A picture would be helpful

Detailed Answer:

Hello,

A single white blister under the tongue can be a common occurrence and is usually harmless and transitory. It may be related to a mild injury in the tongue or to an allergic reaction. If, however, there are more of them and they become painful a diagnosis of aphthous ulcers should be considered. I would advise you see an ENT specialist if the blister persists or becomes painful or increases in number.

Ultimately, for a more accurate answer, I would need to see a picture to get a better idea of the type of blister.

I hope this helps. Take care.
