Funnily enough. I struggled with this in my youth. As a baby up until around age 6. I would suck my thumb subconsciously as I slept. Which meant that as my teeth grew. My two front teeth developed a slight overbite. Mine was never fixable. Due to the fact I didn’t need braces. My other teeth weren’t bad enough. And I tried Invisalign. But it never really seemed to make a difference.
For you, there’s a few avenues.
Braces
Jaw surgery
Invisalign
Elastics (rubber bands)
Have a look into these, see what looks positive to you. And enquire.
Bare in mind these all depend on how bad the actual overbite is.
