A new study shows that skipping tooth brushing at night can put more than your smile at risk it may also harm your heart. Researchers found that poor nighttime oral hygiene is linked to a higher risk of cardiovascular disease due to bacteria that thrive in the mouth while we sleep.
When teeth aren’t brushed before bed, bacteria multiply and trigger gum inflammation. This allows toxins to enter the bloodstream, contributing to artery plaque, higher blood pressure, and greater chances of heart problems. Nighttime is especially critical since saliva flow drops, making it easier for bacteria to grow unchecked.
Experts recommend brushing for at least two minutes with fluoride toothpaste, along with flossing and mouthwash. This simple habit doesn’t just protect against cavities it also supports long-term heart health, proving that caring for your smile can also protect your life.
