I had braces when I was maybe 13? Only had them for less than 2 years. Ever since then I have had the clear retainers. I'm almost 25 now and the need to continue wearing them every night remains apparent. Like many others, when my wisdom teeth grew in there was a bit of shifting and I still have them (dentist doesn't think I need them pulled) so my retainer does a bit of work at keeping this shifting under control.
I'm not good about wearing my retainer every night bc.. you know.. not exactly sexy to kiss DH with plastic in my mouth (guess it's better than the sleep apnea face masks) so I don't always put it in before falling asleep. And if I skip a couple nights there's shifting and my retainer doesn't fit back in as easily.
Do I really need to wear my retainer every night for the rest of my life? Or if I'm diligent about it for a certain amount of time will my teeth finally settle?
ETA- Do you ever get your retainer replaced with a new one? I imagine so, right? I can't remember the last time I had mine replaced... It would be nice to have a nice new clear one. I clean it obviously but it gets weird-looking over time regardless.
