How To Use A Dental Dam As A Barrier For Oral Sex

Dental dams are latex or polyurethane sheets used between the mouth and vagina or anus during oral sex. Ready-to-use dental dams can be purchased online.

Dental Dam Dos and Don’ts

  • DO use a new latex or polyurethane dental dam every time you have oral sex.
  • DO read the package and check the expiration date.
  • DO make sure there are no tears or defects.
  • DO put on before starting oral sex and keep it on until finished.
  • DO use water-based or silicone-based lubricant to prevent breakage.
  • DO store dental dams in a cool, dry place.
  • DON’T reuse a dental dam.
  • DON’T stretch a dental dam, as this can cause it to tear.
  • DON’T use nonoxynol-9 (a spermicide), which can cause irritation.
