Maintenance of good occlusion and chewing ability is critical to maintaining memory, strength, balance, and brain function. This is important at all ages, but particularly for the elderly. Elder care services need to be including bite assessment. Research has shown that one’s ability to chew hard foods has a strong influence on memory, brain inflammation, and the ability to recover from head trauma and strokes. The jaw nerve (trigeminal nerve) controls blood supply to the brain, hence has a major effect on brain function, neurodegenerative diseases, cognition, and memory.
