Had mine out last week Friday, was out with mates in the evening and up early on Saturday for the rugby. Even had a steak roll for lunch. Not much swelling, anti inflammatories help a lot. I only ever felt pain where the one was impacted and the gum had to be cut a fair amount behind the tooth, no pain whatsoever where the others were. Did take Stilpane for 3 days though which definitely helped where the impacted one was. Reckon I have an excellent dentist (all 4 pearlers came out beautifully) and I can't believe I was so scared beforehand. Best just man up and get it over and done with. Having it done under general is a walk in the park.
Some other points:
Rinse for a minute with Corsodyl/Andolex C after every meal.
Try not to fiddle with your tongue. The weird new gaps and stitches can beg for attention but just don't.
Check that solids don't get caught in the gums below the stitches. Rinsing well should get it out. Don't eat anything too fine like foods with sesame seeds, perhaps rice, etc. Try stick to soup for the first few days. Woolies butternut soup mmm.
I miss the chewing surface area the wisdoms gave, should be fine once I can properly use my rear teeth again (still conscious about the healing gums). You will have to eat like a horse for a while.
Ice cream and frozen yoghurt etc. are great, soothing and reduces swelling.
