A visit or two may be enough to give the impression that you have straight teeth. This can be done with veneers that cover the teeth. Veneers offer a very quick solution but it is only a cosmetic solution and cannot be considered a permanent and long-lasting treatment. However, if you really want to have your teeth to be straightened, the improvements are not just cosmetic, but functional as well. Straight teeth through orthodontic treatment can also remain straight for the rest of your life.
