Could a infected nerve in your tooth cause heart palpitations. I will be getting a root canal  sometime this week.

Usually not.: Although bacteria can enter your blood stream and effect your heart, this is really very rare. You do need to clear up the infection and an antibiotic may be suitable for you. Contact your dentist and tell her/him your concerns and what you are experiencing. ...Read more

It may involve the vagus nerve, which controls GI tract as well as the heart, especially the electrical properties of cardiac tissue.
