Gum Grafting - Round 2

I went to my periodontist today to have my gum graft looked at as it is supposed to be healed by now.
Apparently I heal beautifully and the graft took "remarkably well" - yeah for me!
Now I have to have my second round of gum grafting which is going to be in February. Boo for me.
It is not the most unpleasant experience I have ever encountered, but it is also not the most fun one can have on a day off.
However, there will be no root erosion for my teeth. No way.
Yet - the sad part, I thought that I had already paid for both grafts up front.
No
no

no.
I have to still pay for the second round, which thankfully my benefits cover the majority of but not completely all.
