Hi Sadie, Dentists, and specialists for the most part, do NOT tell people the truth about the RC. It is a high end money making adventure for them.
The tiny canals inside the teeth, cannot be reached by any method they use. There is always some infection remaining in the tooth. Dentists may disagree with this, saying their tools and potions get rid of all the infection. They can't as the canals are too tiny. Then you wind up with a "dead" tooth, not getting any nourishment, with an infection deep inside. These RC teeth act up eventually, then you get an expensive re-do. It is a temporary fix to a problem that continues. It is to "retain" the tooth for an indefinite amount of time, that's it.

I have one remaining RC tooth in my mouth. No it doesn't hurt, and has never acted up. However as soon as I get the $ together, I will have it removed.

I have auto immune problems already, and I don't want an infected tooth to put a strain on my immune system.

I am not even sure my own doctor as good as she is, would agree with this. However, just reading the number of posts there are about this, many people have RC's teeth that act up. I had three removed last year. I have a nesbit, which works very well. Implants are out of my price range.

These specialists, that do nothing but RC's ,make a huge profit for a small amount of their time to do this procedure.
I wish you all the best Sadie. ginnie
