Quite by chance following the recent discussion about going to the dentist I had to have a tooth extracted this morning. NO PROBLEMS!!!!!!!!!!!
I reminded my dentist about the non adrenaline injection and he laughed. He said in his opinion the injections (which were not painless) cause as much natural adrenaline as the normal injection would so he felt it was all a bit of a non event really although he complied with my wishes. INR up to 2.5 is quite acceptable to him and all he did was to apply a pressure pad for a minute or two and give me a few extra so I didn't look like Dracula after a feast on the way home. 1/2 hour later and face is coming back to life and bleeding stopped.
OK so I know we are all different and some people have higher pain thresholds etc but trust me when I say I am a devout coward about dentists and this was a breeze. I would still rather have an ablation mind than go through it too often.
