No, not a stupid question, I didn't know that info either, but she told me since your gums are linked with arteries, there's nothing to stop an infection from spreading directly to your heart. The exact specifics she didn't specify and I'm not too sure, like if it's from blockage, muscle seizure, or what. But to clarify, just pure tooth decay isn't the culprit...it's when it gets to your gums and/or the arteries feeding your teeth and flows in your bloodstream.
