What do you call this and how could you fix this?

[cymbeline]

On my left side of my face my teeth are on top of each other (upper overlapping lower slightly as they should) meaning I can fully bite down that side, however on my right side my upper premolars overlap fully meaning I can touch the underside of my upper premolars while biting down. I believe this explains why my right side of my face is less developed than my left. What do you call this and how can you fix it?

Probably crossbite

Yeah I have no idea, someone said a crossbite, which it may be, but it can also be mild crowding of the premolars?

This is moderate premoral crowding.
