Rubber Dam

A rubber dam is a thin, flexible sheet, typically made from latex or non-latex materials, that a dentist stretches over a frame and places around one or more teeth to isolate them from the rest of the mouth during treatment. By creating a dry, clean working field free from saliva and soft tissues, a rubber dam allows better visibility and more reliable use of adhesives and instruments, which can improve the quality and longevity of dental work.

Rubber dam use is common in procedures such as root canal treatment, composite restorations and some indirect restorations, and it also reduces the risk of swallowing or inhaling small instruments. Placement usually takes only a few minutes and is comfortable for most patients, though alternatives may be chosen if there are issues with mouth opening, severe gag reflex or specific tooth positions.
