well,it happened to me the other week ,when i had a tooth extracted ,the new crown i had only just replaced,(second time in fact)

he took big chunk out of the crown leaving the crown in half
by rights ,the dentist should replace it ,for free ,but i have so many problems with dentists at moment ,i cannot afford to make a fuss ,until i getr my other teeth sorted out ,then i may say about whats he going to do about the crown he has broke
obviously your oral surgeon rang you at home (which they dont normally do)
as he is concerned what he has done,i would if i was you ,dotn shout or anythign ,just calmly say ," is he prepared to pay for new crown to be put on the tooth he broke" see what he says ?
hopefully if he is a decent dentist he will put one on free of charge
as i cant see your own dentist doing it for free ,as he never broke it
good luck
