Definition of dental dam

The term "dental dam" originated in the field of dentistry in the 1930s, where it was initially used as a sheet of rubber or latex material placed over a patient's teeth during dental procedures to isolate the operatory area and prevent the spread of water, saliva, and other debris. The use of dental dams in dentistry helped in maintaining a dry, sterile environment, making it easier for the dentist to work efficiently and accurately. However, the sexual health community adopted the term "dental dam" in the late 1980s, developing a new use for it as a barrier method during oral sex. In this context, a dental dam is a thin polyurethane sheet used to cover the genitals or anus during oral sex, protecting against the transmission of sexually transmitted infections (STIs), such as chlamydia, gonorrhea, and herpes. By using a dental dam, sexual health advocates aim to promote safe sex practices and reduce the risk of STIs, especially among individuals who practice oral sex. While dental dams are less commonly used than traditional condoms, they provide an additional layer of protection during oral sex, which is essential in mitigating potential health risks.
