Can I put braces or invisalign over peg lateral? (photo)

I have a crooked bottom tooth because of crowding, i have perfectly aligned on the top but i have 2 peg lateral (i think that's what it's called) teeth. Should i get braces over the peg lateral teeth? if the braces fix the gaps I wouldn't really care about the size and shape. Is their a way i can fix the bottom tooth without braces? or the gaps without braces? i don't want to have remove the teeth while having braces on. also would invisailgn work?
