You have Gingivitis
which is an inflammation of the gums. Bleeding from the gums is the first sign of it. You should get a scaling of your teeth done once in 6 months and follow proper oral hygiene
instructions. A periodontal flap surgery would be required if periodontitis
has occurred. Flossing of your teeth should be done once a day to improve the health of your gums. A chlorhexidine
mouth wash could be used twice daily for 3 weeks and the instruction to use should be followed properly.
