Small blisters or nodules on the tongue can be signs of a serious illness, but are usually no cause for concern.

Sores on the tongue and aphthae as well as blisters can be caused by herpes viruses, allergies, bacterial infections, immune disorders or serious diseases such as tuberculosis, cancer or syphilis.

 

Cancer

If there are blisters on both sides of the tongue, this is probably harmless. If there are blisters and lumps on one side, it may be cancerous and should be investigated. Weisores on the tongue, hard bumps or sores, especially if they are painless, can be a sign of cancer.

 

Irritated taste buds

The tongue is covered with papillae, which are the taste buds of the mouth. Occasionally these papillae become irritated or inflamed and form painful blisters on the tongue. This usually disappears on its own.

 

Fibroma

The most common type of blister or lump on the tongue is a fibroma and is benign. A fibroma is usually caused by accidentally biting the tongue. Some fibromas can stay for years. However, to be on the safe side, they should be removed and examined in this case.

 

Soor

Thrush or candidiasis can affect the mouth, armpits and genitals. In the mouth, thrush appears as curd-like patches on the tongue and the inside of the cheeks. Thrush is painful and should be treated with medication.

 

Oral herpes

Unprotected oral sex can lead to oral herpes, which takes the form of sores on the tip of the tongue, the palate, the throat and the inside of the cheeks. The lesions can be translucent, white or yellowish and are closely spaced blisters.

 

If you are unsure about any unusual blisters or painful sores in your mouth, you should see a doctor.
