In modern day dentistry, patient care has evolved beyond just drilling and filling. With improvements in materials, techniques, and infection control standards, one piece of equipment remains surprisingly underutilised — the rubber dam. Yet its importance cannot be overstated.
What is a rubber dam?
A dental rubber dam is a thin, flexible sheet—usually made of latex or a latex-free alternative—that your dentist uses to isolate the tooth or teeth being worked on. A small clamp is used to secure it in place, and the dam is then stretched over a frame to create a clean, dry workspace. While it might look and feel a bit odd at first, it is an essential tool for predictably delivering high-quality, long-lasting dental care.
Why isolation matters
Many dental procedures such as fillings, root canal treatments, or other restorative procedures, often use materials that are extremely sensitive to moisture. Saliva, blood, or even the water spray from dental instruments can contaminate these materials. If this happens, it can compromise the bond between the filling and the tooth.
Contamination leads to:
- Weakening of the bond between the filling and the tooth
- Increased risk of sensitivity after the procedure
- Higher chances of the filling failing or deteriorating faster
By keeping the tooth dry and free of contaminants, the rubber dam ensures the best possible environment for treatment success.
Benefits beyond moisture control
Beyond just keeping things dry, the rubber dam also:
- Helps you stay more comfortable, by reducing water exposure and need for frequent rinsing or interruptions during treatment
- Improves visibility for the dentist, leading to more precise and efficient work
- Protects your airway, minimizing the risk of swallowing or inhaling dental materials, disinfectants, and instruments
- Enhances infection control, keeping your mouth shielded from materials and disinfectants used during the procedure
There are even certain dental procedures such as root canal treatments where a rubber dam is not optional but seen as the standard of care. Without it, there’s a serious risk of bacterial contamination, and the procedure’s success rate can drop significantly.
Why don’t all dentists use a rubber dam?
In many cases, it comes down to habit, convenience, or outdated training. Some dentists find the process of placing a rubber dam time-consuming or believe patients find it uncomfortable. However, modern techniques and materials make placement fast and easy — and most patients are surprised at how much more comfortable it can make their visit.
Bottom line: it’s about standards
If your dentist doesn’t use a rubber dam when it’s clinically appropriate, it’s worth asking why. And if the answer doesn’t involve a valid clinical reason, it might be time to consider a provider who prioritizes best practices and long-term outcomes over shortcuts.
At our clinic, we use rubber dam whenever isolation is needed — because your treatment deserves the best chance of success. And frankly, you do too.
