Research indicates that elderly people are less likely to get dementia if they have more teeth.
According to a Journal of the American Geriatrics Society report, the risk of Alzheimer’s within a space of five years rose 62% for people with ten to nineteen teeth, in comparison to those who still have 20 or more in their smile. Meanwhile, people with one to nine are %81 more at risk.
Dentures provided by a dentist may play a part in levitating the risk, however, as the report indicates that people without a single tooth are at %63. The dentist community suggest that this phenomenon may be connected to dietary changes, or perhaps to the boost which chewing gives to the flow of oxygen and blood to the brain.
– Research shows that, amongst elderly people, those with fewer teeth are generally at a greater risk of dementia.
– The exception to this is people without a single tooth, who are at a comparatively low risk of dementia, possibly due to using dentures to restore their smile.
– Potential reasons for this include dietary change brought on by tooth loss, or how the act of chewing boosts oxygen and blood to the brain.
Dr Ohara and colleagues followed 1,566 Japanese men and women aged over 60 between 2007 and 2012, during which time 180 or 11.5 per cent developed dementia, mostly Alzheimer’s.
