Life's been a bit hectic lately, so sorry for the delayed reply. I didn't get the go ahead for retainers, alas -- they still want to tweak a few teeth, so I have to wait 8 weeks for my enhancements. Sigh. I am so ready to be done with them!! I'm glad to hear the retainers might be good for bite guards ... I am kind of afeared of the costs once these are done.
