Red and White Spots in Mouth After Oral Sex: What to Do? - Urology

Oral sex can lead to the development of red and white spots in the mouth?


I performed oral sex on my boyfriend for the first time and swallowed his semen.
After that, I immediately brushed my teeth.
A few days later, I noticed some red spots in my mouth, with some of them having white centers.
Is this dangerous? Do I need to see a doctor right away, or could it improve in a few days? I would appreciate any advice on how to help him recover, as I really prefer not to go to the doctor.

Hello: If there are red spots with white centers, rinse your mouth frequently.
If there is no improvement after 1-2 days, you should seek medical attention.
Wishing you good health.

More Info


Experiencing red and white spots in your mouth after oral sex can be concerning, especially if you are unsure about the cause and potential implications for your health. It is important to understand that oral sex, while often considered a lower-risk sexual activity compared to penetrative sex, can still pose risks for sexually transmitted infections (STIs) and other oral health issues.

The presence of red and white spots in your mouth could indicate several conditions. One possibility is oral thrush, which is a fungal infection caused by an overgrowth of Candida yeast. This condition can lead to white patches on the tongue and inner cheeks, and it may be accompanied by redness and soreness. Oral thrush is more likely to occur in individuals with weakened immune systems, but it can also develop after antibiotic use or due to other factors.

Another possibility is that the red and white spots are a result of irritation or trauma to the oral mucosa, which can occur during oral sex. The friction and pressure from oral activities can sometimes cause small abrasions or ulcers, leading to localized inflammation and discoloration. Additionally, if your partner has any infections, such as herpes or other STIs, there is a risk of transmission during oral sex, which could manifest as sores or lesions in your mouth.

Given your symptoms, it is advisable to monitor the situation closely. If the red and white spots do not improve within a couple of days, or if you experience additional symptoms such as pain, swelling, difficulty swallowing, or fever, it would be prudent to seek medical attention. A healthcare provider can perform a thorough examination and may recommend tests to determine the underlying cause of your symptoms.

In the meantime, here are some general recommendations to help alleviate discomfort and promote healing:
1. Maintain Oral Hygiene: Continue to brush your teeth gently and use mouthwash to keep your mouth clean. Avoid harsh or abrasive products that may further irritate your mouth.

2. Stay Hydrated: Drink plenty of fluids to keep your mouth moist and help flush out any irritants.

3. Avoid Irritants: Steer clear of spicy, acidic, or very hot foods that could exacerbate irritation in your mouth.

4. Use Over-the-Counter Remedies: If you are experiencing pain or discomfort, consider using over-the-counter topical anesthetics or oral gels designed for mouth sores.

5. Avoid Further Oral Sexual Activity: Until you have a better understanding of your symptoms, it may be wise to refrain from oral sex to prevent potential transmission of infections.

6. Consider Stress Management: Anxiety about your symptoms can exacerbate your discomfort. Engage in relaxation techniques or activities that help reduce stress.

While it is understandable that you may be hesitant to seek medical care, it is crucial to prioritize your health. Early intervention can help address any potential infections or conditions before they worsen. If you are concerned about confidentiality or stigma, many clinics offer anonymous testing and consultations for STIs.

In conclusion, while the presence of red and white spots in your mouth after oral sex can be alarming, it is essential to approach the situation with caution. Monitor your symptoms, maintain good oral hygiene, and do not hesitate to seek medical advice if your condition does not improve or worsens. Your health and well-being should always come first.
