I had my wisdom teeth pulled about two weeks ago. They weren't fully developed so I really don't have any big holes from where they were. However, on the bottom right there is a SMALL indentation in my cheek right by where the gums are but not where a tooth was. If I stick my tongue back there by the indentation there is a foul taste that comes, almost like a liquid but my guess is that its just saliva that's come across this area. What is it and how do I fix it.
