I know this is impossible to know without seeing me but hopefully someone can ballpark it based on my description.
In middle school I had braces for like 3 years. Pallet expander, nightly headgear, everything.
When I got my braces off I stupidly didn’t wear my retainers and I’m 30 now and 2 of my front teeth are slightly bucked out again. Everything else looks straight still.
Do you think I’ll have to wear Invisalign for years again?
