Granted that going to the dentist regularly is not a particularly fun activity to look forward to. Now, researchers have found another reason why such regular visits are needed; it could help reduce the risk of developing dementia, according to DailyMail.

Gum disease and dementia
A team of researchers from Finland undertook an observational study to investigate previous works that have linked poor oral health to dementia. This is based on the theory that the same bacteria that cause gums to bleed can reach the brain, with the potential to adversely impact it.
For their study, they looked at data from 47 previous studies on periodontitis – a severe form of gum disease that can cause a loss of jaw bone, gaps under the teeth and severe damage to the tissues that support your teeth. They sought to establish a connection between cognitive decline or dementia and oral health, according to the research published in the Journal of the American Geriatrics Society.
After reviewing existing literature linking periodontitis to dementia, the Finnish researchers found that people with this dental problem and missing teeth had a 23% risk of developing cognitive decline or dementia.
From a clinical perspective, our findings emphasise the importance of monitoring and management of periodontal health in the context of dementia prevention.
Limitations
Although they found enough evidence to corroborate previous studies on the subject, the team said the quality of proof found was weak. They recommend further research into the relationship between gum disease and dementia risk.
Available evidence is not yet sufficient to point out clear ways for early identification of at-risk individuals, and the most efficient measures to prevent cognitive deterioration.
It is estimated that more than 900,000 people in the UK have one form of dementia or the other. This figure is projected to increase to 1.6 million by 2040, according to the Alzheimer’s Society.
