What causes the blisters/lesions on the tongue?

In general, the painful lesions on the tongue have a variety of causes, and each factor exhibits different symptoms.

1) Canker Sores

Canker sores are a very common type of oral lesion, happens in the tongue, lips, cheeks, gums, and other oral tissues. They are very small-sized (1/3 of an inch in diameter) white or yellowish lesions with red borders. Dentists observed that such mouth sores happen due to hormonal changes, vitamin deficiency, stress, or celiac disease.

Typically, the canker sores go on their own within 7 to 10 days. If it persists for more than weeks, it will affect the organs of your body and lead to the following problems:

  • Skin rashes
  • Fever
  • Diarrhea
  • Pain in joints

2) Oral Candidiasis

It occurs with a weakened immune system that leads to the overgrowth of the candida fungus. People suffering from oral candidiasis develop white patches over the tongue and look like blisters. In most cases, it happens as a side effect of medications, antibiotics, and poorly fitted dental appliances.

The side effects of oral candidiasis include:

  • White patches inside the mouth
  • Bad taste
  • Cracked mouth corners

If you notice such white or red-colored patches exist in your mouth for more than weeks, consult your dentist because it might be a sign of diabetes, cancer, or even HIV.

3) Pemphigus Vulgaris

Pemphigus Vulgaris is a rare autoimmune disorder that causes blisters in the mouth and over the skin.

Desmogleins develop a bonding agent that keeps the skill cells adhere to the skin. When desmogleins are affected, the skin cells are isolated and it leads to developing chronic blisters on the skin.

Apart from the immune system compromised with medications, various factors are also linked to this condition. The important triggering elements include age, genes, stress, and bacterial infections.

4) Behcet’s Disease

This is an inflammatory condition triggered by medications, dietary and lifestyle changes. It causes swelling in the blood vessels and is followed by bumps, blisters on the tongue as well as other oral tissues as a warning sign.
