Dental dams

Published: 07 April 2009

Dental dams are relatively thick sheets of latex squares developed by dentists to isolate a tooth for infection control purposes. Although cunnilingus and anilingus [rimming] carry a negligible to low risk of HIV transmission, dental dams have been recommended for people who wish to reduce risk further.

The following steps are recommended when using a dental dam:

  • Rinse off with water to get rid of powder coating.
  • Put some water-based lubricant on the partner’s vagina or anus and place a new latex square so that it completely covers the vaginal or anal opening.
  • Hold the dam firmly in place with both hands, and apply mouth and tongue to the unlubricated side of the dam only.
  • When done, safely dispose of the dental dam.

Many people find that dental dams are small, difficult to use and greatly reduce sensation. Dams are often available only from medical supply stores.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
