Understanding Dental Dams: History And Development
A dental dam is a thin, six-inch square sheet of latex used during dental procedures or oral sexual activities to prevent the transmission of diseases.


What is a Dental Dam?
 It acts as a protective barrier by covering the dental work area or genitals during oral contact. The dam forms a physical barrier that blocks the transmission of fluids from the mouth to the dental work area or genitals and vice versa.

History and Development
The Dental Dam was invented in the late 19th century and originally used during dental procedures to isolate the operating field and protect the patient's mouth. It helped prevent debris, fluids, and microorganisms from potentially contaminating other areas of the mouth during procedures like root canals or cavity treatments. Over time, the dam's uses expanded to also include protecting against disease transmission during oral sexual activities.

In the 1980s, the AIDS epidemic fueled more widespread recognition of the dam's potential to prevent sexually transmitted infections. Public health campaigns increasingly promoted dental dams and other barriers as effective methods to reduce STI risks during oral sex. While dams are still mainly associated with sexual healthcare today, their initial purpose was protecting patients during dental work. The invention of this simple yet ingenious barrier has aided infection control in both healthcare and sex for over a century.

How Dental Dams Prevent Disease Transmission

Dental dams form an impermeable barrier that blocks the exchange of bodily fluids between mouths and genitals. This physical separation helps interrupt the transmission pathways of diseases that can pass from one person to another through contact with infected fluids. Some key ways dental dams prevent transmission include:

- Blocking viruses, bacteria, and other microbes from passing between saliva/pre-ejaculate and genital secretions during oral contact. Many STIs are transmitted through contact with or exchange of these bodily fluids.

- Trapping potentially infected fluids released from the genitals or mouth under the dam, keeping them isolated from the other person's body. Fluids cannot cross the dam's impermeable latex surface to gain entry into the other person.

- Absorbing or containing microorganisms to reduce their ambient concentrations and chance of transmission. Pathogens trapped under the dam are less able to infect the other person compared to freely circulating in fluids.

- Acting as a reminder barrier that interrupts behaviors conducive to disease transmission, like prolonged direct fluid contact during oral sex without protections. Dams promote safer sex practices.

Usage and Benefits of Dental Dams During Oral Sex

To use a dental dam during oral sex, simply unwrap the latex square and place it over the vulva or anus prior to performing cunnilingus or anilingus. Hold it taut with your hands or secure it with clothespins or clips. The dam creates a clean, protected barrier field to enjoy oral contact through without the risks of fluid exchange and potential infection.

Benefits of dams for oral sex include:

- Reduced transmission risk of STIs like gonorrhea, chlamydia, herpes, HPV, and HIV that can spread through contact with genital fluids and secretions.

- Protection for people with open cuts or sores in their mouth which could facilitate disease entry and spread if directly exposed to a partner's body.

- Safer alternative to unprotected oral sex that maintain spontaneity while establishing vital disease barriers for fluid contact activities.

- Usable with fluids-based lubricants for a smoother experience compared to "dry" barriers that can more easily tear or lose integrity.

While dams may seem unarousing, taking time to discuss safer sex practices with partners can increase intimacy and caring for one another's sexual health. Dam use should always be a consensual choice.

Recommendations to Improve Dental Dam Access and Use

Despite proven effectiveness, dental dams are still underutilized for disease prevention during oral sex. Public health experts recommend several strategies to increase acceptability and access:

- Educate people that dams do not diminish pleasure but rather allow safer enjoyment of fluid contact activities. Focus messaging on health benefits over restrictions.

- Make dams available in different flavors, colors and materials beyond just latex for those with allergies. Variety could appeal to more users.

- Provide free dams at clinics, schools, events and online to remove cost barriers that discourage experimenting with the method.

- Train healthcare providers to recommend dams as casually as other safer sex methods so discussions help normalize use.

- Highlight how dams can be incorporated into foreplay and different sex positions versus just protection. Present as an enhancement rather than hindrance.

Increased open conversations, education, availability and encouragement of dams could go far in curbing the spread of STIs impacted by oral sex behaviors. Their simple yet profound role in protecting sexual health deserves more acknowledgement and promotion.
