The use of rubber dams in dentistry is often a topic of debate. Dental schools teach us that rubber dams are the standard of care for all restorative procedures. In the profession, they are considered the standard of care in endodontics. Instead of a dam, many restorative dentists use cotton rolls or other isolation systems. However, studies have shown that dental restorations have more predictable results as well as better durability and longevity with the use of rubber dams.
