Answer:
It actually depends on the person, the better you care for it, the faster the swelling will go down.
In some cases it can take up to a week.
Just make sure you wash it with antibacterial soap 3 times a day and make sure that you keep your fingers off of it.
Ice help to reduce swelling too.
I have spider bites and a monroe so I'm used to this type of thing
:]
also you should use biotene mouthwash,
and salt soaks, you put 1/8-1/4 of salt in a 8 once glass of water swish it around in you mouth dont swallow any though.
if you put to little in the glass it wont have an effect, (if i does it will be very slightly) if you put to much it will cause irritation :/
i have spiderbites and i did this and it helped alot! :) i hope it works out for ya!
