A dental dam is a thin, flexible barrier used to reduce the risk of transmitting sexually transmitted infections (STIs) during oral sex. It functions as a protective shield between the mouth and the genital or anal areas, preventing the exchange of bodily fluids that carry infections. This barrier method is an important tool in safer sex practices, but it is not as widely available as condoms. This guide clarifies what a dental dam is and provides an overview of where to locate and acquire one easily.
What Exactly Is a Dental Dam
A dental dam is typically a thin, square sheet of material, approximately 6 inches (150 mm) in length and width, that acts as a physical barrier. It is designed to be stretched flat over the vulva or anus during oral-to-genital or oral-to-anal contact. The material is most often latex, but non-latex versions are widely available for those with sensitivities. These alternatives are usually made from polyurethane, polyisoprene, or nitrile.
The primary function of the dental dam is to reduce the risk of STI transmission, including infections like chlamydia, gonorrhea, syphilis, herpes, and HIV. By blocking direct contact with skin and mucous membranes, the barrier prevents the passage of infectious bodily fluids. While the concept originated in dentistry, the sexual health application uses a thinner version of this barrier.
Dental dams are available in both unflavored and flavored varieties, often featuring fruit flavors such as strawberry, vanilla, or mint. Flavoring is intended to make the barrier more appealing and does not affect the material’s protective qualities.
Retail and Online Purchasing Options
Acquiring a dental dam through standard commercial channels often involves checking specific types of retailers, as availability is inconsistent compared to condoms. Traditional pharmacies and drugstores are a potential source, but stock varies significantly by location. Customers should look in the aisle dedicated to family planning or sexual health products, usually near condoms and lubricants. If they are not displayed openly, ask a pharmacist or store associate.
Major online retailers, such as Amazon, offer a convenient and discreet purchasing option with a wider selection than physical stores. Shopping online allows buyers to compare brands, materials (latex versus non-latex), and flavored options easily. Online platforms and specialized health retailers often facilitate bulk purchasing, which is cost-effective for regular users. Buyers must ensure they purchase products specifically marketed as dental dams for sexual health, not the thicker dental-grade rubber dams intended for clinical use.
Specialty stores, including adult novelty shops or sex-positive retailers, are another reliable source. These stores focus on a broader range of sexual health products and are more likely to carry a diverse inventory of options. Some medical or dental supply companies also sell these barriers, though they may require purchasing in large quantities.
Alternative Access Points
For individuals who find retail purchasing difficult or cost-prohibitive, several non-commercial access points exist. Public health clinics are a major source, frequently distributing dental dams at low cost or for free. These locations include local health department offices, STI/STD testing centers, and family planning clinics, such as Planned Parenthood. Clinic staff can also provide instructions on proper use.
University health centers and campus wellness offices often stock dental dams for their student populations. These centers make protective barriers readily available to students, sometimes alongside other free resources like condoms and lubricants.
Non-profit organizations focused on sexual health, harm reduction, and community outreach regularly include dental dams in their distribution programs. These organizations aim to remove financial and logistical barriers to safer sex supplies. Locating these organizations through local community resources provides a free alternative to standard retail purchasing.
Important Considerations When Buying and Using
Material Selection
When purchasing a dental dam, material is a primary consideration, especially regarding latex allergies. Most dams are made from natural rubber latex, which provides excellent barrier protection. Those with latex sensitivities must opt for synthetic alternatives like polyurethane or nitrile. Polyurethane dams are typically thinner, while nitrile and polyisoprene also offer reliable non-latex protection.
Storage and Expiration
Proper storage is necessary to maintain the integrity and effectiveness of the barrier. Dental dams should be kept in a cool, dry place, away from direct sunlight, heat, and sharp objects. Latex dams, in particular, are sensitive to temperature and age. Always check the expiration date printed on the packaging before use, as expired dams may be brittle or compromised, reducing their protective qualities.
Application Guidelines
For correct application, the dental dam is for single use only and must be placed over the area before any contact occurs, remaining in place until the activity is complete. Ensure the dam is not stretched and that it continuously covers the entire area to maintain an uninterrupted barrier. Never flip the dam over or reuse it, as this defeats the purpose of the barrier.
Lubricant Compatibility
Selecting the right lubricant is crucial for preventing damage to the material and ensuring comfort. Only water-based or silicone-based lubricants should be used with dental dams. Oil-based products, such as petroleum jelly, lotions, or cooking oils, can weaken or degrade the latex and non-latex materials, increasing the risk of tearing and failure.
