Just as in case of a blood blister on the breast, it is natural and in fact necessary to be concerned when a blood blister appears in the mouth. It can be a source of discomfort, a symptom of an underlying health condition and a potential cause of infection.

This vacuum gets filled with blister fluid and blood leaking from damaged blood vessels. A tight and red bubble-like bump results in the end.
In most cases, blood blisters in the mouth will disappear even without treatment. They mostly appear on the inside of the cheeks, on the roof of the mouth and sometimes on the gums.
