So, 2012 is not starting out all that well.  Have been bothered with allergies this past week, thanks to all kinds of things growing due to the rain and warm weather.  Started getting worse on the 1st.  Now today, I went to the dentist to get a cavity filled and a new crown on that tooth.  When the crown came off, it looked like a root canal was in order.  The dentist was flummoxed.  Could not figure out how on earth I got a cavity where this one was.  Turned out after grinding for the fix - he found the game changing issue.  The tooth had fractured below the gum (and crown) line.  There is no way to save this tooth - so off with a temp filling and a referral to a periodontist to get an implant.  :-(
