Dental expanders are orthodontic devices designed to address issues related to a narrow upper jaw or crowded teeth. These custom-fitted appliances are typically used in children and adolescents during their growth phase. The expander applies gentle pressure to the upper jaw, gradually widening the palate and creating additional space for proper tooth alignment.

At Noyce Orthodontics, we use this non-invasive treatment to correct crossbites, crowding, and other orthodontic issues by encouraging the natural growth of the jaw, ultimately improving overall dental function and aesthetics.

The Dental Expander Procedure 

The dental expander procedure typically involves several key steps. After a comprehensive orthodontic evaluation, a custom-fitted expander is designed to fit the patient's upper jaw. This appliance is commonly attached to the upper molars and is adjusted periodically by our orthodontist in St. Joseph and Maryville, MO.

During these adjustments, incremental pressure is applied, gradually widening the palate. Patients may experience a sensation of pressure, but discomfort is usually minimal. Regular communication with the orthodontist is essential for monitoring progress and addressing concerns.

The duration of the treatment varies, but once the desired expansion is achieved, the expander is often left in place to stabilize the results before moving on to additional orthodontic interventions if necessary. Overall, the dental expander procedure is a well-managed, patient-friendly process aimed at correcting issues related to the upper jaw and promoting optimal dental alignment. 

The Advantages of Using Dental Expanders 

Correcting a Narrow Upper Jaw

The primary function of dental expanders is to address a narrow upper jaw. By gradually widening the palate, these devices create additional space for proper tooth alignment, reducing the risk of crowding and other dental issues associated with a constricted upper jaw. 

Preventing and Correcting Crossbites

Dental expanders in St. Joseph and Maryville, MO, are effective in preventing and correcting crossbites, where the upper and lower teeth do not align correctly. By expanding the upper jaw, dental expanders ensure that the upper teeth fit perfectly over the lower teeth when biting. 

Addressing Crowded Teeth

A narrow upper jaw often contributes to crowded teeth. Dental expanders create space in the dental arch, alleviating crowding issues and facilitating the proper alignment of teeth. This can contribute to a more aesthetically pleasing and functional smile. 

Improving Facial Symmetry

Addressing a narrow upper jaw with dental expanders can improve facial symmetry. Dental expanders help create a harmonious and proportional facial appearance by promoting a more balanced jaw structure. 

Enhancing Airway and Breathing Function

A narrow upper jaw can sometimes contribute to breathing and airway issues, particularly in children. Dental expanders may improve airflow by widening the nasal passages, potentially addressing breathing difficulties. 

Dental expanders serve as dynamic tools in orthodontics, offering a non-invasive and effective solution to address narrow upper jaws and related dental issues.
