Oral Health Issues After Oral Sex: What You Need to Know - Otolaryngology

Oral issues


Hello doctor, two months ago I had a sexual encounter with a sex worker and performed oral sex.
Since then, my throat has been uncomfortable and itchy.
I haven't noticed any lesions in my mouth, but I'm very worried that I might have a sexually transmitted infection (STI).
I'm currently abroad and it's not convenient for me to seek medical help.
I had a blood test done, which showed no gonorrhea, hepatitis, HIV, or chlamydia.
However, I understand that blood tests cannot detect genital warts, right? My mouth has been uncomfortable for two months now, and I'm not sure what to do.

Dr. Zheng Jueyi reply Otolaryngology


Hello, if you are currently asymptomatic and there are no obvious lesions in the oral cavity, you may start with self-observation.
Additionally, throat itching and discomfort may be related to gastroesophageal reflux; it is advisable to manage your diet and increase water intake.
If the symptoms persist without improvement, it is recommended to seek medical evaluation.
Wishing you safety and health.
Sincerely, Dr.
Jue-Yi Cheng, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

Engaging in oral sex can carry certain health risks, particularly concerning sexually transmitted infections (STIs). Your concerns about throat discomfort and the possibility of having contracted an STI after oral sex are valid and warrant careful consideration.

Firstly, it’s important to understand that oral sex can transmit various STIs, including gonorrhea, chlamydia, syphilis, herpes, and human papillomavirus (HPV). While you mentioned that you have tested negative for gonorrhea, hepatitis, HIV, and chlamydia, it’s crucial to note that not all STIs are detectable through standard blood tests. For instance, HPV, which can lead to oral warts or even oropharyngeal cancer, may not show up in blood tests. Additionally, some infections may take time to manifest symptoms or be detectable, so if you have ongoing symptoms, further evaluation may be necessary.

Your throat discomfort and itchiness could be indicative of several conditions. One possibility is pharyngitis, which can be caused by viral infections or bacterial infections, including those transmitted through oral sex. If the discomfort persists, it would be wise to consult an ear, nose, and throat (ENT) specialist who can perform a thorough examination and possibly recommend a throat swab to check for infections that may not be detected through blood tests.

Moreover, while you may not have visible lesions in your mouth, some STIs can still cause symptoms without obvious signs. For example, oral herpes can sometimes present with mild symptoms or be asymptomatic. If you suspect that you might have been exposed to herpes, it may be beneficial to discuss this with your healthcare provider, as they can recommend specific tests for herpes simplex virus (HSV).

In terms of managing your symptoms, maintaining good oral hygiene is essential. Rinse your mouth with warm salt water to soothe throat irritation, and consider using over-the-counter pain relievers or throat lozenges to alleviate discomfort. Staying hydrated and avoiding irritants such as tobacco or alcohol can also help.

If your symptoms persist beyond a few weeks or worsen, it is crucial to seek medical attention. Persistent throat discomfort could be a sign of a more serious condition, and early intervention is key to effective treatment. Additionally, if you are in a location where access to healthcare is limited, consider reaching out to telehealth services that can provide guidance and possibly prescribe medications if necessary.

Lastly, regarding your concerns about the potential for HPV and its association with oral health issues, it’s worth noting that while HPV is common and often clears on its own, certain strains can lead to more serious health issues, including cancers. Regular check-ups and discussions with your healthcare provider about vaccinations (like the HPV vaccine) and screenings are important for maintaining your health.

In summary, while your initial tests are reassuring, ongoing symptoms warrant further investigation. Seek specialized care if your throat discomfort continues, and maintain open communication with healthcare professionals about your sexual health and any concerns you may have. Remember, proactive health management is key to ensuring your well-being.
