I am just wondering how long it is safe to leave an infection like

to continue trying to shift it myself (as it does
seem to be getting a little better), but don't want to risk it spreading. Also, should I consider getting a second opinion on the tooth - admittedly the tooth in question has an extremely large filling and has had to be built up at the back (don't ever get your tongue pierced, by the way, that ruined my teeth!
