What are these blisters white dots on tongue?

There are a few different possible causes of white dots or blisters on the tongue. Here are a few of the most common:

* Canker sores: These are small, round ulcers that can form on the tongue, inside of the cheeks, or on the gums. They are usually white or yellow in color and can be painful. Canker sores are typically caused by trauma to the mouth, such as biting the tongue or cheek, or by eating certain foods that can trigger an allergic reaction.

* Herpangina: This is a viral infection that causes small blisters to form on the tongue, tonsils, and back of the throat. The blisters are usually white or yellow in color and can be painful. Herpangina is most common in children and is typically spread through contact with an infected person's saliva.

* Hand, foot, and mouth disease: This is a viral infection that causes fever, rash, and blisters on the hands, feet, and mouth. The blisters on the tongue are usually white or yellow in color and can be painful. Hand, foot, and mouth disease is most common in children and is typically spread through contact with an infected person's saliva or feces.

* Oral candidiasis: This is a fungal infection that can cause white or yellow patches to form on the tongue, gums, and inside of the cheeks. Oral candidiasis is most common in people with weakened immune systems, such as those with HIV/AIDS or diabetes.

If you have white dots or blisters on your tongue, it is important to see a doctor to determine the cause and get appropriate treatment.
