Recent scientific research has revealed a compelling connection between oral hygiene practices, particularly brushing teeth at night, and the risk of cardiovascular disease. Toothbrushing and cardiovascular disease are often related! As holistic dentists, we at Sydney Holistic Dental Centre have long advocated for the integral role of oral health in overall wellbeing.
One of the simplest yet most effective habits you can adopt is brushing your teeth twice daily. This routine keeps your smile bright and plays a crucial role in preventing cavities, gum disease, and bad breath. Moreover, maintaining good oral hygiene is linked to better overall health, reducing the risk of conditions such as heart disease and diabetes.
This article explores the authoritative background evidence supporting the importance of nightly toothbrushing in reducing cardiovascular disease risk.
At SHDC, we strongly recommend the good-health principle of twice-daily toothbrushing as a habit to contribute to long-term wellbeing.
- Oral-Systemic Health Connection: Poor oral hygiene, (especially neglecting to brush teeth at night), may increase the risk of cardiovascular events due to systemic inflammation.
- Periodontal Disease: Inadequate oral care can lead to periodontal disease, a significant risk factor for cardiovascular disease.
- Nightly Toothbrushing: A study from Osaka University Hospital shows that brushing teeth at night is crucial for reducing cardiovascular disease risk.
- Holistic Approach: For optimal oral and cardiovascular health, nightly brushing, proper technique, flossing, and regular dental check-ups are essential.

Understanding the Oral-Systemic Health Connection
The relationship between oral health and cardiovascular disease is complex and multifaceted. Poor oral hygiene may increase the risk of cardiovascular events. This connection is rooted in the systemic inflammation that can arise from periodontal disease and poor oral health.
Periodontal Disease: A Significant Risk Factor for Heart Health
Periodontal disease, often resulting from inadequate oral care, has been identified as a risk factor for cardiovascular disease and heightens cardiovascular disease risk. The bacteria and inflammatory mediators associated with periodontal disease can enter the bloodstream, potentially affecting the heart and blood vessels. This underscores why maintaining good oral hygiene, particularly brushing teeth at night, is crucial for cardiovascular health.
The Impact of Toothbrushing on Cardiovascular Disease Risk
A groundbreaking study conducted at Osaka University Hospital has provided compelling evidence for the importance of nightly toothbrushing:
- Participants who reported brushing their teeth at night had significantly higher survival rates compared to those who did not brush at all.
- The estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk was markedly lower for those who brushed three or more times daily (7.3%) compared to those brushing 0-1 times daily (13.7%).
These findings suggest brushing teeth at night is important for lowering cardiovascular disease risk. Remember, at SHDC, we strongly advocate twice-daily toothbrushing!
The Perils of Poor Oral Hygiene on Cardiovascular Health
Neglecting oral care, especially at night, can lead to a cascade of health issues:
- Bacterial Proliferation: Skipping nightly brushing allows bacteria to multiply, leading to plaque formation and heightening cardiovascular disease risk.
- Periodontal Disease Development: Consistent poor oral hygiene can result in periodontal disease, a known risk factor for cardiovascular issues.
- Systemic Inflammation: The inflammatory response triggered by poor oral health can contribute to atherosclerosis and other cardiovascular problems, thus heightening cardiovascular disease risk.
- Increased Risk of Heart Disease: Studies have shown a correlation between poor oral health and an increased risk of heart disease, including heart failure.

The Holistic Approach to Oral and Cardiovascular Health
At Sydney Holistic Dental Centre, we emphasise the importance of a comprehensive approach to oral care:
- Twice-Daily Brushing: Brushing teeth in the morning and at night before bed is crucial for removing the accumulation of bacteria and food particles.
- Proper Brushing Technique: Brush for at least two minutes using quality toothpaste and a soft-bristled brush.
- Flossing: Incorporate daily flossing to remove plaque and food particles between teeth.
- Regular Dental Check-ups: Professional cleanings and examinations are essential for optimal oral health.
- Holistic Health Considerations, including the importance of brushing at night to lower the cardiovascular disease risk: In our dental care approach, we consider factors such as diet, lifestyle, and overall health.

The Importance of Toothbrushing Timing
Research indicates that the timing of toothbrushing is significant:
- Brushing teeth at night may be more effective in reducing cardiovascular disease risk than brushing only in the morning.
- A study in Nature Journal found that those who brushed their teeth at night but not upon waking had better cardiovascular outcomes than those who only brushed in the morning.
Beyond Cardiovascular Health: The Broader Impact of Oral Care
While our focus has been on cardiovascular health, good oral hygiene practices have far-reaching effects.
- Perioperative Oral Care: Proper oral care can reduce postoperative complications for patients undergoing heart valve surgery.
- General Health: Good oral health is linked to better overall health outcomes, potentially reducing the risk of various systemic diseases.
- Dental Health: Regular brushing, especially at night, helps prevent dental caries and maintains the integrity of tooth enamel.
Conclusion: A Call to Action for Better Oral and Cardiovascular Health
The evidence is clear: brushing teeth at night is critical to maintaining good oral health and reducing the risk of cardiovascular disease. As holistic dental professionals, we urge our patients to recognise the importance of this simple yet powerful habit.
By incorporating nightly toothbrushing into your routine, you’re not just caring for your teeth – you’re taking a significant step towards better heart health and overall wellbeing, preventing gum disease and lowering cardiovascular disease risk.

Frequently Asked Questions About Nightly Toothbrushing and Cardiovascular Health
Q1: How does brushing your teeth at night reduce the risk of cardiovascular disease?
A: Nightly toothbrushing helps remove bacteria and plaque accumulated throughout the day. This reduces the risk of periodontal disease linked to systemic inflammation. Maintaining good oral hygiene may decrease the risk of cardiovascular disease and improve overall health.
Q2: Is brushing teeth after waking as effective as brushing at night for cardiovascular health?
A: While brushing teeth after waking is important, research suggests that brushing at night may be more crucial for reducing cardiovascular disease risk. Participants who brushed their teeth at night had better cardiovascular outcomes than those who only brushed in the morning.
Q3: How often should I brush my teeth to maintain good oral and heart health?
A: For optimal oral and cardiovascular health, brush your teeth at least twice daily—once in the morning after waking and once at night before bed. Some studies suggest that brushing three or more times daily may further reduce your risk of cardiovascular disease.
Q4: Can poor oral hygiene increase the risk of heart failure?
A: Yes, studies have shown a correlation between poor oral health and an increased risk of heart failure. Maintaining good oral hygiene, including regular toothbrushing, may help reduce the risk of hospitalisation for heart failure.
Q5: Is there a link between missing teeth and cardiovascular disease?
A: Some research suggests a correlation between tooth loss and increased cardiovascular disease risk. This association might be due to shared risk factors or the systemic effects of periodontal disease. Maintaining good oral health and preserving natural teeth may improve heart health.
Q7: Is brushing your teeth before breakfast necessary for cardiovascular health?
A: While the timing of morning brushing is less crucial than nightly brushing for cardiovascular health, brushing before breakfast can be beneficial. It removes overnight bacterial buildup and protects your teeth from acid erosion during eating.
Q8: How does alcohol consumption at night affect oral and cardiovascular health?
A: Consuming alcohol at night can negatively impact both oral and cardiovascular health. It can lead to dry mouth, increasing the risk of tooth decay, and may interfere with good oral hygiene practices. Additionally, excessive alcohol consumption is a known risk factor for cardiovascular disease.
Q9: Can improving oral health help patients with existing heart conditions?
A: Yes. Maintaining good oral health is particularly important for patients with existing heart conditions. Proper oral care can reduce complications in patients undergoing heart valve surgery. Always inform your dentist about any heart conditions you have.
Q10: How does periodontal disease increase the risk of cardiovascular disease?
A: Periodontal disease can increase the risk of cardiovascular disease through systemic inflammation. The bacteria and inflammatory mediators from gum disease can enter the bloodstream, potentially affecting the heart and blood vessels and contributing to cardiovascular problems.
Remember, while good oral hygiene is crucial for cardiovascular health, it’s just one part of a holistic wellbeing approach. A balanced diet, regular exercise, and routine check-ups with your dentist and doctor are all important for maintaining good overall health.

A related Australian Study…
A cross-sectional study conducted in Sydney, Australia, examined the oral health status, behaviours, and knowledge of patients with cardiovascular disease (CVD). While this study did not specifically focus on toothbrushing frequency and cardiovascular outcomes, it provided some relevant insights:
- The study surveyed 318 patients with CVD from cardiac rehabilitation and outpatient clinics in Sydney.
- Key findings included:
- 81.1% of participants reported having at least one oral health problem.
- 41.2% had not seen a dentist in the preceding 12 months.
- Only 10.7% had received any oral healthcare information in the cardiac setting.
- Patients with valvular conditions were more likely to have received oral health information compared to those with other cardiovascular conditions (40.6% vs 7.4%, p < 0.001).
- Only half of the participants had adequate oral health knowledge.
- The study concluded that despite a high incidence of reported oral health problems, many patients lacked knowledge about oral health, were not receiving oral health information from cardiac care providers, and had difficulty accessing dental services.
