How should i handle a hole in top palate? i also have a full front dental bridge, and sinus issues?

Not sure how your oral-antral communication formed, but you'll need to consult with an oral surgeon for treatment. These do not usually resolve on their own.

The hole in palate can be treated by an oral surgeon, but a consult by a otolaryngologist is highly recommended. Is hole congenital, or did you puncture the palate recently?

Treatment is predicated upon diagnosis. A hole in the palate has many possible causes such as cleft, bacterial infection, STD, trauma, neoplasm, etc. Please see an Oral Surgeon to begin the diagnostic process.
