Periodontal disease tongue kiss

Hello, doctor.
I often experience bleeding when I brush my teeth, and I also bleed when biting into harder foods, like apples, or during oral suction.
I had a French kiss with someone, but I'm not sure if they also have gum bleeding.
What is the likelihood that I could have contracted HIV or other diseases? Is the risk high? How many days after exposure should I get tested?

In terms of risk levels associated with sexual behavior, no-risk activities include masturbation, hugging, and touching areas other than the genitals; low-risk activities include mutual masturbation, light kissing, mutual rubbing, and protected sexual intercourse; moderate-risk activities include deep kissing, oral sex, and withdrawal before ejaculation; and high-risk activities include unprotected intercourse and intercourse that causes wounds or bleeding.

When it comes to the transmission of infections through kissing, particularly concerning HIV and other sexually transmitted infections (STIs), it is essential to understand the risks involved. Kissing, especially deep kissing (also known as French kissing), can potentially transmit certain infections, but the risk of HIV transmission through saliva is considered very low.

In your case, you mentioned that you have a history of bleeding gums, which can increase the risk of transmission if there is contact with an infected partner's blood. However, for HIV to be transmitted, there typically needs to be a significant exchange of bodily fluids, such as blood, semen, vaginal fluids, or breast milk. Saliva contains enzymes that inhibit the virus, making it less likely to transmit HIV through kissing alone, especially if there are no open wounds or bleeding involved on both sides.

The Centers for Disease Control and Prevention (CDC) categorizes deep kissing as a moderate-risk activity for the transmission of certain infections, such as herpes or cytomegalovirus, but not typically for HIV. The risk of contracting HIV through kissing is extremely low, especially if both partners do not have visible sores or bleeding gums. If you are concerned about other STIs, such as herpes or syphilis, these can be transmitted through oral contact, particularly if there are cuts or sores present.

Regarding the timeline for testing, if you are concerned about potential exposure to HIV, the general recommendation is to get tested at least 2-4 weeks after potential exposure for initial results, with a follow-up test at 3 months for conclusive results. This is because HIV has a window period during which it may not be detectable in standard tests. For other STIs, the testing timeline can vary, so it is advisable to consult with a healthcare provider for specific recommendations based on your situation.

In summary, while there is a theoretical risk of transmission of infections through kissing, the actual risk of contracting HIV through this route is very low, especially if there are no significant wounds or bleeding involved. If you have ongoing concerns about your oral health or potential exposure to infections, it is best to consult a healthcare professional who can provide personalized advice and testing options. Regular dental check-ups and maintaining good oral hygiene can also help reduce the risk of bleeding gums and associated complications.
