Do you wear one? I have 'em - they look like Invisalign braces/aligners (no wires). I had conventional braces for about two years, and they were removed sometime in 1999. I guess Invisalign hadn't come out yet.
I used to wear my retainer nightly, but then it became every other night, and then I just kind of dropped wearing them - except when it felt like my teeth were shifting and needed some discipline - about once a month.
I'm wearing them now, and it's uncomfortable. It feels like my gums are kind of aching and itching. Disgusting feeling.
Tell me about your retainer - when'd you get it, what kind, and how do you feel about it?
