I had really bad teeth as a kid, so had braces. Periodically I'd have to go in to get them tightened, and remember the worst whole head pain for a day. Just curious is switching Invisalign molds is a similar process?
Nice! I hope no kid today has to go through that. It's easy to say it's worth it now that I'm 30 years removed and have straight teeth, but still have vivid memories of those awful days.
