I’m nearing the end of my treatment and was wondering whether removable retainers or permanent ones are better? If I chose removable, how often do I need to replace them? I hear sometimes they lose their effectiveness in a year. On the other hand, if I chose a permanent bonded retainer, how much longer would I have to wait post-braces to eat crunchy food again (to ensure the retainer doesn’t break soon after the ortho bonds it to my teeth?)

Thanks for your help!
