Untreated tooth decay could be silently damaging your heart.
It’s now scientifically clear: cavities can be deadly — not just for your teeth, but for your heart.
A large-scale meta-analysis found that people with severe tooth loss face a 66% higher risk of dying from cardiovascular causes compared to those with little or no tooth loss. This isn’t just about chewing or smiling — it’s about life expectancy.
Why does this happen? When dental infections go untreated, harmful oral bacteria can enter the bloodstream. This can lead to chronic inflammation, which plays a major role in the development of heart disease.
In fact, according to Dr. Andrew Waxler, a cardiologist at Penn State Health, individuals with untreated tooth infections are 2.7 times more likely to develop cardiovascular issues like coronary artery disease.
Maintaining good oral health isn’t optional — it’s directly connected to heart health and overall longevity. Prevent cavities. Treat infections early. The mouth is not separate from the body — it’s the gateway to it.
