Geographic and/or Fissured Tongue support group.
I got this idea from the TJM thread. Sometimes when I eat hot food, my tongue will become geographic after a few minutes but it usually goes away overnight. The sides of my tongue are fissured and I have a few cracks along the top of it...nothing very noticeable or worthy worrying about but I had assumed this was always normal up until the point I did a bit of research on it last night. There is no current "cure" for either of these things and from what I understand, the tongue cracks could potentially increase as you get older.
How many of you all have geographic or fissured tongues?
