When it is applicable to get a braces for the upper teeth? :) or should i go full braces? :)

Orthodontics: To give you the correct advice, it would be necessary to examine you and your bite. Even then, each orthodontist may look at your condition a bit differently. Why not seek the opinion of a local orthodontist, someone who can actually treat you ?

Generally: Generally it is appropriate to treat both arches to make sure that they fit and function best with each other. But malocclusions are like snowflakes, no 2 are exactly alike. Seek evaluation by a specialist Orthodontist for answer that best fits your problem.
