Your dental story and experiences mirror mine almost exactly! I'm very hard to numb so all my dental work as a girl was done basically without any numbing, including root canals! Now, I'm paranoid of dentists. Luckily I've found a wonderful, patient dentist who takes the time to explain everything and make sure I'm totally numb before he touches my teeth. Recently I needed to have three teeth in three different areas removed, so I had the oral surgeon put me under totally as it was more than I could take. I'm missing a lot of teeth also, and as soon as I recover from Tuesday's surgery, I begin the process for partials. Getting older sure is rough.....but beats the alternative I guess. You have three weeks until your surgery-I'm guessing you should be healed enough by then.
