When we think about dementia care, oral health is not always the first thing that comes to mind. However, growing research suggests that looking after the mouth may play a more important role in overall brain health than many people realise.
At Protea Memory Clinic, we believe quality dementia care means caring for the whole person. That includes supporting good oral hygiene, proper nutrition, comfort, and dignity every day. While brushing teeth won’t prevent or cure dementia, maintaining good oral health is an important part of promoting overall well-being and quality of life.
The Link Between Oral Health and Brain Health
Researchers have been exploring the relationship between gum disease, inflammation and cognitive decline for several years. Recent reviews continue to show an association between poor oral health and an increased risk of dementia, although scientists are still investigating exactly how the two are connected.
One theory is that chronic gum disease causes ongoing inflammation throughout the body. Another suggests that bacteria associated with severe gum disease may enter the bloodstream and potentially affect the brain. While more research is needed, experts agree that maintaining good oral health forms part of a healthy ageing strategy.
Why Oral Care Becomes More Challenging
As dementia progresses, daily oral hygiene can become increasingly difficult.
A person may:
• Forget to brush their teeth.
• Struggle with the steps involved in brushing.
• Become sensitive or resistant to assistance.
• Experience discomfort but be unable to communicate it.
Poor oral health can lead to pain, infections, difficulty eating, poor nutrition and reduced quality of life. These issues can also contribute to increased agitation or behavioural changes.
Supporting Better Oral Health
Families can help by:
• Encouraging twice-daily brushing.
• Scheduling regular dental check-ups.
• Watching for signs of sore gums or mouth discomfort.
• Choosing foods that support both oral and overall health.
• Seeking professional assistance when oral care becomes difficult.
Small daily habits can have a meaningful impact on comfort and well-being.
