Scientists have shown a link between tooth loss and dementia


  • Each year, there are approximately 10 million new cases of dementia worldwide.
  • Most adults have 32 teeth. Among these teeth, there are 8 incisors, 4 canines, 8 premolars and 12 molars (including 4 wisdom teeth).

A new study shows that there is a proven link between tooth loss and dementia. To reach these conclusions, British researchers compiled the results of 14 trials including more than 34,000 adults. Within this group, more than 4,500 people had impaired cognitive function.

Conclusion: Compared with those who had all of their teeth, people who lost at least one tooth were 1.48 times more likely to have impaired cognitive function, and 1.28 times more likely to develop a form of dementia.

The number of missing teeth is important

In addition, the risk of neurodegeneration was associated with the number of missing teeth. Thus, with each additional tooth dropped, the probability increased by 1.4% for a decline in cognitive function. The risk of developing dementia increased by 1.1%.

“Our results underscore the importance of maintaining good oral hygiene in order to maintain cognitive function,” The authors concluded.
