A fitting of sorts

This week I was back to Dr. F. He he fitted me for my palate expander. He took out the spacer and fitted my two (one in from the back) molars with rings and took a mold of my upper teeth. It would seem those rings will be attached to the palate expander. Then in an evil twist of fate he put new spacers in. My teeth have been a little tender, though not too bad, but now one of the spacers digs into my gums whenever I bite into it. I suppose that wont seem so bad when I get the palate expander in... That's just a week and a half away.
