Does Dental Hygiene Impact Brain Health?

Can brushing your teeth, wearing dentures or otherwise taking care of your teeth and gums protect memory and brain health?  One recent study suggests the answer is yes, and the impact can be significant:

“It was found that men with inadequate oral hygiene habits who did not wear dentures had a 91% greater risk of dementia than those with adequate oral hygiene habits.”

The key health behaviors are regular brushing and visits to the dentist.

While more research in needed, this is the  first study  that I have seen that suggests dental health behaviors could be important to building or maintaining or your next brain.

I am interested to hear from readers about other studies. Are there other oral hygiene techniques we should consider as tools for improving brain function or cognitive performance?
