<s>[INST] Hi, well this is hard to explain, my gum is a little swollen and it hurts, only in one spot though, in the very back, and i noticed that between my tooth and the gum there was something stuck there, as soon as i take it out it was something white that didn t have a normal smell, i don t know if it could be rests of food or what, i need help, also i would like to know, i ve been very paranoid because some of my tooth feel just a little bit loose, should i be worried? [/INST] Helloit seem your gums have got highly inflamed called gingivitis. This occurs because of food accumulation in between gum sand teeth because of improper cleaning under the action of bacteria gums get inflamed leading to swelling tooth loosening bleeding foul smell. White hard material may be calculus, it is a calcified structure stuck on tooth in case of bad oral hygiene.I would advise you to go for deep cleaning of your teeth called scaling, use Betadine mouth rinse twice daily and learn the proper brushing technique.
