Hi,

I was recently at my regular dentist having another root c{*filter*}treament
and after about an hour and half and plenty of misery; my dentitst
informed me he could not finish the root c{*filter*}because the roots had be
come calcified??  I also another tooth, this one wit a crown already on
that they believe will  have the same problem.  

I am now in the process of waiting for my insurance company to authorize
me to see a specialist.   How is a calcified root defined??   I  am only
29, it seems that is too young for this to occur.  I have already 4
other Root Canals in the last 2 years.  Is is possible for teeth to just
fall  apart like this?/  

any assistance would be greatly apprecated.
thanks.

MM
