Well done on going. are they going to put you to sleep to have it taken out?
I went years and years without going the dentist, I was in so much pain that I went in the end. I think it helps if you have a dentist that makes us feel calm, I liked my old dentist but the building got demolished and he has now retired, the one I am with now I don't like her one bit so I am going to find another dentist.
You're brave for facing this fear for the better good of your health, well done. I was exactly in the same boat. I knew my teeth had to be fixed, i could sense there was something wrong. Turned out I had about 6 holes which had to be filled, some more urgent than others. I've learnt my lesson now. I floss everyday and brush twice without fail. Prevention is always better than cure.
