Dentist appointments

Okay... I had great teeth. Never had a cavity until I was 7 1/2 months pregnant with Trevor. I saw this little black dot in the middle of one of my molars. I thought it was a speck of black pepper, but when I couldn't get it to go away I went to my dentist. Drat! My first cavity at the ripe old age of 23. I was fine until I was pregnant with Natalie, and then Drew. Nothing but problems since then. I don't even know how many cavities I have now. I brush and floss several times a day, but nothing seems to work. I keep getting them. I had my cleaning last week, and they found 2! *&$#! teeth! I had the upper one worked on last week, no problem. On Tuesday of this week, I had the lower one worked on... problems.
Apparently you have 2 nerves on your lower jaw. They numb both of them, and off you go. Well, not for me... of course. I have major dentist drill phobia (yes, that is the clinical term) so I hate going for anything other than a cleaning. I am a dental wimp. I would rather have surgery than have dental work done. Seriously. Well, my dentist is good, and he doesn't tease me when I'm in the chair because he knobs that I'll bolt and never return. He teases me when I see him at the gym, though. It's all good... He numbed me up, and started drilling. I had my iPod on as loud as I could to help cover up the horrible drilling sound, and then I felt it. Searing, horrible pain! He immediately stopped and gave me a couple more injections. He came back 10 minutes later and resumed working. I yelped again, and he stopped. His nurse or assistant (whatever the dental people are called) explained that most people have 2 nerves on their lower jaw. Occasionally one or both of those nerves will branch out into something like spider veins, and then you have to inject more medicine to numb up the area... not real common apparently... of course I would have this... LOL. He had to numb me deeply on the outer jaw- which, BTW, I still feel, and then in the inner jaw... that's right, next to my tongue. I still feel that too.
After all that numbing, I was good to go. He was able to finish relatively quickly. My appointment started at 3, but I didn't leave until 4:55. (I'm shaking my head.) I put on my top clear retainer (like invisaline) so when- not if- I bit myself I wouldn't draw blood. I felt like I'd been in a prize fight, and was grateful that Kent was taking care of dinner and I could get a milkshake for mine. Tooth is fixed, but I still can't open my mouth all the way, and I still have the pain. It's hard to get over the fear of dentists and their drills when this sort of thing happens, KWIM?
