If what you describe is actually the case, then this may be the first case in .org history where someone asks if they need an expander, and they actually need it. I would 100% recommend you talk to your parents and see an orthodontist. Btw at 16 you may not get a palate expander, it depends on if your midpalatal suture has fused or not, which usually occurs around that age, if it already has you're getting MSE or something similar.
I am probably exaggerating the crowding and tounge not fully fiting, I got invisiline and wore it for 2 years and was never recommended for an expander. Can u see the photo?
Yes I saw the photo, without a measurement I can't really tell if it's narrow or not, but from look alone I think it is narrow. Again, if you have any concerns or actually have these symptoms, there's no harm in at the very least seeing an orthodontist and asking about it. If you feel your parents will not take you there for such a reason, then just wait until your next dentist appointment and ask them about it.
