Dental dams, also known as dental barriers or rubber dams, are thin, square sheets of latex or nitrile used in dentistry to isolate a specific tooth or a group of teeth from the rest of the mouth during dental procedures. They are vital in endodontic (root canal) treatments, restorative procedures (fillings, crowns, bridges), and other dental treatments that require a dry and clean working field. Dental dams provide numerous benefits, including improved visibility, reduced risk of contamination, protection of adjacent teeth and soft tissues, and enhanced patient comfort. Furthermore, dental dams act as a physical barrier, preventing the patient from accidentally swallowing or inhaling small dental instruments, materials, or debris during the procedure.
