Stumbled into this thread...
omg i didnt knw there's thing Damon thing...
had my braces when i was in form 3...
let's c...7 years back? gosh it's been so long!!!
did it for arnd 3k and had in on for 3 years...

i had rabbit teeth plus what we usually call "vampire's tooth" at my upper jaw
and there's another tooth located right behind one of my front tooth
yep, my condition was horrible
i couldnt actually bite properly with my front teeth... (eating wantan mee is a horrible process coz the noodles r vry thin)
the orthodontist told me that he would need to extract 4 of my teeth, "expand" my upper jaw, and of course there were many other processes

after the braces were removed, i waited for 1 week for d retainer to be done
and during tht period my front teeth already started to move!
my 2 front teeth kinda moved a lil in front
the orthodontist then tried to kinda forcefully push em back and pushed on the retainer
i chose the transparent retainer, broke it and got the metal 1

and now, after so many years, i still nid 2 wear a retainer at night coz the damn teeth keeps movin'

yep, i guess it's bcoz i grind my teeth at night
chose the transparent 1 bcoz initially need to wear it day n night for arnd few weeks if nt mistaken
the orthodontist didnt charge me for the replacement retainer though~must have earned enough
