Can i get braces just because?

Yes: You will have to pay for them however.

Because?: Can you get braces "just because"? Because of what? You don't need them but just want them for no particular reason? An ethical orthodontic specialist normally won't simply put braces on your teeth unless there is a reason for correcting something. But just "to have them"? I am doubting it, unless its for an acting part for a movie/tv/play.

Did you mean...?: that its not needed medically, but you have cosmetic things about your teeth you want to fix? If so, then sure, we can fix your teeth to look amazing! However, if your teeth and bite are already perfectly straight and you simply see braces as some form of fashion accessory, then no. The orthodontist would likely not do it and it simply makes no sense.
