1. In a method, for treating an interproximal carious dental lesion, the steps comprising:
providing a device comprised of a hard, rigid, generally flat shim of such thickness between opposite side surfaces as to permit its insertion longitudinally between two adjacent teeth, said shim having a top at one end and a bottom portion that terminates in a sharp and elongated edge at an opposite end, said bottom portion being formed with a bevel surface on one of said opposite sides, leading to said sharp and elongated edge, said shim having a generally longitudinal channel therein that extends from an entrance end substantially at the top of said shim to an exit end on said bevel surface for enabling delivery, from said top to said bevel surface, of a caries treating medium; inserting said shim between two adjacent teeth, with said sharp and elongated edge leading, one tooth having a carious lesion on an interproximal surface thereof; adjusting the position of said shim, as necessary, to substantially align said exit end of said longitudinal channel of said shim with the carious lesion; introducing into said entrance end of said shim channel a medium that is effective to kill or metabolically damage, directly or indirectly, carious bacteria infecting the carious lesion; delivering said medium to said exit end of said channel and thereby to the site of the carious lesion; and thereafter withdrawing said shim from between the teeth. |
