Certain types of Streptococcus bacteria, especially Streptococcus viridans, normally live in the mouth. If a tooth or gum infection is left untreated, these bacteria can enter the bloodstream and, in rare cases, reach the brain or surrounding tissues, causing severe complications.
How It Happens
Dental infection forms – Often from cavities, gum disease, or abscessed teeth.
Bacteria enter the bloodstream – Known as bacteremia, this can occur after severe infections, trauma, or dental procedures.
Spread to the brain or meninges – In rare cases, Streptococcus can cause:
Brain abscess – A localized pus-filled infection in brain tissue
Meningitis – Infection of the membranes covering the brain and spinal cord
Other complications – Sepsis or endocarditis if bacteria circulate widely
Symptoms to Watch For
Severe headache or swelling of the head
Fever, chills, or general malaise
Confusion, dizziness, or neurological changes
Persistent tooth or jaw pain
Swelling of face, eyes, or neck
Prevention and Treatment
Early dental care – Treat cavities, abscesses, and gum infections promptly
Antibiotics – Prescribed to control bacterial spread
Surgical drainage – For abscessed teeth or brain abscess if needed
Regular dental checkups – To prevent infections from starting
Final Thoughts
