Still fighting parasthesia

So I got the "nerve" to call the dentist's office and left a message with the receptionist's voice mail, describing my issues and waiting for a response so I can schedule my first trip back to the dentist since November. So I've passed the 8-month mark and still have not fully regained the sensation in an area of my tongue on the right side. It's quite noticeable, and I hope it is not a permanent dead area, because when you are used to 100 percent feeling of an organ and that feeling is suddenly reduced, through no fault of your own, that is the pits. It's set for March 5 at 12:20 p.m. I'll let you know what happens.
