A study published in The Journal of the American Geriatrics Society says there is a relationship between dental health and dementia experienced by seniors. In 1992 They began tracking the dental habits of over 5,000 seniors with no history of dementia.
By the end of the study in 2010, 21 percent of the study group had developed dementia. Men with poor chewing function (through a lack of natural teeth) had a 91 percent higher risk of cognitive impairment, although a similar association was not found in women. However, women who didn’t brush their teeth daily had a 65 percent greater risk of dementia than women who brushed more than twice a day.
Those who exhibited the fewest signs of dementia also had at least one of the following oral health observations:
- Brushed their teeth several times per day
- Had at least 16 natural teeth or wore dentures
- Visited a dentist at least once per year
