Safer Sex
Dental Dams
What is a dental dam and why should I use one?
Dental dams are small, thin, square pieces of latex that are used for oral-vaginal or oral-anal sex. They get their name from their original purpose for use in dental procedures. Dental dams help to reduce the transmission of STIs during oral sex by acting as a barrier to vaginal and anal secretions that contain bacteria and viruses. They come in a variety of sizes and flavors.
How effective are they in preventing STIs?
How do I use them?
Dental dams are easy to use. Before using the dam you may want to rinse off any powder that's on the dam and check to make sure there are no holes or perforations. The partner performing oral sex will hold the dam against the vulva or anus of the receiving partner. You can opt to apply a lubricant on the vulva or anus before using the dam. The lubricant can help increase the sensation for the recipient. Be sure to use a water-based lubricant, because oil-based lubricants and lotions will degrade the latex and decrease the dam's effectiveness.
Some important points to keep in mind:
-
When you use the dam, be sure to ONLY use one side. If you turn the dam over and continue to use it, you will expose yourself to the very fluids you're trying to avoid.
-
Do not re-use a dam on another body part (e.g. from anus to vulva or vice-versa) because you can transfer germs from one body area to another.
-
Dams are for one-time use only.
Many people believe that using a dam will reduce the enjoyment of oral sex. The feeling of latex will be different than a tongue, but using a dental dam with lube can offer a new and pleasurable type of stimulation.
Although oral sex is considered less risky than vaginal or anal sex, there is still a risk of transmitting STIs. To be as safe as possible, use a dental dam for every act of oral sex.
How much are dental dams and where can I get them?
Dental Dams are available in the main and lower lobbies of the Health and Wellness building, at BWell On the Go stations across campus, and from SHAG peer educators and CCs in the residence halls. Brown students can also order safer sex supplies online for delivery to their campus mailbox through Ship n SHAG. All safer sex supplies are available without charge.
What if I don't have a dental dam available?
If you don't have a dental dam you can make one out a male or internal condom, latex glove, or saran wrap. To make a dental dam out of a condom, simply cut off the tip and cut down one side. To make a dental dam out of a latex glove, cut off the finger and cut down one side.
