What Causes Malocclusion and the Need for Orthodontic Treatment

Orthodontic treatment is an effective way to help individuals with misaligned teeth restore a straight and aesthetically pleasing smile. In daily life, many factors can affect dental alignment, ranging from poor habits to certain medical conditions. So, what exactly causes the need for orthodontic treatment? Let us introduce the common causes below.

1. Poor Oral Habits: Certain oral habits, such as finger sucking or mouth breathing in children, can lead to a narrowed dental arch or affect jaw development, resulting in crowded teeth.


2. Oversized Teeth: When teeth are too wide mesiodistally, it can cause crowding and misalignment.


3. Genetic Factors: Dental crowding has a strong hereditary component. From the crowding or misalignment of individual teeth to the crowding of multiple teeth, or even the degree of rotation of a single tooth, similar patterns can be observed in both parents and offspring. This genetic predisposition is well-documented, although the precise mechanisms are not yet fully understood.


4. Problems During the Mixed Dentition Period: Premature loss of primary teeth during the mixed dentition phase can cause adjacent teeth to shift forward into the gap, leading to insufficient space for permanent teeth to erupt properly, resulting in misalignment. Conversely, retained primary teeth can cause the permanent teeth to erupt in an abnormal position due to lack of space. Therefore, if a child has retained primary teeth, early extraction is recommended.


5. Insufficient Jaw Development: Inadequate jaw growth can lead to a discrepancy between jaw size and tooth size, preventing teeth from aligning properly within the alveolar bone, resulting in crowding and misalignment.


6. Periodontitis: In patients with periodontitis, alveolar bone resorption leads to tooth loosening and increased gaps between teeth. Most adults suffer from periodontal disease, which progresses slowly and often develops from gingivitis. Aside from occasional bleeding during brushing, there are few noticeable symptoms, making it easy to overlook. When gingivitis progresses to periodontitis, patients may experience severe halitosis, recurrent periodontal abscesses, tooth mobility, and increasingly wider gaps between teeth. In severe cases, tooth loss can occur.


7. Excessive Gaps Between Primary Teeth: During the primary and mixed dentition stages, it is normal for newly erupted front teeth to have wide gaps. Permanent teeth are larger and more numerous than primary teeth, and these gaps typically close once all permanent teeth have erupted. Conversely, if the primary teeth are too tightly spaced, there may not be enough room for the larger permanent teeth to emerge, leading to misalignment.


Friendly Reminder: The above provides a detailed introduction to the causes of malocclusion and the need for orthodontic treatment. We hope this has been helpful. Experts note that the success of orthodontic treatment largely depends on the cooperation between the patient and the doctor. Patients should follow their doctor's instructions, attend scheduled appointments, and avoid being overly impatient.
