Should I put on braces? (Photo)

My two front teeth in the lowe jaw are slightly gone astray (as you can see from photo 1) but when i smile theese teeth cannot be seen by others (as you can see by photo 2), but only when i open my mouth and laugh. I think i should point that my problem is aesthetic and not because i have a tooth ache or my teeth dont sit well with one another. I am 20 years old male. Should i visit a dentist and probably put braces?
