Excellent new braces! I guess they have to be fairly bulky to accommodate the expansion screws. Will the screws be activated as part of your treatment?
Do you have to wear the braces 24/7? if you do, I imagine your speech will adapt pretty quickly.
Did you have a choice of acrylic colour? My first hawley retainer after fixed braces in 2012/3 was clear and it got stained with coffee drinking. When I got a replacement after losing it on holiday, I asked for transparent pink. By that point I was on nighttime wear only so I suppose staining was not really an issue anyway.
I went for a new retainer late last year and was told I had had some relapse and some loosening of two teeth through intermittent wearing of my retainer . So I have had to wear a new retainer 24/7 for 6 months to correct the relapse then for retention and now I am gradually reducing my daily hours of wearing it down to 12 by the end of 12 months. The acrylic is pink again. There was no discussion of choice of colour but I am happy with pink and would not want a more obvious colour. I guess if I had a bite plane or occlusal coverage, I might have asked for clear as being a little more discreet. i have not drunk tea or coffee with this retainer in, but have worn it whist drinking beer at the pub.
I remove the retainer for eating and presume you do the same?
