Blood Blister in Mouth: 8 Causes and 12 Remedies

A blood blister in the mouth is a fluid-filled bump that appears on the mucous membrane of the oral cavity. It can occur on any part of the mouth, including the inside of the lips, the tongue, and the cheek. A blood blister is typically caused by damage or trauma to the blood vessels beneath the skin’s surface. However, in some cause, it may indicate an underlying issue. This article will discuss what causes a blood blister in the mouth and the 12 best natural remedies to treat it at home.

8 Common Causes of Blood Blister in Mouth

1. Accidental Biting or Chewing

One of the most common causes of blood blisters in the mouth is accidental biting or chewing of the oral tissues.

We’ve all experienced moments where we unintentionally bite the inside of our cheek or lip while eating or talking.

Such incidents can cause trauma to the soft tissues, leading to the formation of blood blisters. These blisters are usually small and localized, resolving within a few days with no treatment required.

2. Hot Food or Beverage Burns

Consuming excessively hot food or beverages can scald the delicate tissues in the mouth, resulting in blood blisters. The high temperatures can cause burns, leading to the formation of fluid-filled sacs. It is essential to allow hot foods or drinks to cool down before consuming them to prevent such injuries.

3. Poorly Fitting Dentures or Braces

Ill-fitting dentures or braces can cause friction and irritation in the mouth, leading to blood blisters. The constant rubbing of the oral tissues against the ill-fitting appliances can result in discomfort and the formation of blisters.

4. Oral Infections

Certain oral infections, such as oral herpes or viral stomatitis, can cause blood blisters in the mouth. The symptoms include painful sores, blisters, and other symptoms like fever or swollen lymph nodes.

5. Allergic Reactions

In some cases, blood blisters in the mouth can result from an allergic reaction to certain foods, medications, or dental products. When the immune system reacts to an allergen, it can manifest as blisters or ulcers in the oral cavity.

6. Trauma or Injury

Accidental trauma or injury to the mouth, such as a fall or a sports-related incident, can cause blood blisters. The forceful impact can damage the blood vessels beneath the skin, leading to the formation of blisters. Applying ice packs and seeking medical attention can aid in the healing process.

7. Nutritional Deficiencies

Inadequate intake of essential nutrients, particularly vitamin C, vitamin K, and iron, can weaken the oral tissues, making them more prone to injuries and blood blister formation.

Maintaining a well-balanced diet that includes a variety of fruits, vegetables, and lean proteins can help prevent nutritional deficiencies and support oral health.

8. Oral Cancer

While rare, blood blisters in the mouth can be a symptom of oral cancer. Suppose you notice persistent or unusual blood blisters and other concerning signs like unexplained weight loss, difficulty swallowing, or a persistent sore throat. In that case, it is crucial to consult a healthcare professional for a thorough evaluation.
