What is oral sex?

Oral sex is when someone stimulates the genitals (sex organs) of another person with their mouth. Practising safe oral sex can help prevent catching or passing on sexually transmitted infections (STIs).

How are oral sex and mouth care connected?

Oral sex and mouth care are linked because STIs can be passed on through oral sex.

STIs that can spread through oral sex include:

• chlamydia
• gonorrhoea
• herpes
• genital warts (human papillomavirus (HPV))
• human immunodeficiency virus (HIV)
• syphilis

Why is good mouth care important?

Practising good mouth care helps keep your teeth, gums and mouth healthy. It also lowers your chance of passing on or catching STIs.

Here are some mouth care tips:

• Avoid or limit sugary foods and drinks. Have them only as an occasional treat.
• Brush your teeth twice a day with fluoride toothpaste to lower the build-up of bacteria in your mouth. Gently brush your gums and tongue as well. Don't brush right before or after oral sex as brushing can cause tiny cuts in your mouth.
• If you wear dentures, clean them well. Also clean the skin under them. Rinse your mouth regularly.
• Avoid oral sex if you have sores or ulcers in your mouth or around your lips.
• Try to cut down or quit smoking as it can lead to mouth infections.
• Visit your dentist at least once a year for a check-up and clean.

Can sexually transmitted infections be prevented?

You can lower your chance of passing on STIs during oral sex by:

• using a condom or a dental dam
• getting regular STI checks
• checking your mouth and gums before oral sex — don't give oral sex if you have sores, wounds, gum disease, ulcers, cuts, herpes or an infections in your mouth
• avoiding ejaculation ('coming') in the mouth

A dental dam is a thin piece of latex placed over the vagina or anus. It forms a barrier that helps block the exchange of body fluids and lowers your chance of catching or spreading an STI.
