Got a water blister on roof of mouth. Why?

Not sure. It is likely a mucocele, a small mucous gland duct, which has been traumatized. Can be easily treated by a dentist if it doesn't disappear on its own.

Seek evaluation. It may be a mucocele, a minor salivary gland with a blocked duct. The only way to be sure, however, is to have it examined. Any mouth lesion that does not fully heal in two weeks deserves examination, so you're overdue. Would recommend that you see a specialist Oral Surgeon for evaluation and if necessary, treatment.

A trip to the ER. Blisters forming on mucous membranes (such as the inside of your mouth and lips) and/or elsewhere on your body could be signs of a serious reaction to a medication such as your antibiotic. Please look up Stevens - Johnson Syndrome for one example of many possible types of reactions. I recommend an urgent evaluation, preferably in the Emergency Department. Read more...
