There is more appealing than a smile, with shiny, perfectly white teeth. Improving your appearance can improve your self-esteem, and that is definitely a good reason to want your teeth fixed. Misaligned teeth can cause problems that affect not only your dental health but your general well-being as well.
They are easier to clean, if you have straight teeth. In comparison, crooked crowded teeth provide hiding places for food debris which can increase the chances of bacteria and plaque accumulation. It hardens into plaque as this bacteria builds up, and eventually tarters. And the reverse is real, too. Too much space between the teeth can also contribute to the lodging of larger pieces of food between the teeth. It means that cavities and gum disease are more likely to occur.
