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 the anus, the dental dam is becoming a more popular safer sex tool. With the introduction of different colours, shapes and sizes, manufacturers are adding some exciting changes to what once was sterile translucent-white latex. Dental dams are an extremely effective means of preventing infection from vaginal or anal secretions. Be sure the dam is free of holes or breakage. You can check the dam before you use it by holding it up to light or seeing if water is able to pass through it.
