Using a rubber dam for dental procedures can provide multiple advantages. A rubber dam can provide a clean and dry operating field away from substances such as saliva and blood. This is important for dental procedures as the bonding ability of adhesives and cements is heightened in a clean and dry field away from possible contamination, in order for maximum adhesive strength between the restorative materials, dentin and enamel. If the environment is contaminated leading to poor bonding of the materials, the success and longevity of the restoration is shortened.

When using the rubber dam, it is possible to isolate one or more teeth. By doing this, the clinicians visibility of the tooth is greatly improved, due to the increase in contrast with the rubber dam around the tooth or teeth, whilst at the same time it retracts the soft tissues such as the lips, tongue, and cheeks, and reduces mirror fogging:allowing the clinician to focus solely on the restorative site, which can lead to the procedure also being more time$efficient. Even though it is commonly said that the rubber dam takes too much time to apply, in many ways it can reduce the time needed for the procedure, as not only does it isolate the tooth, it reduces the ability for the patient to communicate with the clinician. This is most beneficial for the over talkative patients which can sometimes hinder the efficiency of treatment and can instead allow more time for the clinician to focus on the task at hand in order for the procedure to take less time.تجهیزات دندانپزشکی
