Tongue blisters are painful sores which makes it difficult for you to eat or drink anything. You can also feel pain while speaking. In fact, any such activity that involves the use of tongue becomes a painful affair because of these blisters. It is more common in adolescents and young adults. However, that does not mean that it does not occur in infants, small children, and older adults. Even they are bothered by it, but less frequently.
There are various forms of blisters and each of them emerges for some different reason. You may get just one single bump on tongue or may have them in clusters. Their causes and characteristics are discussed below:
Fever Blisters: They are also known as cold sores and are caused due to infection by herpes simplex virus type 1. These appear on both inside as well as outside the oral cavity and are accompanied by some more symptoms like swollen lymph nodes. Excessive stress, weak immune system, trauma, exposure to ultraviolet radiation, cold, flu, or fever can be the cause of cold sores.
Canker Sores: Medically, they are known as aphthous ulcers. Even though they look very similar to fever blisters, they have different characteristics. Firstly, canker sore is not contagious like fever blisters. It occurs inside the mouth only and is comparatively bigger in size. The exact cause behind this problem is not clearly known. It may run in families. Vitamin deficiencies, food allergies/sensitiveness, stress, hormonal changes, certain environmental factors, certain bowel diseases, use of toothpastes containing sodium lauryl sulfate, etc., can cause canker sores.
Hand, Foot and Mouth Disease: This is a viral infection that mostly affects small children. It is characterized by painful, red blisters on tongue and other parts of the mouth along with skin rashes on palms, feet, toes and fingers. These blisters often develop into ulcer after a few days.
Yeast Infection: A white bump on tongue could be a sign of a fungal infection. This is also known as oral thrush or candidiasis and is caused by a fungus named Candida albicans. Before the creamy white lesions appear, the tongue becomes swollen and painful.
Bacterial Infection: Staphylococcus bacteria is mainly responsible for these blisters. This bacteria grows in the gums first and later on the infection spreads to the tongue.
Food Allergy: Another common cause is food allergy. Those who are allergic to some foods components like eggs, milk or peanuts get sores if they consume that particular food. Sometimes, it is accompanied by upset stomach.
Deficiency of Vitamin B: People with vitamin B deficiency usually experience blisters in mouth as their immunity towards bacterial infection, decreases. The best way to get rid of this problem is to include food rich in vitamin B complex.
Minor Injuries: Injuries on the tongue is quite a common occurrence. It can happen due to accidental biting, brushing with hard bristled toothbrush, consuming hot food or during some dental procedure. This kind of injury often leads to growth of blisters on the site of injury.
Other Causes: A few other factors can be responsible for the eruption of bumps on tongue. It includes side effects of certain medicines, unhealthy eating habits, hormonal changes, tonsillitis, anemia, changes in the immune system and so on.
In general, these blisters last for around a week and then disappear on their own. Therefore, no medical treatment is required. However, if they refuse to go, if the size of the blisters increases or if you are getting them quite frequently, then it is advisable to visit a doctor. The doctor will ascertain the cause and treat it accordingly.
