He ended up replacing the band that had broken off (no spacers required this time) and removed and replaced the final band (the only one that hadn't broken off yet) to prevent it from doing the same thing all the rest did (break). Then he tightened my braces etc. And so far so good!
My progress is really becoming apparent now! I know I've got a long way to go b/c I still have huge gaps and I have a slight overbite that needs to be corrected, but my upper teeth are pretty straight and my lower ones are really getting there!
(IDK why my cell phone cam always makes my rubber bands look dingy, swear they don't look stained in person!)
(lower teeth, see that straggler really coming up and blending with the rest? :) )
