Is any of this happening?
Be seen today
Seek same-day medical or urgent dental care if:
Bleeding continues after 10 minutes of uninterrupted firm pressure
Bleeding is heavy, repeatedly fills your mouth, or follows dental treatment
You also have unexplained bruising, frequent nosebleeds, or blood in urine or stool
You have fever, facial swelling, pus, or feel significantly unwell
You take a blood-thinning medicine and the bleeding will not stop
Arrange care sooner for loose teeth, receding gums, persistent swelling, pain, or bad breath.

Does any of this apply?
Book an appointment
Book a dental appointment if bleeding keeps returning or lasts longer than about two weeks despite gentle daily cleaning.
A medical appointment may also be appropriate if you bleed from several parts of the body, recently started a medicine, or have a condition affecting clotting.
Every sign above is quoted from the sofidex article on Bleeding gums. If you are not sure, err upward — it is always reasonable to be checked.
