Needs for isolation of the oral working area are rather obvious. A tooth bathed in saliva, a tongue that insists on obstructing vision and a bleeding gingiva are but a few of the obstacles that must be overcome before delicate and accurate workmanship is possible. A "Rubber Dam" is the best method to control these obstacles. It is a customized rubber sheet that feets over your teeth by a clamp and frame and we use it for most inlay/onlay, sealant, filling and root canal procedures.
