Another late-comer and I'm so sorry Jappy that you have to go through this. But be assured you're not going alone!!!! Would you believe this Wednesday I also have an appointment with the dentist. Had a wicked toothache in 2006, did the antibiotics and the first phase of the root canal. My dentist is a good hour's drive away so it was easy to put off going again for the final thing, so.......I did. Now some infection is back under the root canal so looks like we'll start all over again. Also have to get a couple roots "dug" out from a tooth that broke off at the gumline.
I'm the biggest chicken going when it comes to the dentist, have to take antibiotic first for mitral valve prolapse and now have to check and see if and when to stop the Coumadin so I don't "bleed out". Like somebody else mentioned, I've had many root canals and the most painful part are the shots first. With my heart "thingy", have to be sure I get the shot without epinephrine.
What time is your appointment? Mine is 2 pm -- we can pray and think of each other!! BTW, where in NJ are you? I grew up in Hackettstown.
Take care and good luck.........
