A good reason to go to the dentist regularly is to protect against gum disease because studies have shown the bacteria from gum disease can move into the blood stream and trigger other problems, even heart trouble.
Now, it's blamed for something more.... dementia.
Scientists reporting in the Journal of Alzheimer's Disease now believe gum disease can get into the brain too and leave an impact there.
Researchers in the UKfound signs of bacteria linked to gingivitis in four out of 10 samples of brain tissue from Alzheimer's patients. But in people who had never shown signs of dementia, they could find no sign of gingivitis in any of those brain samples.
