A red blood blister in the mouth is more common than you think; it is an uncomfortable situation, looks bizarre, and causes pain. The main reason behind its formation is soft tissue trauma; however, if this issue is persistent, it may be something else, such as an infection. Let’s dig in further.

Treatment

A blood blister inside your mouth does not require external help because it either shrinks or bursts itself. If the blister was causing pain in the beginning, it might help relieve pain after popping.
