I've had a swelled water bubble on the roof of my mouth for many years -- I can't even remember when exactly this started.  At the beginning, it was at the back of the roof of my mouth.  Then it moved to the center of the soft tissue of the roof of my mouth.  Everytime at the exact same spot.  I used to have it less frequently than I do now.  About a year ago I noticed it started  coming back like two times in less than ten days.  It starts swelling and gets irritating, not painful, and then becomes like a water bubble the size of a small black lentil grain.  It lasts for ~ 12 hrs and then bursts.  The fluid is clear, salty and thick.  This leaves a sore unpainful spot that heals very quickly.  Normally spicy and sour foods causes it.  What do you recommend I do?

Have you seen a dentist or your primary care physician about it?  Since its salty and thick but not yellow, it may not be pus or an infection.  It may be a cold sore (herpes infection).  I would suggest going to your doctor (either one) and let them know.  They may be able to prescribe an anti-viral medication if that's what it is.  Also, do you get any warning signs prior to the bubble appearing?

Thanks for your answer.  I went to my primary care physician and he suggested a biopsy test.  The liquid is not yellow and I don't think it's an infection.  The issue is it's been happening to me for many years, but the frequency got higher.  Prior to the bubble appearing, the area gets red and a pit irritating, and small tiny bubbles would appear then the exact same spot would start to rise and get filled with liquid.  I appreciate any answers

Well the biopsy will give you the best answer to your question.  I would throw in a guess that its either a bad cold sore or a bad canker sore.  Once the biopsy is done, hopefully they'll be able to begin treatment and solve your issue.

Thanks again.  I will get back after I get the biopsy done.
