sounds like my problem! I have had my braces for more than a year and half. Last year, I had an oral surgeon open up the gum and put a button w/ chain on the impacted tooth. The baby tooth was removed. My ortho has been pulling the tooth down by tying a thin wire or rubbery string thing frm the chain to the archwire. Every 2 wks the ortho will retie the wire/or restring to tighten the pull. This is almost a year and the tooth is slowly coming down. The button is not visible enough yet to quicken the process. they need the button to show so at least they can use an elastic to attach to button and attach to my bottom brace. Anyway, as a result of them trying to pull down that freakin' tooth, the tightening wire or string is causing my upper teeth to go UP, making a space between my upper and lower teeth. augh! Next week, they will replace my upper archwire with a thicker wire so it's not so flexible and will prevent my upper teeth from going up.
I am just bearing with it. It's annoying, but I guess that's what I get for waiting so long to get my teeth fixed. I'm 31 so you're better off than I am! Because of this impacted tooth, this is causing my brace wear to be over 2 yrs... I'll just grin and bear it...if your upper teeth is going up like mine, they'll fix it in the end. Good luck!!!
