I've got a problem with my tooth. It's crowned and 3 weeks ago a pea sized lump appeared on the gum by it. Been to dentist 4 times now and despite X Ray's ( which show no infection under tooth) and 3 lots of antibiotics it is still discharging pus (sorry if tmi) on an hourly basis. Tonight I noticed the inside side of the tooth, by my tongue Is massively swollen. No pain whatsoever. The dentist wants to take the tooth out but I'm reluctant if the X-rays show nothing. Any dentists about to advise? TIA
