Any advice on how to get my dental phobic/fearful ds (9) to have a filling? Ist time was traumatic - he wasn't expecting the needle to hurt so much, and the 2nd time didn't happen; He screamed and struggled, tried to get out of the chair etc. The dentist recommended sedation at another clinic, which we tried, but it wasn't enough to calm him down and he was almost hysterical when the chair went back and the dentist approached. Has anyone tried IV sedation? I'm so worried about him losing his teeth if we can't get over this. He's very good at cleaning, mouthwash etc.
