Had a root canal the other day and it was Painless! My first dentist said it would be some problems and that frighten me, so I went to get a second opinion and the second dentist told me there would be no problems at all, and he did the root canal within 25 minutes! He numbed the area and I didn't feel a thing! It's been a couple of days and I have had no problems. Some dentists are more experience in doing root canals. Its best to find the one that is right for you. All smiles here!
