Causes of Blood Blister in Mouth
Here are the several causes of blood blisters in your mouth.

Also known as aphthous ulcers, canker sores are shallow lesions that appear at the base of the gums or tissues in the mouth. These sores are not contagious but can make your talking and eating harder due to pain.
Possible causes for the development of canker sores include:
- Mouthwash or toothpastes that contain sodium lauryl sulfate
- Minor mouth injury
- Vitamin B-12, iron or folic acid deficiency
- Allergic reaction to presence of bacteria in mouth
- Emotional stress, Hormonal changes

Canker sores usually small and can disappear within two weeks. If the sore do not heal on its own and it is unusually large, see a dentist or doctor for proper treatment.
2. Food Allergies
One of the possible causes of blood blister in mouth is food allergy. Food allergies occur when the immune system thinks that a certain food or substance present in the food is harmful to your body. This triggers the immune system to release antibodies to attack the substance. This also results in itchy eyes, diarrhea, dry throat, rashes, difficulty breathing, hives, and anaphylactic shock.
The most common food allergies are triggered by protein content in fish, peanuts, eggs, nuts, wheat, milk, and sea foods. Over-the-counter antihistamines may alleviate the symptoms of allergic reaction from allergens. For severe allergies, seek medical help.
3. Angina BullosaHaemorrhagica

The blood blister heals quickly without further discomfort and scarring. However, there are cases that a large bulla does not rupture and may lead to airway obstruction.
4. Nutritional Deficiencies

Other signs of vitamin C deficiency are bleeding gums, red spots on skin, nose bleeds, digestive problems, and gingivitis.

Another possible cause of blood blister in mouth is Thrombocytopenia. Normally, a person has 150,000 to 450,000 platelets per microliter.
