What is the worst experience at the dentist you have ever had?

I needed an extract when I was 13 or 14.I didn't know that my gum was bleeding from where he pulled my tooth out, and my mouth was completely numb from the anesthesia.The receptionist asked if I needed a follow-up appointment after I left, and I spilled blood on her desk.

Half of the patients in the waiting room ran out when the dental nurse dragged me back to the dentist to have my gum stitches.

I still have a major fear of the dentist.
