Tooth Loss Associated with Cognitive Impairment and Dementia

A recent study published in the The Journal of Post-Acute and Long-Term Care Medicine (https://doi.org/10.1016/j.jamda.2021.05.009) found that tooth loss and cognitive impairment and dementia are independently associated with one another. This meta-analysis of 14 studies found that individuals with more tooth loss had 1.48 times higher risk of cognitive impairment and 1.28 times high risk of dementia. Individuals that have lost all of their teeth have a 1.40 times higher risk of dementia and 1.54 times higher risk of cognitive impairment.

Preserving the existing dentition and use of dental prosthetic was suggested to reduce the progression of cognitive decline as associated with tooth loss.
