Having dificulty finding dr. to perform root canal on infected molar. what is the urgency of getting fixed, w/cardiac background? pain is unbearable.

Root canal: If your cardiologist gives you medical clearance, it should not be hard finding someone to do the needed root canal. They should at least get you on some type of antibiotic therapy.

Urgent: It is urgent that you have your tooth treated. You want to see an endodontist, specialist is rooot canals. Thwy are experienced in treating patients like you with a cardiac problem. Depending on your condition, they may need to consult with your cardiologist. Most endodontist offices have time in their schedules for emergencies so they will schedule quickly and start treatmentasap. Call today.

Immediate: Jc, go immediately. Any infection can spread, and you would want your tooth to be addressed as soon as possible. Call your dentist to get a referral to an endodontist as soon as possible.

Endodontist: Have your dentist immediately refer you to an endodontist. They are specialists trained to treat difficult root canal procedures.

I can't see why: There should be no reason for what you describe. I'm not sure what your 'cardiac background' refers to. I suggest that you speak to your cardiologist and have him\her prepare a written medical clearance to go ahead with the rct along with any precautions necessary prior to and during treatment. With that in hand, any qualified endodontist can start treatment asap (unless it jeopardizes your life).
