I was having off & on tooth discomfort & had it checked out by my dentist. He told me the tooth was cracked & needed to be removed by an oral surgeon. Went to an oral surgeon who said there's a small micro-crack in that tooth & to leave it alone, unless it becomes extremely painful. Because of this cracked tooth, My regular tooth cleaning was cancelled & my dentist won't reschedule me, until the tooth has been removed. This is a real dental Catch 22. Any advice/suggestions greatly appreciated.
