When the upper layer of skin is wounded, a blister forms, which is a fluid-filled sac. The fluid comes from the wounded tissue and is usually clear. A blood blister in the mouth forms when the fluid pools and acts as a barrier, shielding the wounded skin from further harm. Blood veins beneath the wounded skin may rupture, allowing blood to fill the blister’s “bubble,” resulting in a Blood Blister In Mouth. Most blood blisters occur where there are friction, just as clear blood blisters.

If you’ve ever had the unfortunate experience of biting your cheek while chewing food, you may recall a sore developing in the area. While mouth sores from cheek biting are normally not a cause for concern, what if you find a bloody sore in your mouth?

Angina Bullosa Hemorrhagica/ Oral Blood Blister In Mouth

ABH can also be caused by anaesthetic dental injections and steroid inhalers. In half of the instances, no reason can be found.
