I had braces in high school for 1.5 years & they insisted on taking my 4 premolar to prevent having too many teethes once my wisdom came out. Today, I just went to the dentist, and dr. gave me an option of extracting my top right wisdom tooth or do filling. She said my wisdom teeth is partially decayed and if it further decay..it can hit my nerve. I don't know what to do at this point. Also since the bottom teeth (wisdom) have no support from the top, will it affect the treatment?Help me?!
