Thanks for asking the query ,
Bleeding from the gums is mainly due toinjury , infection and inflammation of the gums.
It occurs due to plague

Systemic conditions like GERD
, vitamin deficiences , bleeding disorders , leukemia
changes can lead to bleeding gums .
and get complete check up done .
Take an OPG .
Get complete mouth scaling and polishing done .
Take vitamin suplements .
Develop a habit of brushing tooth twice daily with a soft bristle toothbrush .
Develop a habit of using dental floss and interdental cleaners .
Oral cancers occurs if you have a long term habit of using tobooco,smoking
, you dont have a cancer so dont worry at all .
