When we think about oral health, we usually associate it with our teeth and gums. However,  research is increasingly revealing a surprising and complex connection between oral health and neurodegenerative conditions. Neurodegenerative diseases, such as Alzheimer's and Parkinson's, are characterized by the gradual loss of nerve cells and cognitive functions. In this blog, we explore the link between oral health and neurodegenerative conditions, highlighting how taking care of our oral well-being may play a role in supporting brain health and our risk of developing neurodegenerative conditions.

Periodontal Disease and Cognitive Decline

Periodontal disease, a severe form of gum disease, has been linked to cognitive decline and an increased risk of developing Alzheimer's disease. Chronic inflammation caused by the bacteria associated with periodontal disease may release inflammatory markers into the bloodstream, which can potentially impact the brain and contribute to cognitive impairment.

Oral Bacteria and Neurotoxic Proteins

Certain strains of oral bacteria, especially those associated with periodontal disease, can produce neurotoxic proteins. These proteins have been found in the brains of individuals with neurodegenerative conditions, leading researchers to investigate a potential connection between oral bacteria and the development of these diseases.

Aspiration Pneumonia and Cognitive Impairment

In elderly individuals with cognitive impairment, swallowing difficulties may lead to aspiration pneumonia, a lung infection caused by the inhalation of food or liquid. Poor oral health and untreated dental problems can increase the risk of aspiration pneumonia, further impacting cognitive functions in susceptible individuals.

Promoting Oral and Brain Health for a Sharper Mind

• Maintain Excellent Oral Hygiene: Brush your teeth at least twice a day and floss daily to reduce the risk of gum disease and related inflammation.

• Regular Dental Check-ups: Schedule routine dental visits for early detection and timely treatment of oral health issues.

• Promote Healthy Eating: Consume a balanced diet rich in antioxidants, omega-3 fatty acids, and vitamins beneficial for brain health and oral well-being.

• Stay Mentally Active: Engage in activities that stimulate your mind, such as puzzles, reading, or learning new skills.

• Manage Systemic Health Conditions: Keep chronic health conditions, such as diabetes and hypertension, under control to promote both oral and brain health.

• Stay Hydrated: Drink plenty of water to maintain saliva production and oral health.

The connection between oral health and neurodegenerative conditions is an ever-evolving area of research that underscores the importance of holistic healthcare. By prioritising regular dental care, adopting a brain-healthy lifestyle, and staying vigilant about our oral hygiene, we take another step towards supporting both our smiles and our minds.

This wraps up our week-long Mind Body Mouth journey through the often under-acknowledged links between oral health and general health.  We hope that you’ve had many takeaways and have a new found appreciation for the value of prioritising your oral health as part of a wholistic approach to well-being.
