A new study strengthens previous research linking dental health to dementia and cognitive decline. Researchers found tooth loss is a risk factor for cognitive decline and dementia, and with each tooth lost, the risk for cognitive impairment increases.
Older adults with more natural teeth are better able to carry out simple everyday tasks like cooking and cleaning compared to those who have lost their teeth, a new study reports. Researchers found a causal link between tooth loss and functional capacity in older adults. Tooth loss was also associated with a decline in social activity.
22% of study participants with severe gum disease developed dementia, and 23% diagnosed with mild cognitive impairment suffered extreme tooth loss. Only 14% of those with healthy gums were later diagnosed with the neurodegenerative disorder. The findings add further evidence for the link between dental hygiene and dementia.
Researchers report older adults with significant tooth loss were less physically and mentally functional than those with better oral health.
A new study shows an association between tooth loss and diminished cognitive function in adults.
