If you are just starting Invisalign treatment, I have some thoughts for you. If you have completed it and are in retainer phase, this might not apply.
Be sure you are clear on orthodontist visits required during the active alignment period. I used Invisalign a few years ago and had routine orthodontist appointments at regular intervals to assess progress. Much depends on how aggressively your teeth need to be treated - how many sets of unique aligners, how often they are changed, how frequently you see the doctor, how many hours a day you must keep them in, before that glorious day comes when a set of heavier-weight clear retainers are made, and you can ratchet down to night-time wear or whatever is prescribed to preserve your new alignment. There is also a waiting period while your custom aligner sets are made, after the visit where the yummy purple goo is used to make an initial impression tray.
You won’t be seeing an orthodontist for this kind of thing during Plebe Summer. Take the time to do the (I love this Pentagon phrase, it is so apt) tooth-to-tail analysis on this, and never assume anything. Invisalign only works if you complete the full alignment cycle and faithfully manage your retainer regimen; it’s not inexpensive, as you know.
