Is it possible to transmit infections through deep kissing when there are sores on the tongue?


If a person has wounds in their mouth or on their tongue and engages in kissing, deep kissing, or French kissing with a sex worker who is HIV positive, there is a potential risk of transmission.
The likelihood of HIV transmission through oral contact is generally considered to be low, but it is not zero, especially if there are open sores or bleeding gums involved.
In such a situation, it is advisable to consult a healthcare professional as soon as possible.
They can assess the risk and determine whether post-exposure prophylaxis (PEP) is necessary.
PEP is most effective when started within 72 hours after potential exposure to HIV.

The likelihood of HIV transmission through saliva is not very high; however, if there are open wounds, it is still advisable to seek medical evaluation.

More Info


Deep kissing, especially when there are oral wounds involved, raises valid concerns regarding the transmission of HIV. To address your question, it is important to understand the mechanisms of HIV transmission and the specific circumstances you described.

HIV (Human Immunodeficiency Virus) is primarily transmitted through specific bodily fluids, including blood, semen, vaginal fluids, rectal fluids, and breast milk. The virus requires direct access to the bloodstream or mucous membranes to establish an infection. In the context of deep kissing, the risk of HIV transmission is generally considered low, but certain factors can increase that risk.

1. Presence of Oral Wounds: If you have an open sore or wound in your mouth, this could potentially increase the risk of HIV transmission if the other person is HIV-positive. The risk is particularly heightened if there is blood present from either party. If your wound is healing and not actively bleeding, the risk remains low, but it is not zero.

2. Blood Exposure: The most significant risk factor in your scenario would be if there was blood-to-blood contact. If the person you kissed had bleeding gums or an oral wound that bled during the kiss, and that blood came into contact with your open sore, there is a potential risk for transmission.

3. Saliva: Saliva itself is not a significant vector for HIV transmission. The virus is present in saliva, but in much lower concentrations compared to blood or other bodily fluids. Therefore, casual contact through saliva, such as kissing without the presence of blood, poses a very low risk.

4. Other STIs: While HIV is a concern, other sexually transmitted infections (STIs) can also be transmitted through oral contact, especially if there are wounds or sores. It is essential to consider the full spectrum of STIs and their transmission routes.

5. Post-Exposure Prophylaxis (PEP): If you are concerned about potential exposure to HIV, it is advisable to consult a healthcare provider as soon as possible. PEP is a treatment that can reduce the risk of HIV infection if started within 72 hours after potential exposure. Your healthcare provider can assess your risk based on the specifics of your encounter and determine if PEP is appropriate for you.

6. Testing: Regardless of the immediate risk, it is a good practice to get tested for HIV and other STIs if you have concerns about potential exposure. Testing can provide peace of mind and help you manage your sexual health proactively.

In summary, while the risk of transmitting HIV through deep kissing is generally low, the presence of oral wounds and potential blood exposure can increase that risk. It is crucial to consult with a healthcare professional who can provide personalized advice based on your specific situation and may recommend PEP if deemed necessary. Regular testing and open communication with partners about sexual health are essential components of maintaining overall health and safety.

A gentle kiss is unlikely to cause infection, but if there is vigorous sucking, it can lead to mucosal damage and result in infection. The same applies to kissing; avoiding vigorous sucking or breaking the skin will prevent transmission.
