A dental dam is basically a small sheet of latex which acts as a barrier between the vagina or anus and the mouth.
Dental dams get their name because they are used during dental surgery such as root canals.
Due to the possible infectious secretions from both the vagina and anus, the dental dam is becoming a more popular safer sex tool. With the introduction of different colors, shapes and sizes, manufacturers are adding some exciting changes to what once was sterile translucent-white latex.
