It is possible: Our mouths are one of the portals to the rest of our body. Infections in the mouth and around the teeth can spread to the rest of the body. Of course, if you are young and healthy and have a good immune system, this isn't likely. It is the same for any other opportunity for disease to enter the body; through a cut, wound, nasal passages, etc. Just practice good hygiene to keep yourself healthy!

Affected? Maybe: Tooth infections are cited as some of the most intense pain known to people. In that regard, it could certainly affect how you operated day to day, so in a sense, yes, your brain could be affected. I would not say that your brain is at risk of being infected, however.

A 47-year-old member asked:

Can a tooth infection spread to your brain?

Yes: A very remote possibility but a possibility. This is why an abcessed tooth is a serious situation. There have been documentation that a tooth abcess was the source of a brain abcess and death. The infection can travel to other areas of the body or organs. The infection can be controlled and the tooth can be treated to eliminate the site of infection. See your dentist.

Culture the bacteria: Some common symptoms of an abscess in the brain are headache, changes in mental status, muscle or body weakness, speech slurring, nausea, fever, seizures, and or double vision. If you already have a brain abscess, the only way to determine where it came from is to culture it. There are many other causes. Only 25% of brain abscesses come from another part of the body.

May be many: Headache, changes in mentation or wakefulness, localizing neurologic abnormalities, occasionally fever may accompany brain abscess, but there are several other areas of the "brain" which may be affected. Complications are numerous. This should be cared for by a neurosurgeon and infectious diseases expert in collaboration.

The brain infection from a tooth may be a sudden, rapid, and catastrophic change in mentation and progressive deterioration in many functions, including walking, talking or other motor and cognitive skills. THis usually occurs when the possibility of brain abscess is "overlooked". Fever, "hard" neurological defects (speech, visual, etc) and headache occur in half of patients.

A 19-year-old female asked:

How would I know if I had a brain abcess from a tooth infection?

Brain abscess: If you had an imaging study for symptoms suggesting a brain abscess and it was positive and a biopsy showed oral flora in the abscess and you previously had dental issues this would be the presumptive diagnosis.
