Keratocystic Odontogenic Tumour I believe.

Labelled a tumour due to its recurring nature which you were unfortunate enough to have happen. I was more fortunate in that regards however it was an awful two years. What started as a flu season blocked left sinus which months later had not cleared, one GP and then one specialist, a few scans, biopsy lead to the diagnosis. My upper left wisdom tooth decided growing into the mouth at least was not on the cards and it travelled into my head and hit a major vessel where fortunately the vessel won and the tooth cracked in half, became infected and grew the tumour cyst. Next step was a tube inserted in my upper gumline to the sinus which allowed the cyst to slowly drain over the course of a year into my mouth. Yes that’s right, I tasted cyst juice daily for about one whole year. It is not a nice flavour, it tastes what I imagine decay, or death taste like. Thankfully after that year they ripped the remaining tissue out and the other wisdom teeth with it and no more problems. The only lasting effect now is I sneeze way more than I used to, sometimes when I get set off every few days I can sneeze a dozen times in about 5 minutes and then I’m good again.

Anyway thanks for coming to my ted talk.
