I thought I had to have mine out a couple of weeks ago cus it was so painful & swollen(& quarter way through like yours), but got to dentist & it was a gum infection around the tooth. Had to have it syringed(which hurt like hell, think my dentist is just a bit of a bitch tho lol) & she gave me a blunt syringe to do it at home & antibiotics. Hope this is the case for you cus from what I remember its not very nice at all having it removed! Just realised I have probably shit you up even more, sorry! xx
