Have cad. #2 tooth needs root canal. no visible infection. pulpitis. does delay have systemic effects ie speed up atherosclerosis, increase mi risk?

Risk: If root canal treatment is required it usually means that the nerve of the tooth is infected. "...itis" means inflammation, again with infection usually the cause. Any infection is a danger to other organ systems. Important that you have treatment ASAP. Infection can spread readily and do damage. If you have not as yet consulted with a root canal specialist, an Endodontist, please do so.
