Dental dam

The dental dam is the often-forgotten protective tool for oral sex practices. Yet, it significantly reduces the risk of transmitting several STIs during cunnilingus or anilingus.

The dental dam, how does it work?

An oral dam is a thin, flexible sheet, generally made of latex or latex-free polyurethane, measuring approximately 15 × 15 cm. It is placed flat over the vulva or anal area before engaging in oral sex: it forms a mechanical barrier that prevents the direct exchange of fluids while still allowing tactile sensations and warmth to pass through. Public health organizations, including the INPES, remind us that oro-genital practices remain a vector for the transmission of about ten STIs, including herpes, gonorrhea, or HPV.

In terms of use, the dam is held with both hands or applied with a water-based lubricant on the partner's side to enhance sensation. It is for single use only, in one direction, and must never be flipped over. Certain flavored versions (strawberry, blackberry, vanilla, cola) neutralize the natural scent of latex for increased olfactory comfort.

The different types of dental dams

• Flavored latex dam: the most common version, flexible and elastic, available in several scents to make the practice more pleasant on a daily basis.
• Latex-free polyurethane dam: an essential alternative in case of a latex allergy; slightly thinner, it offers excellent transmission of thermal sensations.
• Single-use dam in individual packaging: hygienic packaging that facilitates transport and guarantees the sterility of each unit before use.
• Cut-open oral condom: a DIY emergency solution; a standard condom cut lengthwise can serve as a dam while waiting to have the proper accessory on hand.

How to choose your dental dam

• Check the composition: latex for the vast majority of users, polyurethane if you or your partner have an allergy or hypersensitivity to latex.
• Choose the flavor according to your preferences: strawberry, blackberry, vanilla, or cola; the flavor masks the taste of latex and makes the practice more accessible, especially for a first time.
• Check the size and thickness: a dam that is too thick dulls sensations; prefer models described as sheer (ultra-thin) for maximum tactile transmission.
• Look at the certification: ensure that the product is approved as a class II medical device or bears the CE mark as a means of protection against STIs.
• Adapt the quantity purchased: packs of 3 to 4 units are practical for starting out; if you integrate it regularly into your intimate life, larger packages are more economical per unit.
