The isolation technique helps protect the teeth for all types of dental procedures including root canals, bleaching, and restoration preparation and delivery. It is held in place by a clamp that surrounds the tooth and a framework that keeps the rubber approximated to the mouth and cheeks. Another name for this device is a rubber dam. 

A dental dam is a medical device which is used by dentists to maintain a sterile work area when they are drilling and filling teeth. Safer sex advocates have also adopted the dental dam, because when used correctly during oral sex, it can prevent the transmission of sexually transmitted infections (STDs).

The dental dam is a piece of thin, stretchable latex or non latex material that becomes a barrier to selected teeth when applied. A dental dam is a protective cover that is placed over a tooth being worked on.
