"Not brushing before bed? Harvard doctor warns of 3 terrifying heart risks"
Recent research strongly suggests that skipping nighttime tooth brushing can do more than harm your smile—it may also increase your risk of heart disease.
Here's what the science says:
🦷 Oral Bacteria and Inflammation
When you skip brushing at night, bacteria in your mouth feed on leftover food particles and multiply. These bacteria can enter the bloodstream, triggering chronic inflammation, which is a known contributor to cardiovascular disease.
❤️ Heart Disease Connection
A large-scale study published in the International Journal of Environmental Research and Public Health found that individuals who skipped brushing at night had a significantly higher risk of developing cardiovascular disease. The inflammation caused by oral bacteria can affect blood vessels and the heart over time.
🧠 Expert Insights
Dr. Saurabh Sethi, a Harvard and Stanford-trained physician, emphasized that poor oral hygiene—especially neglecting nighttime brushing—can quietly endanger your heart. He highlighted three key risks:
Bacteria entering the bloodstream.
Gum disease linked to cardiovascular issues.
Better heart health among those who brush regularly.
🛌 Additional Benefits
Nighttime brushing also supports:
Better sleep quality by reinforcing a healthy bedtime routine.
Lower mortality risk in older adults, according to long-term studies.
Improved dental health in children, reducing cavities and long-term oral issues.
Bottom Line:
Brushing your teeth before bed isn't just about fresh breath—it's a simple, science-backed habit that can protect your heart and overall health. Just two minutes each night could make a big difference.
