Dental rubber dams are used during dental operations for different reasons. They are usually made of latex. However, there are alternatives for latex allergy sufferers. The dam is a thin sheet that is clamped in such a way that the teeth to be worked on comes through but the rest of the mouth is covered and protected. The rubber dam minimizes the splattering of blood and saliva and makes it easier for the practitioner to concentrate on particular teeth. It also prevents the patient’s gag reflex from coming on. The dam is especially helpful when fillings are introduced, as feelings need to be dry to bond properly. Its use may not be suitable for some patients, but most will be able to breathe and swallow normally with it.
