I'm the root canal queen. I think every single one of my molars has had root canal. Not something I brag about, but its the truth. I have awful teeth despite brushing and flossing like a good girl.

Root canal these days is an easy procedure... if they do it the modern way with little tiny rubber tubes. Ask which method she uses. If its the rubber tubes, no biggie!

Now if money is a huge issue, like it is for me, ask for a payment plan. Motre than likely your dentist will be able ot set one up. I paid $50 a month for my last root canal.

OR if its an un-seen tooth, you can have her pull it. I also had one tooth that I had pulled when I was in college and had no dental insurance. Nobody knows its missing and every dentist since then has warned me that if I don't get a false tooth put there that my teeth will shift to fill in the spot. 15 years later and nothing moved even a millimeter.
