Thanks for sharing your concern.
Gum swelling and associated bleeding could be due to gingivitis
.That is locally occurring gingival or gum inflammation
This can aggravate if neglected.
Local factor like plaque ,calculus and poor oral hygiene
leads to increased swelling and bleeding.
Its better, if you see your dentist
soon and upon evaluation, if required get your teeth cleaned once.
This is called professional cleaning or scaling.
Regular brushing cannot remove the tartar
or calculus deposited on the gum line.
Therefore, it is advised to see dentist once in six months for every individual.
