I completly understand.  My husband and our boys -
 Simon & his brother Zero just wen through the 
same thing when Zero broke off one of his 
enormous upper canines.  He fell off a balcony 
and the tooth pierced his bottom lip and broke 
off.  They said the extracton of the tooth would 
be very traumatic and take 6 months + to heal.  
So we searched for a cat dental specialist and he 
got it capped instead.  I didn't know you could 
cap a cat's tooth.  I would have had it done in 
gold but it would have been $500 extra.
Anyway we've got or fingers & paws crossed for 
you!!!
