Blood blister in mouth

A blood blister can develop inside a person’s mouth anywhere, not just in the area of the cheeks. Blood blisters look like small pimples. They can often appear on the gums and tongue. They are known to cause extreme pain while brushing one’s teeth when they appear on the gums.

Causes of blood blister in mouth

Oral Ulcers – When our mouth is overrun by microorganisms, it can cause open sores or wounds to form within the oral cavity. These are referred to as oral ulcers. Some medications are known to cause this skin infection as a side effect. Two main types of mouth ulcers exist: cold sores and canker sores. Canker sores, which occur inside the mouth, are the main culprit that causes mouth blisters. Canker sores in an affected individual will appear in the mouth as small oval shaped spots that look white. Quite often pus and blood can be contained within the canker sore.

Angina Bullosa Haemorrhagica – A condition that generally affects the elderly is ABH (angina bullosa haemorrhagica). Finding oral cavity blisters that are filled with blood can often be an indication of this ailment. In a majority of instances a person may develop a medium sized blister containing blood on its own. These usually appear on the underside of the tongue or the inner cheek. In much rarer cases the blister that develops in the mouth with be much larger. The blood blisters that form from ABH generally will burst after a few moments of them forming. This then causes an open wound in the area that has been affected.

Food Allergy – Another ailment that can cause a blood blister to form in the mouth is a food allergy. These will appear in the oral cavity after eating. One of the main foods that are known for causing these issues are citrus foods. The only real way to deal with this issue is to modify one’s diet, cutting out the foods that cause the blisters.

Low Platelet Count – There are tiny cells circulating in our bloodstream called platelets. These cells are what aids the blood in clotting. In cases where an individual has a very low platelet count, blood blisters can form more frequently in the oral cavity. When there is an instance of one’s platelet count dropping for no apparent reason, it is considered to be a condition called idiopathic thrombocytopenic purpura (ITP).

Injury – Damage to the tissue on the inside of the cheeks will often cause blood blisters. This can occur from consuming food that is too hot or very hard, such as toast for example.

Nutritional Deficiency – When our diets do not have the sufficient amounts of necessary vitamins, it can lead to problems developing in the oral cavity. Blood blisters that are caused due to a nutritional deficiency seem to be particularly set off by a lack of vitamin C and vitamin B12.

Prescription Drugs – Another reason for blood blisters to occur is when an individual has an allergic reaction to prescription medications. Medications that are used to treat particular diseases can often react with our body in a negative way.

Cheek Biting – Cheek biting is something we have all probably done. It happens when we get into a habit of eating food too quickly, increasing the chances of biting the inside of the cheek. Many cheek biting incidents occur when someone is talking or watching TV while eating a meal.

Oral Herpes – Herpes simplex virus type 1, also referred to as oral herpes, is another ailment where we see blood blisters forming in the inner cheeks, tongue, gums, or the roof of one’s mouth. A person will experience a sensation of burning and pain where the area has been affected. This generally occurs once a person has contracted the infection. There are other symptoms that an individual will experience with oral herpes. These would include muscle aches, fever, and fatigue. It is quite a common occurrence for repeated outbreaks of oral herpes. These symptoms can come and go regularly.

Alcohol Abuse – Blood blisters may appear in the oral cavity when too much alcohol is consumed. It is often responsible for ulcerations developing in the mouth.
