See such cases happen most frequently due to deposition of plaque and calculus on teeth which causes inflammation of gum leading to gums bleeding easily. Sometimes they are visible( supragingival) and sometimes they lie inside your gums and can't been seen directly( subgingival). If there is advanced bone loss it can be judged clinically by checking the presence of pockets which is deep spaces between the gum and tooth. Other way to judge advanced bone loss is to take an OPG,which is a full mouth x-ray. BP medicines and neuro medicines generally cause the gums to be swollen too much without presence of dirty deposits. This is called gum hyperplasia. If you do suffer from severe gum disease which is most probably due to supra or sub gingival deposits , you do need a good cleaning and flap surgeries. But get I done in good hands. Get it done in India. In the US it is gonna charge you a bomb. Do join " Dr. Runit Nangalia's Painless Dental Practice " on Facebook to get more answers about oral and general health.
