Gum bleeding most commonly occurs due to presence of deposits in your teeth which have extended below your gums. Your gums have receeded because of your faulty brushing technique mostly. Still to confirm a clinical assessment is required and rule out any other possibilities. A professional scaling is required once the lockdown is lifted.
Next Steps
In the mean time, try using warm saline mouthrinse ( salt in luke warm water) do it 3-4times a day. The bleeding will not entirely stop unless the deposits are removed. Stolin gel can be applied if gums are swollen up and bleeding is present. Other salt water is enough. Use a hexidine mouthwash to reduce the bacterial count. Twice daily 30 mins after brushing, mix with water, not to be used more than 2 weeks.
