Crooked baby teeth are more likely to fall out earlier than straight baby teeth, and when they do, the permanent tooth that will take its place typically grows in the same direction. Crooked teeth also present difficulties when brushing, flossing, chewing, and speaking.
Digestion can also be affected in a major way, because chewing is part of the chemical process where your saliva breaks the food into simpler pieces. Having crooked teeth can complicate healthy chewing habits, which threatens digestion and nutritional development, especially in the case of children.
