Dental infections are more than just toothaches. In rare but serious cases, Streptococcus bacteria from an untreated tooth infection can travel through the bloodstream and affect the brain. Understanding the risks and acting quickly can save your health — and even your life.
What Is a Streptococcus Dental Infection?
Streptococcus dental infections often start as cavities, gum disease, or abscessed teeth. Streptococcus viridans, a common oral bacterium, can cause pus formation, swelling, and severe tooth pain. If left untreated, the infection can enter the bloodstream (bacteremia) and spread to other organs, including the brain.
How a Tooth Infection Can Spread to the Brain
Dental infection forms – Tooth decay or gum infection creates a bacterial hotspot.
Bacteria enter the bloodstream – This is called bacteremia and can happen even after dental trauma.
Spread to the brain or meninges – Rarely, Streptococcus bacteria can cause:
Brain abscess (pus-filled pocket in brain tissue)
Meningitis (infection of brain and spinal cord membranes)
Other complications – Sepsis or heart infections (endocarditis) may also occur if bacteria circulate widely.
Symptoms to Watch For
If a dental infection spreads, you may notice:
Severe headache or facial swelling
Fever, chills, or fatigue
Confusion, dizziness, or neurological changes
Persistent toothache or jaw pain
Swelling around eyes, face, or neck
If you experience these symptoms, seek immediate medical attention.
