positioning a dental dam (11) over a plurality of teeth in the mouth of a patient; selecting a section of elastomeric cord (10); elongating the section to reduce the cross-sectional area thereof; interposing a portion of the elongated section between at least two adjacent teeth and over the dam; and allowing the section to expand toward its original cross-sectional area thereby prohibiting the removal of the dam from the teeth. Also provided in combination with a dental dam (11) having a plurality of individual holes to fit over a like plurality of teeth in the mouth of a patient, is an elastomeric cord (10) having a first, relaxed diameter and a second elongated diameter of lesser dimension than the first, the second diameter being interposed between a pair of adjacent teeth and over the dam in position with respect to the teeth, wherein the first diameter forms an elastomeric wedge between the teeth to retain the dam. A novel elastomeric cord (10) is provided for retaining a dental dam which is preferably provided in a column (40 ). A method for manufacturing the column is taught as is the use of such a column in combination with a container (50).
