Your Baby Teeth. Baby teeth are softer than permanent teeth, which makes them particularly susceptible to acid found in liquids such as soda, juice and flavored waters. As a result, they become crooked. Furthermore, baby teeth get crooked for several reasons. Either they are too small for the available gum space, or when you were little, you sucked your thumb or pacifier too long that caused the crooked. Other cases like having a trauma to the mouth or tooth decay can also be a factor for the baby tooth to fall out prematurely. Hence, the permanent teeth may grow crooked too. More often than not, if the baby teeth happen to be crowded, the permanent teeth will be too. While genetics and hereditary are a factor to this, poor dental habits and/or poor nutrition can also be a problem at times.
