Can Gum Disease Spread to the Brain?

August 30, 2025

Many patients wonder, “Can gum disease spread to the brain?” While gum disease starts in the mouth, research shows it can have serious effects on overall health, including the brain.


Gum disease, or periodontal disease, is caused by bacteria that build up on the teeth and gums. If left untreated, these bacteria can enter the bloodstream and travel to other parts of the body. Studies suggest a possible link between advanced gum disease and conditions such as Alzheimer’s disease, dementia, and even stroke. The inflammation caused by gum bacteria may contribute to brain inflammation, which can impact cognitive function over time.


It’s important to note that not everyone with gum disease will develop brain-related health problems, but the risk is higher when gum disease goes untreated. The good news is that gum disease is preventable and treatable. Brushing twice daily, flossing, and scheduling regular dental cleanings greatly reduce the chances of bacteria spreading beyond the mouth.
