Can a tooth infection cause a heart attack?

The infection and inflammation may lead to the death of cardiac tissue, which, in turn, can cause a fatal heart attack. If tooth decay is left untreated, it can not only be a pain but can also kill a person, especially those who already have pre-existing conditions or a history of heart ailments.

Is toothache related to heart attack?

Heart disease and lung cancer can also cause toothaches. In some cases, toothache may be a warning sign of a heart attack. Heart and lung disease can cause toothache pain due to the location of your vagus nerve. This nerve runs from your brain to the different organs in your body, including your heart and lungs.
