It's not just about aesthetics. Orthodontic treatment can prevent tooth decay, gum disease and subsequent early tooth loss, difficulty speaking clearly, difficulty of chewing properly, and also a problem with the jaw joint. The most common situations when orthodontic treatment needs to be considered is spacing, crowding or any "crooked" teeth, protruding teeth (overbites), deep bite, open bite, jaws or face asymmetry, but also teeth movements before making new veneers, crowns, or implants. Straight teeth and a beautiful smile can also increase your self-confidence, which is important for mental health.
