I went through the exact same thing, was told by my dentist that I would get novacaine only to extract my tooth, my dental insurance did not cover for complete anethesia. I couldn't believe it but I didn't feel a thing either but I sure was scared. I am still very afraid of dentist and don't go as often as I should, my bad.

I know I spelled a couple of words wrong but couldn't find the 'speller check'.
