i've had both lol.
the first time i went for the 'out' option as i'd heard so many horror stories about root canal.
dentist couldn't get all the tooth out, had smashed it all up and was strining and tugging and wrenching for ages, and then just gave up. prescribed me anti-b's so that the huge gaping jagged hole in my jaw wouldn't get an infection whilst i waited a week or so for a referral for general anaesthetic and surgery.
traumatised? the next day i drove 80 miles to a private dentist who had agreed to have another go, but could refer me within 24 hours for surgery if nec. he did manage to get it out and i spent literally a week in bed, swollen and bruised.
my root canal (lol) i had anticipated would be an easier option. my only comment would be - make sure your dentist has done some really really good x-rays, because if the root has any twists and turns, or, god forbid, right angles, in it, it's a tad trickier. like virtually impossible. mine took two hours and they had to clear the surgery because he couldn't say when / if he'd ever be finished... he was a shadow of his former self when i finally left.
what to do, what to do...
