Its Sorta Like a Heli-coil?

But its for the head! The sad thing is this should not have happened. My parents and I have spent a great deal of money and I considerable time to try to keep all my teeth in my head. I am sure I paid for at least two semesters of college tuition for my old Dentist's children. 

I coughed up a crown this weekend. No big deal, but yeah it was this time. It appears there is very little left to attach a new crown to. 

  






















Options? Root canal and hope there is enough tooth to attach a new crown to. To me dicey at best and if it fails you have sunk 1K plus into the effort and THEN do this:



I'm going for the latter but this is ADA tooth number 2. Upper right rear molar. This might impede my efforts at Appleseed coming up in a month or so. 


So it appears that I am going to get my head drilled and tapped!
