Hello, I having shortness of breath for the past 3 weeks, first time in my life experiencing this consistently, It almost never happened...I have a tooth that is going bad and causing some pain...My heart and lungs were checked by Xray at the E.R...How could I find out if it is my tooth, should I just have it pulled, would my Dentist be able to help with the diagnoses or should I try to get them to connect...thanks for your help
