Rubber dam (dental dam)

Also called: dental dam, dam sheet, isolation dam

A stretchy sheet with holes punched for the teeth, which isolates them from saliva.

The rubber dam is a sheet of latex or non-latex material. Holes are punched for the teeth to be treated, and the sheet is stretched over them and held with a clamp and frame. It keeps the area dry, keeps small instruments and irrigants out of the throat, and holds back the cheek and tongue.

How to spot it

  • A square sheet (often green, blue or gray) that comes in different thicknesses.

What it is used for

  • Root canals, many fillings and bonding procedures.

Safety and care

  • Ask about latex allergy; use a non-latex dam when needed.
  • Dam sheets are single-use.
