Crooked teeth can be caused by a variety of factors, including hereditary predispositions, prolonged thumb-sucking, dental injuries, and poorly performed restorative dental procedures.
Factors That May Cause Crooked Teeth
Crooked teeth can be uncomfortable, and they can lead to other dental problems as a person ages. Misaligned bites are often caused by genetic factors such as upper and lower jaws that are not proportionately sized. Thumb sucking can also make a major contribution to the way your teeth line up in your mouth. Other common causes of crooked teeth include injuries, premature loss of deciduous or baby teeth, and restorative dentistry procedures that are improperly done.
Improperly Aligned Teeth
When the upper and lower jaws are not the same size, the result can be a malocclusion or a poorly aligned bite. An overbite is often caused by a lower jaw that is disproportionately smaller than the upper jaw so that the upper teeth fall over the lower teeth. Alternatively, if the lower jaw is larger than the upper jaw, lower teeth may appear to jut out. Such conditions are hereditary, so it is likely if one of your parents needed braces to correct an overbite, you will, too.
Prolonged thumb sucking can also affect the way teeth line up, and in some cases, may even cause mild deformations of the jaw. Chronic thumb-sucking puts pressure on the upper teeth, which has the potential to tip the upper incisor teeth forward and the lower incisor teeth toward the tongue. Occasionally, thumb sucking will leave a gap between the upper teeth and the lower teeth when the back teeth are clamped together that is exactly the size of the child’s thumb. Sucking particularly hard can lead to crossbite, a condition in which the upper jaw is too narrow to align properly against the lower jaw.
Misaligned Bites Can Be Remedied
In the majority of cases, misaligned bites caused by hereditary factors and thumb sucking can be fixed by braces that shift the jawline into place over an interval that ranges from six months to two years.
