Hi Talkcraft
I have had a pretty awful time with dentists over the past three years. Its not in your head if you react to the injection, and it could be for a variety of reasons. I react worse to the shots with adrenaline or whatever, but I react to the ones without as well, just not as strongely. Like you, it is a marked response and quite unmistakeable. I personally would not go back to that dentist as they sound money hungry and arrogant. I would also never let anyone give me a another root filling or put anymore metal in my mouth.
