Well I did have a very bad experience once, the dentist actually started drilling my tooth with out giving me enough anaesthetic and when I lifted up my hand to tell him he said oh sorry then gave me some more which I swallowed. And to make things worse when he did start drilling my teeth I ended up swallowing the loose fillings I could have choked.. :gah:
I now go to a private dentist even though it cost me more but after that experience I wanted to find a dentist who was gentle and I found one and now I am not scared at all.. :D
