The position of our teeth is influenced by a combination of environmental factors and our genetic makeup. While braces and orthodontic treatments can correct misalignments, the root causes often lie in ancestral dental characteristics. Genetics determine the skeletal framework of the face, dental quantity, and 墨田区 前歯矯正 mouth anatomy. For example, if a parent has a underdeveloped mandible, their child is more likely to inherit the same trait, which can lead to misalignment caused by constrained arch length. Conversely, an overgrown jawbone might result in diastemas and spacing issues.

Genes also affect the developmental schedule of dentition and occlusal relationships. Conditions such as malocclusions like deep bite or edge-to-edge occlusion often run in families because they are linked to inherited craniofacial morphologies.
