Hello, my name is Hind, I had some serious problems with my upper teeth (front 8, from premolar to premolar) the only solution to make them look nice was to get crowns on all 8 since I had bad teeth 6 out of 8 where post crowns, plus... I had a crown lengthing surgey.

Moving on, ever since I had them placed I haven't visited the dentist which I regret now, since between my central teeth I'm starting to get a gap (problem 1) and my gums have been flammed ever since, very itchy and painful when I bite hard food (problem 2) and my last problem that I'm facing is that I'm starting to feel and see that line that separates the crown from the actual tooth/root.

I have no idea what to do I know I should visit a dentistbut before I go to my dentist I would like to have a clue to what the hell is going on :S

Go to the dentist. He or she will be the only person who can tell you why these things have been happening to your teeth. Or else, please visit me and open your mouth so I can see your teeth in person and then take you to MY dentist.
