There are multiple benefits of getting your teeth straightened, including:
Having a beautiful smile you're proud to flash is always helpful when engaging in social activity. It influences how you see yourself, increases your self-esteem, and makes you a self-assured individual.
With an aligned bite, you would be able to chew and eat in a comfortable way. The position of your teeth has a significant effect on your speech abilities. Having well-aligned teeth allows you to enunciate clearly.
With straight teeth, it is easier to brush and floss, and so less likely for plaque to build up. Therefore bacteria is not left to multiply and affect gums, preventing the formation of cavities or gum disease.
