what are these procedures- clarification...

[Guest guest]

Okay guys, I've been reading posts and thankful for everyone's replies. But...

I was

wondering (and yes, I will read up on it, but there's nothing like first hand

experience from

people who have been through it)... what are canal wall up and down procedures?

I am

clueless on what they are exactly. Can you all help me out on explaining this

to me. my

doctor didn't exactly use these words and if he did, I may have simply been in

to much of a

haze to have heard it.

Thanks,

Pam
