Dental Dams: Your Essential Guide to Safer Oral Sex and STI Prevention

We all know condoms are key to protecting ourselves from sexually transmitted infections (STIs). But when it comes to the safety of oral sex, many people aren't familiar with 'dental dams'. In reality, this is a crucial component of comprehensive sexual health. So, let's talk simply and thoroughly about how you and your partner can stay safe.

What Exactly is a Dental Dam?

Simply put, a dental dam is a thin, flexible sheet made of latex or polyurethane. It's used as a barrier during oral sex (mouth-to-vagina, mouth-to-anus) to reduce the risk of transmitting STIs.

It's vital to understand that a dental dam is not a form of birth control. It does not prevent pregnancy. Its primary purpose is to minimize the exchange of bodily fluids that can carry STIs during oral sex.

We know condoms can be used for mouth-to-penis sex. But what about protection during oral sex involving the vagina or anus? That's where dental dams come in. They are placed over the vagina or anus, acting as a barrier between the mouth and that area. This prevents the exchange of bodily fluids while still allowing for sexual stimulation.

How to Use a Dental Dam Correctly

Using a dental dam is straightforward, but careful application is key to ensure effectiveness. Follow these steps:

1. Unwrap Carefully: Gently remove the dental dam from its wrapper and unroll it. Be cautious not to tear or puncture it with fingernails or teeth.
2. Position Correctly:
   • For oral-vaginal sex, place the dam over the vaginal opening, ensuring it covers the entire area.
   • For oral-anal sex, place the dam over the anal opening, covering it completely.
   The dam should be large enough to cover the entire receptive area.
3. Hold in Place: During oral sex, use your hands to hold the dental dam firmly in place so it doesn't slip or move. You can apply a water-based or silicone-based lubricant under the dam (on the vagina or anus) to help keep it in position and enhance comfort.
4. Stop if Damaged: If the dam tears, breaks, or slips off during use, stop immediately. Discard the damaged dam and put on a new one before continuing.
5. Dispose Properly: After use, dispose of the dental dam in a trash can. Never flush it down the toilet, as it can cause blockages.

Can You Reuse a Dental Dam?

No, absolutely not. A dental dam is designed for single-use only. Reusing a dental dam significantly increases the risk of transmitting STIs to you or your partner.

Which Infections Can a Dental Dam Help Prevent?

While condoms are often the first thing that comes to mind when discussing STI prevention, oral sex can also transmit infections. Dental dams help reduce this risk for several common STIs:

• Syphilis: A bacterial infection that can cause serious complications if untreated.
• Gonorrhea: Another bacterial infection affecting genitals, throat, or rectum; sometimes asymptomatic but still transmissible.
• Chlamydia: A very common STI that often shows no symptoms but can affect the throat, rectum, and genitals.
• Hepatitis B: A viral infection affecting the liver, which can be transmitted sexually.
• HIV (Human Immunodeficiency Virus): The virus that causes AIDS, weakening the immune system.

Additionally, during oral-anal sex, dental dams provide protection against bacteria like Shigella and E. Coli found in feces.

What Infections Are NOT Prevented by Dental Dams?

While dental dams are effective at preventing the transmission of infections spread through bodily fluids, they don't offer complete protection against STIs transmitted primarily through skin-to-skin contact. This is because the dam only covers a limited area.

Examples include:

• HPV (Human Papillomavirus): A common STI; some types cause genital warts, while others can lead to cervical cancer.
• Genital Herpes: Caused by the HSV-2 virus, leading to painful sores; it has no cure and can recur.
• Pubic Lice (Crabs): Tiny insects that live in pubic hair and cause intense itching.

Making a Dental Dam from a Condom

Dental dams might not always be readily available, especially in certain areas. If you can't find one, you can improvise using a non-lubricated condom:

1. Carefully remove the condom from its wrapper and unroll it completely.
2. Using scissors, cut off the tip of the condom.
3. Cut off the rolled rim at the base of the condom.
4. Cut the condom lengthwise down one side.
5. Unroll the resulting piece – you should have a rectangular sheet that can be used as a dental dam.

Do's and Don'ts for Dental Dam Use

Do's	Don'ts
Check the expiration date before use.	Never reuse a dental dam.
Use a new dental dam for every sexual act.	Don't stretch or pull the dental dam excessively, as it can weaken.
Use only water-based or silicone-based lubricants with latex dams.	Don't use oil-based lubricants (like baby oil, Vaseline, lotion) with latex dams; they can cause the material to break down.
Dispose of used dams in a trash can.	Don't flush used dental dams down the toilet.
If you or your partner has a latex allergy, choose a polyurethane dam.	Don't use damaged, torn, or expired dental dams.

Key Takeaways

Dental dams are an essential barrier method for reducing the risk of STI transmission during oral sex. Remember they are not a form of contraception.

• Always use a new dental dam for each sexual encounter and never reuse one.
• While effective against fluid-borne STIs (like HIV, gonorrhea, syphilis), they offer limited protection against skin-to-skin transmitted infections (like HPV, herpes).
• If unavailable, a non-lubricated condom can be modified into a makeshift dam.

Practicing safe sex is vital for your health and well-being, and that of your partner. Don't hesitate to discuss any concerns about sexual health or STI prevention with your doctor.
