Brief Answer:
Gum infection, Scaling, antibiotics.

Detailed Answer:
Hi..
You should get a deep scaling and curettage done in the first place...

Many times there are deposits under the gums so a deep scaling is a must...
It should be followed by a course of antibiotics like Metronidazole.
You should also massage the gums with gum paint...
Do antiseptic mouthwash(Hexidine) gargles.
Do warm saline gargles...

Get scaling done every 6 months.

Brush your teeth twice a day, once in morning and once before sleeping at night.
Also, learn a proper brushing technique from your Dentist...

Hope this helps. Let me know if I can assist you further.
