Hi Klobird,
No. I have had chronic wire slippage since last November.

Maybe because my bite is so uneven???? It got even worse after I "upgraded" to the really thick wire in December. I have self-ligating wires and for some reason the wire keeps slipping to my left and I would get some bad pokies out the back end there. After having about 1/2 inch of wire poking out over Christmas, the lead dental assistant showed me how to move the wire back into place on my own, but I was doing that at least twice a day. Last month, my dentist had the dental assistant put a bit of composite on that back molar/end of wire to keep the wire from being able to move back. It will be removed at some point.
I am getting a composite build up on my lower right #6 at my next appointment when the rest of my lower braces finally go on. It is a crown. After having the bracket pop off of the crown when I tried erupt that molar with elastics, he finally said I'm going to need a new higher crown when my treatment is completed so he is going to skip re-bracketing it again. Because my teeth don't touch when I bite, I'll have the build-up on that tooth for the duration of my treatment. I'll keep you posted after my appointment on the 23rd.
I'm really a bit nervous about my next appointment. I've been wearing a lower splint for 2 years that gave me a pretty good bite. With the "in between" state of my treatment now, only my back molars (#7's) touch on the left side and I'm not even close with the other teeth there. My right side doesn't have as big of a gap, but only the back molars currently touch there also. Unless I learn to chew with my front teeth, I'm imagining a lot of smoothies and soft food for a while.

My orthodontist swears he hasn't had anyone starve during his treatment though. I'm trusting him on this.

Ironically, before my orthodontic treatments began 2 years ago, my teeth touched and I didn't realize how severely bad my bite actually was. I was having major ear problems and hearing loss from my jaw being out of position and pushing back into my ears though. I just keep telling myself I'm doing the right thing and remembering to take it a day at a time.. I'm almost 10 1/2 months into treatment already.
