Malocclusion may be caused by one or more factors:
- Small Mouth: A small mouth can result in a limited amount of space for the teeth to grow. This can foster crowding once the permanent teeth erupt.
- Tongue Thrusting: Some children thrust their tongue forward, pressing it against the lips with a force that can result in the protrusion of teeth, or “open bite,” among other problems.
- Extra Teeth or Not Enough: Sometimes, a person can have extra teeth develop and/or protrude, or certain teeth that do not develop or protrude at all. If you have too many teeth or not enough, your bite can be affected. In addition, the untimely loss of baby teeth or traumatic injury to the face, mouth or jaw can also affect the bite.
- Misaligned Jaw and Bone Structure: A misaligned jaw or supporting bone structure can affect the bite and create malocclusion. Malocclusion may result in difficulty chewing and speaking, or otherwise impact the functionality of the teeth. Furthermore, malocclusion may contribute to other oral health conditions such as TMJ.
- Poor Muscular Functional Habits: Malocclusion may be caused by poor muscular functional habits such as thumb sucking during infancy.
