When your dentist sends you to the endodontist for a root canal or performs the procedure you may be seeing some new instruments not normally on the dental tray. One of these is the rubber dam. What exactly is it, and why is it being used?

The “dental dam”, introduced in the last half of the 18th century, is primarily used in root canal treatment, but can be used in other tooth restoration procedures as well. It consists of a thin 4” x 4” square, usually latex or nitrile (synthetic rubber) held in place on a plastic or metal frame. A small hole is punched into it for access to the tooth being treated, then the dam is spread across the patient’s mouth. The dam is held in place by a small clamp on the tooth being treated.

According to the American Association of Endodontists (AAE), there are many advantages to using a dam, the main one being to block oral bacteria from accessing the root chamber. The rubber dam provides a clean, clear surgical area for the dentist and helps prevent saliva and blood from entering into the area during treatment, similar to what surgeons do when they operate and use surgical drapes to isolate the area requiring surgery. In addition, the dam keeps the lips, beards, and mustaches out of the field of view allowing better light on the area.

Another benefit of the dam is that it often allows patients with severe gag reflexes or anxiety to undergo procedures without triggering the gag reflex or having their mouth filled with water and suction devices.

Using a dental dam is the standard of care for certain endodontic procedures in the United States, and according to the AAE, it should be required in root canals. The Centers for Disease Control and Prevention recommends the dam as a “universal precaution.” Despite the advantages the dam provides, reports from the National Institutes of Health showed that 53–63% of dentists surveyed didn’t use dams at all. Reasons included inconvenience, irrelevance (to the procedure), and patient refusal. So why bother with dams?

The AAE maintains that dental dams are effective in limiting the spread of bacteria. They also protect dentists, dental assistants, and patients from possible exposure to infectious diseases or blood-borne pathogens during procedures.

While good results for endodontic procedures are possible without a dam, using a dental dam is the more professional option.
