I have a salivary stone that was diagnosed last year. the ent specialist recommended i return after a few weeks if it had not come out. i did not return and now i am in a different town. which type of doctor should i see?

Ideally same: Depending on local resources and process you might need to reestablish with a GP that will be able to make a referral to a local ENT. Another way to find out would be to call previous ENT’ s office and ask for a referral in the area you live now. That will help a lot continuity of care as medical information will become available to the new doc.
