I have had several. No big deal if the dentist is good. best part is...you will never have hot or cold pain there again. I have a couple of teeth where the dentist "heroically" avoided a root canal and they have hurt ever since. Give me the root canal every time if the cavity or break is deep.

The first one I got must have been hurting for so long that I did not notice until the root canal. It was like a background noise that you heard for years that was suddenly silenced. Didn't even realize it hurt before that. Great feeling.
