I had the one just in front of the bottom left wisdom tooth out earlier this year. I was shiiting it, but the dentist was ace. She gave me an injection, then within a minute or so said she was just going to have a feel round it, but pulled it out in one go without me even realising it.
I had always had a fear of dentists and hadn't been for years, which is why my tooth was fecked in the first place. That fear has totally gone now.
