Having crooked teeth leads to higher chance of developing a gum infection (periodontitis). Gum infection causes oral bacterias to travel to a heart and allow the bacterias to accumulate around the heart valves. Bacterial accumulation around the heart valve will lead to a heart disease (e.g., heart attack). By having straight teeth, it's much easier to keep teeth clean and prevent a hard buildup that causes gum infection. Invisalign is clear braces that can comfotably correct crooked teeth and make your heart stay healthy.
