US scientists: each missing tooth increases the risk of dementia by 1.1%

Research has identified a potential risk factor for dementia that can be detected in the mouth.

Each missing tooth increases the risk of dementia by 1.1%. People missing all their teeth had a 40 percent higher risk of being diagnosed with dementia and a 54 percent higher risk of cognitive impairment.

The association between tooth loss and cognitive decline persisted even after controlling for confounding variables. on the results. New York University researchers suggest that oral health may be an important prevention factor.

This means that promoting good oral health and water fluoridation could reduce dementia rates on a large scale. In addition, timely fitting of dentures after tooth loss can reduce the risk.

It is more difficult to maintain good oral care in later life, when people are increasingly dependent on others for self-care. Cognitive decline can also impair hygiene, leading to tooth loss. The role of other oral diseases that may be exacerbated by tooth loss, which may increase the risk of dementia, should be explored.
