Isolation of tooth: A rubber dam is a thin sheet of latex rubber used to isolate a tooth in the mouth. It is most commonly used to isolate a tooth when having a root canal. The purpose is to keep the area around the tooth from being exposed to saliva and bacteria. It also prevents anything from going down the throat.

Rubber Dam: Dental rubber dam is used to isolate teeth during dental procedures like root canal. It prevents saliva from entering the field and small dental endodontic files from being lost down the throat. It protects both the patient from debris and the dental field from contamination.

Protect: A thin piece of rubber to isolate a tooth from the rest of the mouth. Used a lot when you have a root canal or a bonded restoration that needs to be kept away from saliva and dry.

6x6 in thin rubber : This thin rubber sheet is used to isolat teeth from the rest of the mouth, preventing blood, saliva, and bacteria from contaminating the operative field. It also enables the dr. To see better and perform high quality work. It is mandatory for root canal procedures, and helpful in restorative procedures as well!

Tooth isolation: When treating a tooth that may get contaminated in the working environment by saliva and/or germs such as a special bonding technique or root canal, it is in the patient's best interest to isolate the tooth. A latex (or non-latex) sheet is attached by a tooth clamp and supported by a frame. A secondary advantage is that the dental dam reduces the risk of swallowing any instruments or disease tooth.
