STOP what ever on earth your doing that has rotted all the teethe of a 2 year old.
To have 7 root canals on baby teeth of a 2 year old would either kill th kid or destroy their health now/future, etc..
I suggest you stop your life and rethink what you have done and figure out a plan of action to correct these problems.
I have heard so many horror stories coming out of Canada and thir social medicine or what ever they call it up there and it scares me, sound like it is 10x worse than the USA. In the USA we have allot of choices that you guys apparently don't have.
Make a list of all the bad things that have caused this and a plan of action to correct this, thats what I suggest you do first!
