Over on WWAS, CJC talked about getting dental implants 3 years ago.  IIRC, she had them done on both sides of her mouth.  Well, this morning, I had my first one, had to have been in one of the hardest places to work, too.  Last tooth,
upper left side.  Hardest part was the actual drilling, because I had to hold my mouth open wide sideways as well as up and down, and my jaw doesn't go that far (since wisdom tooth surgery 51 years ago). 
Funny that she uses a torque wrench to screw the post into the bone, I thought she could have just gone down to the local Home Depot and bought one, but this is a specialized wrench.  I felt it click when she reached the right torque, but it was just funny to see her working the wrench in front of my face. Oh well.
Two-and-a-half hours in the chair.  Not much pain, but apparently, plenty of blood.  She was very conscientious about the amount of anesthetic, since I have a resistance to them, they have to give me more, and usually more than one time. 
I go back in a week for a check-up, and probably weekly after that for a month or so, and then the impression will be sometime in 4 months or so, and then the crown will probably be a month after that. So, maybe by Christmas, I'll have a new tooth.
Makes me wish that we could work on regenerative therapy where we could grow a new tooth to replace the old one, or a new heart, liver, etc.   I guess it'd be fine, except for the brain - for some people, that's beyond replacing -
