Good day everyone,
I just wanted to thank everyone for your opinions and advice. To give you a little recap of what I decided on, I went ahead without GA to see if it would go smoothly, and I let the Doctor know that at any point in time if S5 needed to be restrained in any way, the procedure needed to stop.
Got to the doctor's office, S5 was calm no anxiety at all. They had him pick out a movie so he could watch it on the overhead TV. The dental assistant administered the (very potent) cocktail of liquid drugs, and S5 was in Lala land. After he was given Oral anesthetics, he fidgeted but was so drugged up that he went straight back to watching spiderman. Te Doctor informed us that he was going to do the procedure in two steps, we waited for the oral numbing to do it's job and the the Doctor numbed again. Because this was a very large tooth with very long roots, the Doctor needed to "wiggle" it out and at this point S5 was still very drugged up. He squirmed a little bit while the tooth was being extracted but we did not need to restrain him. I have to say that the worst part of all this procedure was getting my son home. What a total relief, and S5 has absolutely no recollection of being at the Doctor's office!
And as for his father, well when he got to the office, he was under the impression that S5 was being put under GA, thus even after I had explained that we would try with the simpler awake procedure. Now in the room he questioned on how long S5 would be sleeping (goof)...After the extraction, I asked the clerk to divide the bill into two, I paid my part and he paid his, crisis averted and end of a crappy, emotional, nerve racking procedure.
So again, thank you for all the support in regards to my questions. Have a splendid day!
