Yes, you can get a UTI from oral sex in some cases. Saliva can carry bacteria from the mouth to the urethra, which may increase the risk of a urinary tract infection (UTI).
UTIs usually happen when bacteria from the skin or intestines enter the urethra. However, some bacteria linked to UTIs can also be found naturally in the mouth.
Sexual activity, including oral sex, can make it easier for bacteria to reach the urinary tract. The risk may be higher with spermicides, poor hygiene, or having multiple sexual partners.
If you have UTI symptoms, it is important to see a healthcare provider, as most UTIs need to be treated with antibiotics.
