I got three spacers in yesterday. My ortho's assistant started out with the first one on the right side upper, and she said my contacts were so tight -- the tightest she's ever experienced -- she decided to start on the other side. So she successfully got two in on the left side and tried the right side again. She managed to get the third one in, but she couldn't pull it out into the donut shape because my contacts were just too tight; it was just wedged in between my teeth like a little ball. So she told me to come in this morning and she'd pull out the ball and try again -- hopefully it would loosen up.
My first day in the spacers went fine except for the fact that I couldn't really floss my upper arch -- tore about 10 feet of floss -- drove me crazy. It was just a bit annoying, but I thought to myself, "Oh, I think I can handle this for a few days," since I'm getting braced on Thursday.
I woke up this morning and started to get ready to go back to my ortho's office for that last spacer. I tried to floss behind that tooth that had the little spacer ball in front of it. Oh, man!! Did that knock me back!! I just about panicked! I felt like I needed a root canal! It was actually painful to the touch. The problem is I already had a root canal in that tooth, and it has a permanent crown. So I'm wondering now if that's the type of tooth movement pain I should expect to go through. The assistant pulled out the ball and managed to get another one in and pull it through donut like and then get another one behind that (yea! my teeth are moving!)
I'm going in Thursday morning for my upper arch. It looks like they're going to band three molars, and I'm getting Damon 3 clear on the six eye teeth and then silver brackets for the back teeth.
I'm sooooo excited!!!

So my journey begins!
I'll keep everyone posted, and hopefully it won't take me too long to learn how to post pics.
