OP, if your removal person is all they are cracked up to be, seems like ya gotta be better off getting that piece a nerve poison OUT. Don't see how it could get much worse (less ya swallow some) as it's off-gassing up a storm bein fresh an all. I would get that crap out ASAP, doin precautions an the mop up like algin and big C doses(after).
If ya DO go for the tooth removal, ya need a lotta debridement afterwards so as not to have a cavitation, like I just had.
I'm sure this question will inspire a rash a information but for my 2 cents worth, don't wait, it's workin it's evil ways as tis.
Very best a luck.
And what about chucking the pest mattress?
