How effective are dental dams?
Dental dams are an effective means of preventing infection from vaginal or anal secretions. To ensure the effectiveness of the barrier, check the dental dam for holes or breakage by holding it up to light or testing to see if water is able to pass through it. Be sure to rinse the dental dam before use as you or your partner may be allergic to the talc used for packaging. Do not use with oil-based lubricants, as they can break down the latex and cause leaks. Finally, only one side of the dam should come in contact with the genitals, and the dam should be used only once.
