Lovely to put faces to names at Dr Sanjay Gupta's talk in York yesterday. Was encouraged to hear that local without adrenaline/epinephrine does work from people. Being me had to dig a bit. My dentist said cautiously "It's a less intense anaesthetic" which did not fill me with confidence. i am an utter wimp and as I am having two big fillings replaced at the same time ( no escape they are old and crumbling (like me) I would like to hear positive experiences. Also found a bit of research that said as long as it was less than 0.04mg should be OK.
