Causes of Crooked Teeth

Crooked teeth can affect the alignment of teeth, resulting in an uneven bite and an aesthetically displeasing smile. There are several causes of crooked teeth, including genetics, jaw size and shape, and poor oral habits. It is essential to understand the causes of crooked teeth so that one can seek the appropriate orthodontic treatment.


Genetic factors significantly influence the development of crooked teeth. You could be more likely to inherit this trait if your parents or other family members do. The size, form, and position of teeth as well as the size and shape of the jaw can all be influenced by genetics, which can impact how teeth line up.

Size and shape of the jaw

The jaw’s size and shape can affect how well teeth line up. The size or shape of the jaw may impact the placement of teeth. A small jaw, for instance, might not have adequate room for all the teeth, causing crowding or overlapping. On the other hand, a broad jaw may leave spaces between teeth, leading to tooth movement.

Pacifiers and Tongue Thrusting

The use of pacifiers or thumb suckers for an extended period after three to four years may result in alterations to the alignment of the teeth. These behaviors may place stress on the baby’s teeth, resulting in malocclusions. Tongue thrusting occurs when the tongue pushes against the front teeth rather than the roof of the mouth. This constant pressure can cause teeth to shift, especially the front teeth, resulting in an open bite or an overbite.

Poor Oral Hygiene

Poor oral hygiene can lead to dental problems, including gum disease and tooth loss, ultimately influencing how the teeth line up. Bone loss surrounding the teeth due to gum disease can result in tooth movement and misalignment.
