Gum bacteria implicated in Alzheimer's and other diseases
Researchers are reporting new findings on how bacteria involved in gum disease can travel throughout the body, exuding toxins connected with Alzheimer's disease, rheumatoid arthritis and aspiration pneumonia. They detected evidence of the bacteria in brain samples from people with Alzheimer's and used mice to show that the bacterium can find its way from the mouth to the brain. (2019-04-07)

New technique could help regrow tissue lost to periodontal disease
According to the US Centers for Disease Control and Prevention, about half of all Americans will have periodontal disease at some point in their lives. Characterized by inflamed gums and bone loss around teeth, the condition can cause bad breath, toothache, tender gums and, in severe cases, tooth loss. Now, in ACS Nano, researchers report development of a membrane that helps periodontal tissue regenerate when implanted into the gums of rats. (2019-03-21)

New membrane class shown to regenerate tissue and bone, viable solution for periodontitis
Periodontitis affects nearly half of Americans ages 30 and older, and in its advanced stages, it could lead to early tooth loss or worse.

Periodontitis may raise the risk for developing dementia
Gum disease (gingivitis) that goes untreated can become periodontitis, causing loss in the bone that supports your teeth. Periodontitis is the main cause of tooth loss in adults. Periodontitis is also a risk factor for developing dementia. Recently, researchers in South Korea studied the connection between chronic periodontitis and dementia. They published their findings in the Journal of the American Geriatrics Society. (2019-03-15)
